It has a Danfoss oil pressure control on the pecker head. i must be missing something any words of advice for a young chiller mech.

The last one I had do that the HP switch was opening before it was suppost to You can watch it with your guages as it revs up

I found a bad connection in the pecker head of the 06E comp. It was on the high pressure switch. One of those factory wire nuts that are crimped replaced all of the wire nuts and unit has cycled several times without incident.
