Purchased a comet because I got it for a great price and the playfield is in excellent condition however I’m not a big fan of this game thinking of taking it to the local eagles club and renting it. One issue I am having is the 1 million award is not working. When you light it up and land the ball it does not score 1,000,000 not sure what’s going on with that

To be sure I took the Glass off and manually triggered the 1986 lights and manually trigger the million rollover it does not work however the million rollover switch works and scores when it’s not on the million light

Earlier I posted about my Comet power CB with a loose Molex connection that had been previously "Repaired" by someone that "threaded" wire to the board through the molex.
It didnt last.
Wires were broke and machine was cutting out.
I have since repaired it with new pins and a new molex connector (purchased at Frys-found perfect mate!)
See attached pics of step by step repair.
Machine works great now except the dunk the dummy drop target doesnt like to drop when hit hard and straight on which is disappointing.

OK I WENT BACK AND RE UPLOADED PICS CAUSE THEY WERE IN WRONG SEQUENCE....NOW THEY ARE STILL IN WRONG SEQUENCE...START AT BOTTOM AND GO UP...

Tech help needed.
My lower GI lights (behind stand up targets and lower bumpers) are not lighting. All other lights work correctly any games plays as it should with the exception of if I leave it on overnight the next morning the displays are all blank and I have to do an open door reset but then it plays fine except for the column lights being out. I checked voltage and there is nothing at the lamp sockets. See pic of CPU board I J7 connector.
The manual describes this as lamp column output. Resistors are hot to touch and there are burn marks on the board. I checked the back of the circuit board and its clean, however resistor 111 appears to have been replaced or soldered on before.
The manual says it is a 26 Ohm 2-watt resistor I ohmed it out and it is reading 30.1 All the other resistors are all reading right at 26 except R 101 which reads out at 30. How much tolerance should there be do you think this may be my problem with the lights not working or should I check something else

Really? that makes complete sense to me as that has been the case on my other machines and I respect/appreciate your advice, however see pic of comet MPU pinout (IJ5-IJ8) and that's where I have the burnt resistors...this game has a strobing /flashing light effect that also controls GI lighting 9at times) so I can see where the MPU would be involved.

Wayout 440 and Brewninja I want to thank each of you for sharing your knowledge I was checking for DC voltage and checking the wrong place see attached picture of the correct GI lighting input and output jacks you can see the output Jack 3J8 is burnt. I cleaned the terminals put it back together and now my GI lights all work! This happened after I have been leaving the machine on at all times I am going to start shutting it down when not in use. Like I do with my e m games.
I am using incandescent lights would it be wise to change to LEDs or do I have to change my power supply or solder a bunch of damn resistors on each socket?
THANKS AGAIN YOU GUYS ROCK!

yes, I have already repined and replaced with a molex a connector before. At least I have some experience there, cause it looks like I'll be doin it again...
Thanks again guys!
