Hoping someone can give me some good insights into my Revenge From Mars. I just got the machine a week ago (yep! Super-thrilled!), played at previous owners and it worked/booted up just fine. But when I got home and had it all re-assembled, I get the "Coin Door Open" error with all 50v parts disabled, etc....
Wah-wah....the thrill of playing is on hold! Argh!
I found that one of the leads from the Coin Door Interlock to the 'tabs' on the back of the switch had come loose. I tightened it up and replaced, but that still made no difference. Still 'Coin Door Open' error.
I have done a couple of the basic checks (e.g. backbox ground braid attached), but one of the first tests I've done seems to be a major clue, so looking for some guidance from anyone here who help!
When I tried a continuity test on the leads (spade connector tabs?) on the back of the interlock with the door closed (as shown in photo below) I do NOT get a continuity signal. I'm not an electrician, but it seems to me with the switch closed, there SHOULD be continuity, right?
As confirmation that this might be the problem, with RFM powered up and the multimeter leads applied to the spade/connector tabs on the back of the machine, the 'Coin Door Open" error message goes away and all the LEDS light up - looking like the error was solved.
This seems to tell me that my coin door interlock switch is bad. Does that sound right to any one with an RFM or more knowledge about these Bally/Williams pins?
I assume I can probably get a new one, but before I do that, I wanted to know what the consensus is on the fault and my discovery of no continuity and proper boot up when the tabs are 'shorted'? There are some less obvious tests or checks that I can investigate, but I feel like I found the issue right away, but what do I know!?
Thanks in advance for any advice!
