[QUOTE="rblinton, post: 58269, member: 7948"] My 753G (1,700 hours) is completely dead. No lights, no indication there is any battery at all, but the battery reads 12+ volts. Last time running, the fuel / temp lights would flash several times with the ignition key removed, as if the key was turned on and off to the first (ignition) switch position. With the plug removed from the BICS panel I've got 12+ volts at the battery terminal of the starter switch - when the BICS panel is plugged in it falls to around 2v. There is continuity between all the pins of the 10-pin BICS & starter panel plugs with the exception of the ignition pin. I've inspected the wiring harness from the two panels (BICS & starter) to the back post of the cab and all looks good there. I can jump the solenoid and the engine turns over normally. I've inspected the main electrical plug above the battery and all the pins look very clean. The battery terminals have been cleaned. Continuity across the ignition switch positions appears normal. I'm thinking either the BICS or starter circuit boards are bad (there are no obvious burnt spots), and am looking for how to test them. Based on some other postings here, I see that Bobcats have an electric panel behind the seat? I haven't looked at that and since I'm 3 hours away from my machine I won't be able to until the weekend. I've ordered a repair manual from Finney but would greatly appreciate any tips if anyone has wrestled with an issue like this before. Thanks, Bruce [/QUOTE]
