No output from charging system.
This tractor has a 12 HP Tecumseh engine. Stator under the flywheel checks out fine....AC voltage is 20-28 Volts from ~ 1/2 throttle to WOT. This is fine according to Tecumseh manual.
DC output is 0-2 volts on a digital voltmeter, zero on an analog one.
Manual is unequivocal....rect/reg is tostitos.
I am choking on the OEM cost ~ north of $150-.
It is a 10 Amp stator, 20-28 V AC input. Simple two wire in one out config....neg. ground, solid state unity.
OEM was REPCO FG-4720 B, Sears part number 672R.
Two questions:
1) is there any witchcraft here, or should I be able just to find and substitute a generic unit that will fill the bill? Could I find a separate rectifier and then use an auto regulator?
2) Would a 15 amp unit BE ok? I have found a John Deere part that seems like it might work. PN AM33845.
Thanks.
