I now remember that I had put a white and black jumper in J2 so that I could test out the power supply. So I removed those jumpers and plugged that male power connector into J2. Now back to my original problem, I still have no power. No lights and no sound. Where to start. Any suggestions? --- End quote --- It looks like J2 goes to the interlock switch and the power switch. Both of those could cause no power to flow to the rest of the cab. --- End quote --- I missed that - so the mystery of J2 has been solved :) Jennifer - the wire nut part is where a panel mount fuse holder should be - that would also kill power to everything if that was screwed up. But not likely since power has already been measured down stream. (However - I'd get the proper holder and return it to normal) |

The mystery of J2 was solved long ago. Also there is a proper fuse holder where the power comes in. All is good there as well. We're at J5 now where the voltages don't match up to the schematic. Did my 7 pics that I uploaded this morning not show up? 10,12 is showing 102.5 VAC, should be 60 VAC. Pins 11 and 13 are blank, no wires or metal pin. Pin 15 on the underside of the power supply has a green wire that is fastened to the chasey. I wonder if there is anyone out there that could verify these pin configurations. This game did work properly at one time with this configuration. I'm still thinking that a winding on the transformer went bad. :) |

When I get home from work I will measure some voltages for you on my machine. If you are getting voltage at J5 your monitor should be receiving power. I think it is pin 10 and 15. I will double check that when I get home. |
| Mike A:
Here is what my original schematic says. Pin 10,12 should be 100VAC 11 and 13 are blank. pin 15 is earth ground. |
