I am repairing a Williams Grand Prix and have it mostly working except for an issue with the 500 pt relay
Hitting the advance (L or R) bonus target does the following:
1. The 500 pt relay pulls in and the score motor stars turning
2. The 100 point reel does it's thing exactly 5 times
3. The 500 pt relay does not release and it keeps pulsing the 100 reel
Any ideas what might keep this energized?
Quoted from Mopar:or maybe magnetized
relay plate
Ding ding ding ding, we have a winner! I went to check this out and it started scoring when I pressed the credit button. Turned it off and found the relay still held in.
Great catch
