Having electrical problem with Ford 1920.....see www.tractorbynet.com/forums/parts-repairs/264468-ford-1920-electrical-trouble.html I checked for more mice chewed wires....couldn't find any. When I turn the key to "on" it blows the fuse for the "quick start timer and voltage regulator circuit." I disconnected the timer, blew another fuse.
I then took some voltage readings:
tractor off, battery voltage: 12.5v
tractor running, lights off, battery voltage: 12.2
tractor running, all lights on, battery voltage: 11.95
tractor running I got the same readings at the alternator.
From what I've read, the voltages with the tractor running at 1500rpm seem low. What should the output be at the alternator?
Since the voltage regulator is internal to the alternator, can an electrical novice (me) test it?
Would a defective regulator cause the fuse to blow, since that particular fuse protects the voltage regulator circuit?
Any and all help apprecuiated.
