Question about 1994 Chevrolet K1500

2 Answers

93 model chevy 1500 5.0L 4x2 eating alternators. The alternator is overcharging. Someone in the past has done away with the fusible link from the alt. to the positive battery cable end and put in a circuit breaker. The circuit breaker is 50 amp and will only stay engaged for about 5-6 seconds and then trips. If you jump the breaker, things get hot pretty quick. Have tried another battery. Have found no wiring shorted anywhere.

If the wires are overheating and someone put a rather large 50 amp breaker in the line, there might be wiring that is too thin between the alternator and the positive battery terminal.

I would probably replace the wiring with the proper gauge between these two entities.

When the wires get hot, it usually means they are not of the proper thickness or gauge all the way from point A to point B on a DC circuit.

It's like running too thin of an extension wire in an AC circuit.

Is there a fusable link that would keep the alternator from charging battery in a 1991 chevy corsica


Yes, I believe that would be a fusible link, rather than a large fuse (maxi-fuse) used on later models. The fusible links will tie into the positive battery cable somewhere. If not at the battery, then look for them where the positive cable connects to the starter. A bad fusible link will look like some of the insulation melted, may have bumps and bulges where the fusible link blew out. To replace a link, you cut it out and solder in a new link of the same rating.

Do the 2006 cobalt have a alternator fuse and if so where is it?


There is a fusible link in the wire from the starter to back of the alternator .The heavier gage wire . Measure voltage at the wire on back of alternator ,if there is B+ voltage the fusible link isn't blown . The two wires in the connector are from the PCM - engine computer . Do not touch those wires ,you can fry the PCM .Your charging system is computer controlled , if not familiar with this I suggest you take it to someone who is .

Brand new battery and alternator but the alternator won't charge the battery, why?


two possibilities that immediately come to my mind from past experience:

(1) check that 2-connector plug on the side of the alternator! if that is disconnected, or not connected tightly, the alternator will not work until the engine is revved up to about 3000. once the engine hits 3000 RPMs the alternator energizes itself and begins to charge.

(2) check the fusible links. they're in a small compartment next to the battery. I remember something about this happening to mine and it was a fusible link. there are 4 of them, the main one says "ALT NAT/BATTERY" and the next one says "IGN SW"... check those two. I'm willing to bet it's that fusible link. I remember that the car started ok but nothing else electric worked. furthermore, with that fusible link broken, the charge indicator (battery) light came on very dim when the ignition switch was off. did you accidentally short something when you did the alternator? I bet this is what's causing that.

94 pontiac bonneville... eats alternators, stalls at times, this is the second bonneville that has done this to me...and have heard of others that have nevver got fixed... car has no fancy aftermarket...


i have a 94 pontiac bonneville that stalls while driving. It seems to die always when I drive the car for more than 20 minutes. (During traffic) It recently has had a tune up (oil, oil filter, plug, wires) Replace module and fuel filter as well. I have had two different mechanics look at my car and no codes showed up for them. They mentioned fuel pump and crank sensor, which they CAN'T guarantee this will fix the problem. I've done some research online and have read that people with same problem have replaced both and this did not fix the problem. Any other suggestions??????

No charge to battery


IN ORDER:
Check the 120amp Alternator Fusible link#13 (for 2002 model) located in the fusible link block. (Note: a fusible link is a properly sized piece of wire that is designed to provide major protection when a short occurs) as regular fuses provide minor issue protection.

Check the 5amp ALT-S fuse as this directly affects charging.

Lastly check the 10amp IG2 fuse.

You may find that you have now have a spare alternator (your orginal that was ok) OR You can always sell it on ebay or craigslist.

Double check your fusible links at the starter solonoid. If one of them is burned, the charging system will not work. I'm assuming the control box you're referring to is the voltage regulator. Trace the wiring between the regulator and the alternator as well. I've had to run new wiring between the two before especially on the early iron. I have a 68 Mustang myself and had the same issue before and decided to use a Chevy 1 wire alternator instead. Definitely a much more simple set up being that the regulator is built in. It looks stock and I was able to clean up excess wiring in the engine bay for a cleaner look. Let me know if you'd like step by step installation of the Chevy alternator. It's very simple. My email address is proracer88@live.com. I've had problems in the past receiving emails so I may need yours so I can get you the information. Try this address as well tiqautoperformance@live.com. I'm really big into the early Mustangs. Mine runs a 331 stroker with a 4400 converter/C-4 reverse pattern trans. with an 8in. rear, 4.11 gears. Goes 11.81 @ 114 on pump gas and I drive it all over the place. Never gets over 170 degrees on a really hot day either.
