I am new to all this stuff and have recently aquired a very nice Tempest. It worked fine last week but now when you power it up, the screen and start buttons flash on and off. It is set up to take quarters but won't register any credits. I can mess with the credit switch and get it to show a credit occasionally and it will start playing for maybe fifteen seconds and then go back to the start screen with no credits showing. Any ideas?

Thanks
 
First check your voltages on the board, and adjust the ARII voltage if needed. Next check the connector going to the coindoor, I've had problems with poor connecting pins on those molex connectors a time or two.

The other problems with Tempest are the interconnect cable, these are notoriously bad. Also re-flow the solder on the header pins for those cables. I forget who sells repro but you should consider getting one JIC. Typically the cable will solve alot of problems.
