Help - 2610 won\'t start, suspect Voltage Regulator
Had the tractor out last Saturday and mowed for about an hour, shut down and when in to eat lunch and there was a brief rain but when I went back to the tractor a couple hours later it would not turn over. Tried to jump the battery but no luck. Got the voltmeter out and the battery showed about 12.8 V DC. Checked all connections at battery, starter, alt and everything looked tight. Started playing with things and noted that sometimes the charge light on the dash would come on when I turned the key to on and sometimes it would not. Left the tractor alone until the next day (last Sunday) and checked it out again. Turned the key to on and the charge light illuminated, turned to start and I just got a click or clunk from the starter. Turned the key back to on and no charge light. Repeated a few times with the same results. Let the tractor rest for awhile, turned the key to on and got the charge light, tried the turn signals and they would flash but the draw eventually killed voltage and the dash charge light went out and turn signals stopped. Let tractor rest and signals would do same again, let rest tried headlights and immediately killed voltage. Tested throughout the week and found the tractor would maintain the signals and eventually the headlights but would not turn the starter. Tested the VR (that is the small cylindrical unit attached to the top of the starting motor, where the positive lead of the battery attaches, right?) with a voltmeter. With voltage at battery at 12.8V, voltage across VR was 12.7V with key off, dropped to 11.4V with key on, and voltage across VR would slowly drop when turn signals where turned on, more quickly when headlights were turned, and immediately drop to zero when tried to start. Let tractor rest for 10-15 minutes and voltage across VR would go back to 12.7V but would drop again as previously described.
Does this sound like a bad VR? If so where is a good place to get a replacement? Do I need to get a factory part from one of the tbn dealers or are there crossover parts that will match from say NAPA or JD?
