SOURCE: battery will not stay charged

Check the battery strength and then double check your alternator to make sure it's charging.. I installed 3 alternators, new off the shelf, on one vehicle, and all three were duds (4th one worked fine). If the battery does not need replacing, and the alternator is charging, double check and make sure no components are left on such as a light in the glove box.

SOURCE: Fusible link wire gets really hot.

Removing the two smaller wires stops the exciter current to the alt which stops it charging.
Usually if a wire is getting hot its because:
A: Current overload..
B: Corrosion in wire restricting current.
C: Corroded terminal.

Are the connections really dirty at the voltage regulator? These tend to get corrosion on them and cause weird charging system issues. Also make sure the ground is good on the regulator.

1986 diesel isuzu pickup standard 2.2l 4cyl. A New alternator installed. But still its draining battery, (did engine stall) or does battery drain parked?


The voltage regulator type depends on which alternator you have (there are 2 different ones), on one the regulator is attached to the outside of the alternator and the other it is separate and mounted on the firewall I think. See pictures below so you can ID what you have.

I have an 86 toyota pcickup battery charge light is on have good battery and replaced alternator twice.


i think you have an external voltage regulator in that year , ck that first . The easy way to tell if it has an external regulator ,if it has carburated it has an external regulator if its fuel-injected its internal regulator in side the alternator.Have you checked to see how much voltage the charging system is putting out at an idle ? It should be around 13.5 volts to 14.5 volts any less then 12.5 charge light won't go out.

I have a 1993 GMC 4x4 350 suburban that keeps discharging the battery. I have replaced the alternator and still discharge the battery. I was told that it needed a voltage regulator but can not locate where...


The voltage regulator is built into the Alternator. Take out the Alternator and have it
tested at your local Auto Parts store (they all do it free). This will tell you if the Alternator
is your problem or if you need to check elsewhere.

I am having a voltage issue with my 2003 gmc 1500hd 6.0L. I replaced the battery last week and had the alternator checked this past weekend and it checked out fine. Problem: At idle speed the voltage drops...


No. It is a bad alternator. When they test the alternator they turn it at faster rpm. When it turns at faster rpm it is charging fine. What the problem is the voltage regulator in the alternator is going bad. When you turn your blinker on I bet the voltage shows on the gauge. Moves up and down with the blinker.
