I’ve used this 6x6 for several years to feed my cows. Coming out of the pasture the other day it wouldn’t restart and acted like battery was dead. Would not jump off my truck. Pulled it to the shop, battery checks good. Turn key I hear fuel pump but won’t crank. Jump the two posts on solenoid it cranks bit no fire. Checked break pressure switch and it tested good. Been scouring forums for a couple of days and have run out of ideas... I think I’ve narrowed it down to a bad ignition switch or bad solenoid but don’t know how to test either, and don’t know what else to check in the event the solenoid ad ignition switch are ok. All help/ideas are appreciated.
