Christmas Tree Lights - 1HZ

[athensrep]

Put in the new brushes and rectifier. Still lit up dash. Disconnected the glow system - still with the lights and not charging.

Looked at the fuses and I have three missing? What in the world? Glow, governor and ECD? PO pulled them for some reason?

Possible that your model didn't use them?
I see from the wiring diagram that all those dash lights are wired together with protective diodes...
I suspect that you either have a poor ground connection somewhere around the alternator, or else maybe there is still water in the relay box.
Can you find the charge relay and remove it, and see if there's any change?
Your ignition fuse is good?

Im just digging back into it as the parts came from Dubai this afternoon. I’ll take your lead and see if I can use your suggestions in the AM. I didn’t think of this not having those fuses, but maybe you’re right.
Thanks for the reply.

Are there metal terminals inside the fuse block to connect to a fuse? If yes, no harm in connecting them to see what happens.

No, they’re blank fuses. I got hopeful too soon.

Fuses are all good under the lock panel on drivers side. Batteries are good. Unplugged glow relay as it’s clicking every 10 seconds and no change. Unplugged harness to alternator - no dash lights of course, so I assume wiring is good there.

Edit - did a diode test on alternator. Tested good. Unplugged GP relay as well - lights still on.

I’m wondering if this is a ground issue? But the alternator would still charge, correct? Just not efficiently.

If you don't have a solid ground then the diodes might cause all your lighting issues, and if they went out when you pulled the alternator harness then that points to the alternator and it's grounding I think.
Did you find the charge relay and pull it?
Water in electrics is usually most disruprive on small signal wires like ECU and CAN bus connections.

 

[athensrep]

No, I haven’t pulled a charge relay yet, but thinking either grounding or fusable link? I’ll look up location.

I order a used alternator from Japan to test as it was cheap. I have a suspicion this is the issue as there is a distinct electrical burnt smell omitting from mine. We shall see.

Occams Razor…figures.

Alternator came in today, swapped the VR and the brushes in, cleaned it up a bit and slapped it in. No lights. No clicking glow plug relay. Charging at 27-28V.

I did inspect the old one and there is some corrosion on one of the diodes. Also, there is a sweet, burnt smell - hard to describe but resin-ny.

So, hopefully my stupidity helps someone somewhere. It was just the alternator - I guess the stator is burned up? Diodes tested OK so I don’t know.

On another note, I have a couple brand new 79 series 12V alternators laying around that are the same casings, etc. as the 24v. How many parts are swappable? I found conflicting info on being able to swap in a 24 Vr and it working but what about amps?

Thanks for all the responses.
