Everything was working fine yesterday then yesterday afternoon all of a sudden the gen 2 bulb is no longer on or off, but dimly lit.
Here is what I checked:
Front Battery Engine Running: 14.32 volts
Rear Battery Engine Running: 12.42 volts, (gen 2 is not charging)
Alternator exciter plug:
Key off:
red: 25
B/w: 0
Key on:
Red: 24.8
B/w: 24.5
24V gauge in the cab: 24.8
I did rebuild both gen 1 and gen 2 with the spring hill kits a month ago, I though it was easy and had no problems.
What would cause the bulb to glow dim? It happens when you turn the key on and stay dim with the engine running. Gen 1 comes on bright and goes off on start.
If you unplug the gen 2 prong exciter wires the dim bulb goes off.
Any ideas?
I replaced the 194 bulb on the Gen 2 socket and same thing, dull bulb.
