I am curious to know if anyone has had a similar problem.




Got a voltmeter to measure the voltage supplied to the control head and
motor drive? Still sounds like corrosion is causing intermittant power
interruption to one of them......or low voltage from dead house batteries.

I believe it shuts down on low battery voltage....
