Installed new starter
One on truck was turning slower and slower.
Starter has been on truck since I bought it from GP and it was new(ish).
Replaced solenoid when first got truck. Been great.
Thought it was battery’s at first, but the Hawkers tested and load tested just fine.
Both alternators good.
Wiring all good and physically checked.
GPs are new and GP relay is new also.
Thought maybe GP card at first when it was still turing over decent. Just wouldn’t start hot.
SS member AntennaClimber sold and sent me two new ones. Turns out I don't need them right now. Spares!!
When truck would barely turnover, slaved to the 5 ton, I figured the starter.
Great to have a spare starter on hand.
Sure enough, it was starter.
Installed new one.
Wow!!
It spins engine over faster than I ever remember.
Reading the TM troubleshooting and old threads helped, as always.
Will take old starter to shop for rebuild.
