International 9200 suddenly won’t crank

[rtjohnson1982]

Hey everyone, I’ve been fighting a sudden issue with my 07 International 9200 for almost a week now and am at a loss on what’s wrong. Long story short, truck has always cranked just fine and fired it up last Tuesday morning no problem. Got to customer after driving a few hours cut it off and it wouldnt crank back up. When I turn the key to accessories it reads about 12v on the gauge and radio,cb, etc power up fine but when I attempt to crank it loses all voltage and will barely turn over once if at all. So far I’ve replaced all four batteries, starter solenoid, and all the ground and jumper wires in the battery box. Currently checking and cleaning the connections at the starter but any help/advice would be VERY MUCH appreciated! Between buying parts I may not
need and downtime, it’s getting expensive. Thanks to any help or guidance you may have.
