What to do if your alternator is burning hot?
Click to expand… Alternator needs a good ground path back to the battery. Make sure your ground cable and alt mount have a good path to the battery. Ditto on the pos cable as well. Then you can move on to the mechanical side if it is still burning hot (they do run warm though).
Do you need to check the battery first before checking the alternator?
Check the battery first. The battery is needed to start the vehicle, which, in turn spins the alternator at sufficient speed to keep the battery charged.
Is there a problem with my alternator and battery?
Check the two fusible links in picture they should have battery voltage both sides. The problem may be the PCM but lets run some tests first. Check out the diagrams (Below). Please let us know what you find.
How can I tell if my alternator is in high gear?
Start the vehicle and rev the engine to 2,000 RPM. This will draw power on your battery, which should cause your voltage regulator to kick the alternator into high gear. Keep the engine running and retest the battery with the voltmeter. When you read the voltmeter this time, the voltage should go up to at least 13.

If you have a charge light, then, use a wire length to connect the number 4 wire from the old remote mounted regulator connector, to the number 1 terminal on the alternator, the light will work as stock, done, finished. DIRT SIMPLE, I’VE BEEN DOING IT THIS WAY FOR OVER 25 YEARS, NO PROBLEMS.
What happens when an alternator heats up in a car?
As the alternator heats up the charge of the battery begins to drop until the point where the battery drains and the car dies. After sitting for enough time for the alternator to completely cool off the car will start up fine, but the process soon repeats itself.
What kind of wire do you need for an alternator?
Build and install a bridge wire, 14 gauge, one ring terminal on one end, one .250 wide flat female blade terminal on the other, from that large BATT term on the new 12SI alternator, to the number 2 terminal on the rear of the new alternator. If you have either a volt meter, or ammeter, you are done, finished, works like stock.
