I am currently working on a 1997 m1078 with a cat 3116 and a wtec II transmission controller. When I flip on the master power switch, the lights illuminate as they should but when I press the starter button it sounds like the starter begins to turn over but then all of the lights/power go out. All of the batteries are fully charged but the voltage meter on the dash never reads higher than 24 volts in the yellow. After each attempt to start it the voltage meter will drop by ½ a volt. When I try to start again, I can sometimes hear a clicking noise in the direction of the power distribution panel (Sounds and feels like it's the K2 relay). Does anyone have an idea on what could be causing this?
I do not have starter M0017703MD that is listed in TMs, instead my truck had M0017705ME (I believe the one commonly used in CAT C7s) when I purchased it. I replaced all circuit breakers with fuses, I replaced a few bad relays and I replaced the auxiliary starter solenoid on the drivers side frame rail with a new one.
