New to this (engine repair), but willing to try
anything...I have a MF1855 that is having an electrical
problem. Basically, if I put the key in the "On"
position (not started), the amp meter pegs to the
left and the breaker trips after about 10 seconds. I can actually start the tractor, but once the
circuit is gone, it dies. I've try checking every circuit I can find, and
come up with one clue. If I unplug the voltage
regulator it runs fine. I then tried unplugging
the alternator (leaving the VR connected) and it
ran fine as well. The alternator is buried in this beast (flywheel),
so I'm still attempting to get at it. Anyone have
any clues as to which replacement part I should
order? Any way to check it via the two wires that
come from the VR without removing the alternator? If I check the continuity, should I see some
resistance? Infinite resistance? If I check each
to ground, should I see some/infinate resistance? Thanks in advance.
