Battery won't recharge

Showing 3 out of 3 Posts
Question From Guest on Battery won't recharge

I own a 1989 Ford bronco II V6 engine. Recently the battery gauge has been going lower and lower closer to eight volts and occasionally when turned on the charge goes up again to the middle of the gauge. I've tightened the altenator belt, no help, got the alternator tested, it was good, and got the battery tested, that was also good. The only other thing i have noticed is the battery clamps are corroded. could it be it's enough to start the car but not enough to complete the circuit to charge the battery?

Response From Tom Greenleaf Top Rated Answer

?? Clean up all the battery cable ends - all ends! At least rule that out.

Charge this battery with a separate charger. It's possible that a bad battery is causing issues by itself,

94 Bronco turn on head lights and the Truck stalls

Showing 5 out of 6 Posts | Show 1 Hidden Posts
Question From craig47 on 94 Bronco turn on head lights and the Truck stalls

Hi, can anyone help?
I have a 1994 Ford Bronco 302 V8 302,000.00 miles (origonal) runs good but all of a sudden today while its running i turn on the head lights and it kills the engine. The alternator is putting out the correct voltage I can have all the electrical items in operation at the same time with no problem but turn on the head lights and the engine just dies. Any ideas out there???? Oh if i turn off the lights it fires right up, Thanks ahead of time, any help on this one would be GReatly appriciated.

Response From Loren Champlain Sr

craig; You stated that the alternator is putting out correct voltage. What voltage? and what amperage output?
The voltage should be in the 13.6-14.6V range. Not sure of the amp rating of your alternator, but 60A should be bare minimum, probably higher. I've never heard of a headlamp switch shorting to ground, but I suppose anything is possible.

Response From craig47

Ok i have done some more work and trouble shooting, heres what happened.

The altenator is fine 14.5v 85amp i found out when the truck is running the right front head light glows very dim with the switch off and the right turn indicator on the dash glows dim also. This gets even better if i unplug the right head lamp the truck won't start if i plug it back in it starts. If i turn on the egnition key and don't start the engine the lights don't come on, start the engine the lights glow.
I had the dash apart all the way to check wiring harness for obvious shorts and all looks good. If i isolate the main head light switch by un plugging it and start the engine the lights still glow and if i unplug the multi switch (turn ind switch) start the engine the lights still glow. The right head light when i turn on the lights is not as bright as it should be and when i turn on the high beams it gets dimmer. This is with the engine off because if i turn on the headlighs with the engine running it kills the engine. I am not blowing any fuses??? could this be a short in a switch like the ignition switch? my ignition switch is getting pretty worn 302,000.0 miles but still works

Any ideas where to look next would be great.

Thanks for any help/guidance
Craig47

Response From Loren Champlain Sr Top Rated Answer

craig; This is a strange one, I must admit. It really smacks of a bad ground, somewhere. The 'worn ignition switch'...the ignition/key tumbler is just a mechanical item. The actual ignition switch (an electrical part) is mounted lower on the column. I have never had one create symptoms like this, but this isn't a perfect world.
We've got some guys here that are sharp with electrical issues...hopefully, one will see this and jump in to give some more ideas?

Response From Tom Greenleaf

Agreed - this is a bad ground as Loren suggested. They are all over the vehicle to groung the engine block to the body and either get broken or look good and don't work. Sometimes plain adding them is the easiest solution.

They look like this - uninsulated suckers.........



just buy what you need as I think because you said headlights dimmed that the puter is not getting proper voltage either and causing the issues. Add these or chase down OE ones and clean them. There can be many in the car, block to chassis metal, dash to know chassis metal, even exhaust and trans to body and or from thru the vehicle,

Adding caused no harm is placed out of harm's way to do that,

T

Response From Double J

I dont know Fords all that well but this reminds me of the problem older Chevy Vans had at the bulkhead connector where the wiring melts/burns .It allows the vehicle to start but when the headlamps are turned on the vehicles would stall.
Usually any added draw like stepping on the brakes,turning on the blower,radio etc would overheat the burnt terminal and cause the vehicle to stall.


Just a thought...

1990 bronco voltage drop at idle

Showing 3 out of 3 Posts
Question From Nov on 1990 bronco voltage drop at idle

1990 ford bronco xlt
351W V8 5.8L
250000+ miles

My multimeter unfortunately broke on me so I can't provide current voltage levels. I'll be getting a new one soon. If I decide to believe my instrument gauge than the drop is quite dramatic. (6 volts+)

So here's the symptoms:
-At low idle (600-650 rpm), or when using any accesories the voltage drop kicks in.
-lights dim, gauge drops, radio cuts out.
-failed emissions, just the idle portion.
-Tested affecting accessories include all windows, climate control blower, rear defrost, headlights, wipers, turn signals. They CAN all be on at once without engine dying, but dim.

Also notable is that this happens when the engine is OFF as well (radio, lights...) the only time everything works fine is at 1000+ rpm

I've tried:
-Replaced battery, both batt cables, starter & solenoid, alternator.
-Checked grounds for battery and frame/block connection
-removed, replaced & cleaned up radio wiring (was a crappy custom job, it's good now. Problem still occurred with radio and amp disconnected.)
-Checked all fuses.

Help please!

Response From Tom Greenleaf Top Rated Answer

Just a guess for now: Try adding ground from engine block to body or if you see the ground straps it should have clean those up too. You can just add them if placed out of harms way and this is a maybe as a cause of the issues,

Response From Nov

Previously checked (added one for good measure). It's good.

Loud engine squeal and overheating

Showing 3 out of 8 Posts | Show 5 Hidden Posts
Question From m_fenix on Loud engine squeal and overheating

A month ago my 1981 Ford Bronco with a 4.9L 6 cylinder started making a squeal. At first it began after I was driving for a few minutes. it started with a low squeal which progressively got worse the more I drove. if I sat at idle the sound would slowly go away.
I had a mechanic friend look at it and of course he said to check the belts. So I changed them. The sound was still there.
He then said it could be the alternator. I had it checked and it was good, but I got a new one any way. The sound was still there.
I then brought to another mechanic who said it might be the water pump. It was a cheap part so I swapped it. This is where things got worse. After I swapped it, it ran fine at idle for a few minutes then the sound came on after a few minutes of idling and extremely loud. It's the loudest I've ever heard it. It doesn't go away and now my engine over heats as well. It never over heated before. WTF!!
I've checked and rechecked my hoses. Everything is good. I used a tube to try and get a better idea of where the sound is coming from and it sounds like its coming from the engine block right behind the water pump and next to the alternator.
There's also a lot of white smoke that dumps out of the tail pipe. I'm assuming this is related.

Please help me. I'm at my wits end here and I don't have money to go to a mechanic. I know it's not a belt issue.

Response From Tom Greenleaf

Hmmm? Could be a few things still. Is belt tension tight enough? Fan clutch ok? You can either take belt off and spin items by hand or a listening rod (careful with moving parts if you attempt that) to find a bad bearing or source. There are also mechanics stethoscopes - less dangerous to use for that.

Noise and overheat suggests (can only guess) loose belt, fan clutch inoperative w bad bearings, or an outside chance of wrong water pump and another reason for the noise. Not sure but some truck engines are counter rotating for trucks and not for ones used in cars that could have the same size engine and impellers if backwards won't pump the coolant around properly. That wouldn't account for the noise though IMO.

At the moment the only common problem that could cause both overheat and noise would be the fan clutch but can't be certain. There should be near zero freeplay and it might not make a peep spinning it by hand (engine off please) but need engine speeds to act up. Can you feel a decent air flow going thru radiator and is it warm when thermostat is open - upper hose would be warm so you know it has opened. Coolant must be known full too at radiator not just recovery tank.

One more thing to test. Cool engine, take belt off and run engine (short time only) without the belt. If noise is gone the noise would be a belt/belt driven item. If still there there's more to diagnose,

Ok, I’ve tried some stuff. And somehow it went back to how it was before I changed the water pump. I don’t get it. I simply took off all the belts and emptied the radiator then put everything back and refilled the radiator. Now everything sounds fine except after normal driving for a few miles the sound starts up slowly and decreases again when I come to a stop. Then starts back up when I begin driving again.
The belts are tight. It’s not the belts. Also, it’s not the fan clutch. The thermostat is working as well. I’m still stumped.

How are you sure it's not belt or fan clutch? When fully warmed up or beginning to overheat you should feel the hot air off the fan blowing hard at the engine. Fan clutches are usually only good for about 5 years. Common item.

If you watch warm engine and have a helper just shut motor off the fan clutch should stop in about one turn or it's junk. Right now it's the only common denominator I can think of for both noise and overheating,

I really appreciate the help. Thanks.
The reason I know it's not the fan clutch is because that year of Bronco doesn't have one. Or at least mine doesn't. Also, it's not overheating anymore. The temp is good. I just don't get it.
Here's everything that happens: When I first start it, everything is fine. No sound. No overheating. After it's warmed up and I start driving, the sound usually starts about a mile or two down the road. When it does start My speed reaches about 35 MPH. Once I come to a stop the sound slowly starts to lessen and eventually go away. I returns again once I start driving. And this repeats.
When I pull over and listen I hear the location of the sound is around the alternator, which is bolted to the lower front part of the block. I know it's not a belt tightness issue. There's no tensioner either because it doesn't have a serpentine belt. The power steering, alternator, and smog pump all have their own belts which come off the water pump.

If I missed it - sorry. Will this noise quit with the belts off? Important to know that so we can stop looking for anything belt driven.

Overheat (think already said) could be a suddenly clogged radiator but again that doesn't add up with conjunction with noise??

Right - if no fan clutch and it's blowing the correct way that wouldn't be it.

Again - feel for heat blowing thru the radiator. If nothing we need those clues to narrow down an approach. Noise is frequently fussy to find and diagnose. There could be an engine bearing for noise and yet again don't think that lines up with the overheating?? It's hard not being there with this issue,

There is no sound when the belts are off and the engine is running.
The radiator is flowing fine as well. No clogs.
I know it’s difficult to diagnose not seeing it. Thanks for trying.
What bearings could it be?

Response From Tom Greenleaf

That's good news as a belt driven item should be cheaper and easier than some internal problem. Again - feel for warm air flow coming from the fan when t-stat is open. Repeat - is fan blowing the right way?

Hey - anyone jump in. I can't think of anything but a bad fan clutch so far still that can both make noise and allow over heats when everything else checks out.
