Hello there. Having a few issues with my M1008 CUCV. Recently had my GEN 2 fail on me in both power generation bearing life. When it went out it took my batteries with it.
I've replaced both batteries, the GEN 2 Alternator, the Glow Plug Solenoid/Relay, and the Doghead Starter Solenoid/Relay.
Unfortunately, i'm still getting issues with the system. The glow plugs do not seem to be activating, but they all seem to be in good condition. Each still lights the test lamp when grounded. Also, there seems to be an intermittent overcharging issue. The overcharging is more pronounced when the engine is operated at a higher speed, and less so at lower speed.
The voltage readings are as follows:
BATTERIES
Front - 12.89v
Rear - 12.88v
GEN 1
Red Exciter Key Off/Plug Out - 12.89v
Brown Exciter Key Off/Plug Out - .02v
Red Exciter Key On/Plug Out - 12.7v
Brown Exciter Key On/Plug Out - 12.6v
GEN 2
Red Exciter Key Off/Plug Out - 25.7v
Brown Exciter Key Off/Plug Out - .07v
Red Exciter Key On/Plug Out - 25.7v
Brown Exciter Key On/Plug Out - 25.3v
GLOW PLUG SOLENOID/RELAY
Top Key Off - 12.88v
Upper Key Off - 0v
Lower Key Off - 0v
Bottom Key Off - 0v
Top Key On - 12.7v
Upper Key On - 12.3v
Lower Key On - 12.5v
Bottom Key On - .007v
DOGHEAD STARTER SOLENOID/RELAY
Red Key Off - 25.7v
Purple Key Off - 0v
Purple/White Key Off - 0v
Black Key Off - 0v
Red Key On - 25.6v
Purple Key On - -.001v
Purple/White Key On - .005v
Black Key On - .005v
Any insight in to where I should start looking?
