Combines 860 Alternator

Seedman I dont know if you have fixed your problem but we have a late model 760 that does this occasionally . We can park the thing for a month and it will start ok then for no reason at all it will flatten the battery overnight , and I mean FlAT not a squeak out of it. I gave up and disconnect the battey every night .

Hey, this sounds like a design flaw, I have given up trying to find electrical leakage when shutdown of all machine for the past 5 years in my 860!!!. Have been just disconnecting at end of day, probably safer anyway if you developed a short overnight somewhere in system. I think the short is somewhere in combine monitor_warning systemIJIJ The BEST solution is to buy a "Kill Switch" from Caterpillar dealer and install. These are standard issue on most newer Cat implements.
