How I wired my alternator.

[garyd1961]

I rewired my alternator today. I wired it the way VetteVet showed in post #2. My ammeter still doesn't work but It seems to be charging ok, 14.4 volts. I don't believe the ammeter gauge ever worked since I had the truck, bad gauge maybe. Even if the gauge doesn't work the alternator should still work ok shouldn't it?

Yes, the alternator / charging system will still operate correctly even if the ammeter is not working. If you wan to get the ammeter working again, start by checking the condition of the 2 inline fuses that are shown on the diagram VetteVet posted. One of them is located over near the battery on the passenger side of the engine compartment and the other is on the driver side (near where the external voltage regulator was originally located).

They are both 4 Amp fuses. If your trucks still have the original rubber case fuse holders (as shown below) they take SFE-4 fuses.

Thanks Ray! This is a big help I don't think they are still there will check in the AM. If not I can replace them with inline 4 amps. Thanks again.
