Initial symptoms were that the boom/bucket would lock out, seatbelt light would come on, resetting the seatbelt would turn the light off and bring boom/bucket back on line. Absolutely no other indications of a problem. In researching symptoms everything pointed to failed seat or seatbelt switch. Replaced both, no change, it had been a few days, so I checked battery for charge, 1.2v, this is when I found the battery up against the frame with both terminals literally melted away. New battery installed, had to jump the starter to get it off the work site, thankfully the boom/bucket were still stuck up in the air, or wouldn't have been able to get it off the site.Issues found so far: Altenator burned out; replaced. Additional Actions Taken: Replaced 15 amp, 6 amp breakers and starter relay, Seat and seatbelt switches seem to be working properly, ie, light goes off when both activatedProblem: will not start from key, CAN start by jumping starter relay from battery, but no boom/bucket controls, also there are no lights at the logic module, could the logic module be compromised?Any help greatly appreciated.Thank you</blockquote>
