I have a th6x4. One day it wouldn’t crank, we use it daily. After jacking around I have positively confirmed the ignition switch is good. The signal wire was bad so I ran a new wire and now the start relay clicks. I can run a wire from the battery to the signal terminal on the solenoid and it cranks. I get full volts through the signal wire when unhooked but it reads like 54v when hooked up. I don’t get what the 54v comes from? And I ohms tested the solenoid ground back to the battery at 4.2 ohms. What is going on??
