Jungle 500 Pts Scoring 100 Pts Gottlieb

Hello,

I am in the middle of my first EM restoration project, a Gottlieb four player Jungle. The issue I am running into is that whenever I trigger something that scores 500 points (rollover, standup target, or the 500 relay itself) the score motor starts, you hear one clear *ding*, and it scores 100 points. Very rarely it will actually score correctly, seemingly 1 in 100 tries. Looking at the 100 point relay, I observed that it pulled in for the whole motor cycle, never pulsing. I have cleaned and adjusted all the contacts on: Relay D (500 Pt Relay), Relay M (100 Pt Relay), and 1A on the score motor. The error occurs on all four players. I also noticed a small (original to the machine?) jumper wire between the last switch on 1A to the last switch directly above it. Not sure if this is suppose to be there or not. Any help would be greatly appreciated!

BTW I have the schematics.

Thanks!

Does the 100 Point (M) relay release when the 500 Point (D) relay does?
Does it do this for all 4 players?

If the 100 Point relay never releases and it only holds in for 1 player, check the End-Of-Stroke switch on that player's 100 point score unit.

Yes the 100 relay does release at the end of the 500 cycle on all four players.
