Dumb question: Are the voltages right on all three phases?

Hi guys....if you know anybody that knows the control circuits for this transmitter, bounce this problem off them:

BE FM-30     the control system for the 20 and 25 is likely the same.

Problem:  3 phase main contactor in the power supply drops out, then immediately re-latches. 

It may not do it again for a few minutes, or it may do it 3 or 4 times in succession.

Again:  picture the TX in standby. All blowers on, filament on the PA.

The main contactor drops out, shuts everything off for a second, then latches back up.
May not do it for 5 minutes or so, from a cold start.  Very intermittent.

Talked to BE tech service last night...." Mike" gave me a list of maybe 20 possibles.  That's great.
I'm doubtful it is the contactor itself.  Something in the control to it is likely making it drop momentarily.

I am going to pull the front panel off the 30 today to access the OCR's and controls.  Or try to. 

Uncle G. in Lawrence.
There is no backup for it here.  Nada. Their money maker is down. 
I'll open up the transmission line today and see if I can get a spare 250w exciter into it with a reducer.
