Quoted from vid1900:

Here is a great diagram of the board pinout stolen from Tom Callahan.

On connector J1 I am missing a blue wire on my Lost World. Does this game not use two blue wires on the powersupply?

According to this J1 has two blue wires?

That is for Bally KISS pinball.

It's in the schematics. There is only 1 solid blue wire and that J1 connector is only 8 pins total, not 9 pins.
Please take a moment to learn how the wire color codes are marked.

No big deal. Just ignore the extra 9th pin on your board.

Turned on Stars and only had GI lights. Took the backglass out and noted the CPU power and test lamps were on solid.

Found the CPU +5volts was 4.2v and which comes from the regulator on the power driver board connected to the +12v which was pulled down to +10v.

After reading this tread, picked up new ESR meter and new replacements for C23 and C24. Meter confirmed both were shot, so replaced them and added the TP1-TP3 jumper, and back in action.

Thanks Vid, wherever you are.
