Hi all, working on a 873 . The coin accepted lamp and insert coin are out. Cleaned and checked the coin switches, wires at the hinge, zero switch, and the lamp itself, still cant get a response. where else should I be looking ,Thx

I always start with a known good bulb. Then I work backwards. The Molex door plug has been the guilty party on more that one occasion.

if the door plugs seem ok, does the winner paid lamp work?
if not, the common factor to all those lamps is a payout relay switch with yellow wire 30 on the long/moving blade that connects to orange/red wire 71-2 when the payout relay is unpowered. Could also be hopper plug issue.

I would check normally closed switches on hopper pay relay located at rear of hopper. Also check beau plugs on back of reel mech and hopper. The wizard.

Schematic for a 1090 machine might help as basic operation circuits are similar.
But not in all cases.

schematics for a few different 873 models are on https://bingo.cdyn.com/slots/
david's 1090 schem is pretty much the same except the coin unit on a 1090 is the line unit on an 873.
