Not a Mopar But Ford Electrical Question

Thanks, I will try that tomorrow. I do know that last year when I was having issues with this damn thing, it would keep melting negative terminals on the batteries whenever I would try to start the damn thing. Never did figure that one out, one day it just started working right and ran and drove it several time last year to cut hay and boom, this year it pulls this crap. I can't afford 50k for a new swather and keeping all this 40 yr old equipment running is getting to be a pita.

The Terminal Voltage does read 12.xx volts, until hooked up to the cabled on the Swather, then it dies to 0 Volts. Will check it again tomorrow.
