Harlem Globetrotters On Tour
Bally, 1979Hi!
I recently got a harlem and suddenly upon booting, all inserts lamps are out. I tried moving the connectors on rectifier board and they all lights came on temporarily but then off again. Can anyone help pinpoint what connector/wire on the rectifier board is the one feeding power to the insert lamps?
I would believe i need to repin the connector responsible..
20200123_184411 (resized).jpgConnector J1 on the rectifier board goes to the playfield.
The blue wire at pin 7 is the playfield feature lamp power which is the one you want to look at.
Generally you should probably re-terminate the wire crimps on all the rectifier board connectors..
The insert is powered from the J3 Backbox connector
Are you talking about the GI lights? Those are marked 7v AC on your diagram. All the solid color wires are for lamp power. Solid Blue is for the switched lamps.
The switched illumination lights are labeled 6v DC. They get their grounds from the lamp driver board.
Is the picture the old or new board. Wiring looks pretty good but I see a lot of cold pin solder connections.

It was insert lamps not working. First picture is of old board which was ready for retirement. Second is the new board, although somewhat unecessary photo. 
But all works now!
