Tankman 3,523 #1 Posted May 28, 2013 The 520 is runnin' like a clock, forget the "idiot" lights. Charging at 14-16 volts (per the gage). When I turn lights on, volt gage drops to 10-12 volts. Doesn't however seem to do anything. Should I investigate? Necessary PM needed? :smile: Share this post Link to post Share on other sites

Save Old Iron 1,571 #4 Posted June 1, 2013 tankman, check the battery voltage with a multimeter see if it matches the response of the tractor voltmeter Share this post Link to post Share on other sites

Save Old Iron 1,571 #6 Posted June 1, 2013 i'm guessing the battery will not change by 2 volts under headlight load. If you use your multimeter to measure voltage present at the tractor voltmeter (any pink wire) and your multimeter reading agrees with the tractor voltmeter reading - then corrosion in the 25 amp fuse holder, ignition switch wiring and the 15 amp fuse holder would be the likely suspects.
