I just picked up a PP for $50 today that runs perfectly through the qualifying round, but resets automatically every time the green light hits on the actual race. I also realized that if it's not on free play, it'll reset when trying to coin up. It looks like someone has already done the 5v mod to it. I know that PP are generally cursed, and it'll probably be a mega pain to fix, but I thought I'd ask for ideas?

Thanks in advance!

Sounds like a problem with one of the program ROMs. Either the roms themselves or an access issue. One of the CPUs is getting lost and the watchdog is barking.
 
Do some reading on the Pole Position: This link is not really about your issue but it has links to manuals, shifters, and some wires.

After that there is usually more info at the bottom of this page.

Voltages are very important but that game has all kinds of problems with connections that can cause voltage changes and burnt connectors.

There is much info here on this subject but I always start with the power supply to the boards and the power to the chips.

For $50 and partially working pp you got a great deal. Now you will have some money to put into the repairs.

That was my initial thought when the guy told me what was wrong with it, I thought I'd ask before I dug too deep. I just reseated all the roms and voila, works! Thanks guys!
