@56g2000hsm.googlegroups.com:

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....

This is one of those situations where measuring the voltage with the system
not under load isn't good enough. If you have a poor connection, the
voltage will drop under load, causing the AP to drop off-line.

I know that my MasterView display can show system voltage and I believe
that was partially how I found the problem one of the times. I'm not sure
if you can display that on a ST6000/ST7000 control head.
