Ideas on what to check?
Thanks!

Per the diagram, seems I shouldn't have power to the rest of the truck, if the ammeter were open. And if the it were just the ammeter open, seems I should still read some output on the alternator, itself.

Good callPwrWgnDrvr wrote:Ammeter is fine. It is telling u the system isn't working. Most likely regulator, but can be alternator too.
Test by running a wire from the battery + terminal to alternator field lug. If ammeter does not show a massive charge, then the alternator is bad. If it does, then the regulator is bad.
Not sure how the hacks to the original wiring would affect this, since I only see half of the schematic. I dont consider the hacks an "upgrade".
Yep, that's exactly what I've ordered. Once it's up and charging, I'm going to figure out the previous owner's hack.my5thmopar wrote:Upgrade to an electronic regulator. I got one on fleabag in the old style case. Voltage is rock study. Craig
It looks to me like the Red 27 wire from the ammeter feeds the fuse link into 16 block. This protects the circuit that feeds the splice and onto the fuse block and ammeter. What's not shown in the FSM is the Black # 16 wire from the splice going onto the other side of the ammeter. If the black 16 wire does go onto the ammeter there would be a small amount of current flowing through the ammeter. Without it there, no current flow through it. What do you think?riffraff wrote:Good discussion of the proper upgrade in this thread. Looks like terminals #16 and #27 should have been jumped, in my case. Going to have to see if my under-dash wiring has been buggered much.
Edit: trying to figure out what good the depicted 16 to 27 jumper is. Seems it would just bypass the ammeter (like I have now). Hum.
