My 89 4x4 trail boss wont start. When I hit the start switch the solenoid just clicks. Battery reads 12.3 volts, Solenoid to battery terminal reads 12.3 volts. Solenoid to starter reads 4 volts after pressing and holding the start button, I don't think thats right but hopefully someone can clear that up for me. How do you test the circuit breaker, I split the pouch hoping for a giant clear fuse and be able to just look at it but that wasn't the case.
