No insert lights on a pinbot.
Power is very low when connector j4 (power for lamps from power board) is plugged in 1.6v.
When j4 is unplugged from cpu power gradually goes up to 18v.
As far as I can tell 18v comes in at j4 goes to a c78, c77 (.1mfd 50v cap) and L3 (inductor) before going to the lamps associated transistors.
Anyone run into this before?
