M998 Alternator Question

[kvoyson]

I am finding myself in need of a good regulator. I have the kind that looks like a Starburst. This will be my second replacement. The brushes looked good previously when I had it open and I blew everything out. It worked flawlessly until it quit altogether. Now its 24.3 on or off, it has voltage to the exciter. Last one was a ebay NOS. Not sure if China or not but it didn't last long.

If anyone knows a good economical source please let me know the name.

Which regulator are you looking for? I have a new on off a 60 amp

That power comes from the EESS or PCB box.
All this is pretty clear on the schematics
There is a relay in the box that powers the wire #5 that excites the alt.
EDIT, #568 is only used on the 60A.

I decided to go a different route.
