When I score over 100,000 points on my 1973 Williams Gulfstream, the 100,000 point light does not come on.
The light comes on if I manually move the 100,000 point relay.
I have good continuity between the 10k point score wheel and the 100K relay.
The M-30-1300 100K coil measures 25.4 ohms. A coil chart listed it at 26 ohms.
The 10K score wheel mechanism seems fine, lifts the contacts at 9.
With the game on and >100K points, I have good continuity between EOS switch, 9th position switch, and 100K coil power but I am not measuring any voltage at the coil.
I cleaned all of the switches and contacts on the 10K score wheel and 100K point relay.
Manually activating the 10K score wheel switches does nothing.
Based on the manual (p 21) it looks like the reset relay ties into the 100K circuit so I cleaned those contacts. No help.
I have attached the relevant area of the schematic.
Here is the manual http://mirror2.ipdb.org/files/1094/Williams_1973_Gulfstream_Instruction_Manual.pdf
Anyone have any ideas? What's my next step? I'm tagging pin-it B/C you helped with my 100K problem on another machine. TIA, Greg.
