Hi Paul, I have a KiloVac EV200AAANA contactor with 'economizer attached', so does not need a diode The board is powered by a small auxillary battery which is charged by the DC-DC converter.

Q1 seems okay, but I might try replacing it and the optocoupler U9 as well after I get them from a local electronic component supplier. Any idea what the voltage readings should be at U9 and Q1 before and after precharge?

I have sent Adam the cvs files I saved when I tested the cold controller earlier today.

Amin
