Hi,
I have just acquired a coin mech and credit board for my MAME project. When I try to connect it up the I-PAC I seem to get a continuous credit signal, in other words, the credits are flooding into the game without even inserting a coin!
Just wondered if you knew what the problem could be? I bought it in working order from a reputable guy on ebay.. It's a Sentinel coin mech but not sure what make the credit board is..
Any advice is much appreciated!
Kind regards
Gareth

Id check to make sure your ground and hot wire aren't touching. Also theres a little lever on the side of the coin mech that moves down when a coin is inserted. Make sure thats not stuck down. If you need to check put a quarter in while watching the side of it, if nothing moves than youre thingy is stuck down.

Are you sure you wired it to the opening prong and not the closed one.

Sounds to me like he got some ELECTRONIC coin mechs, not your standard ones.
GWOOD, you may have to give us more info (model #, pics?) and maybe a reason why you opted for electronic over the simple mechanical variety.
The IPAC is designed to receive coin input as a simple "button" switch closing. Each time it closes, that's one credit detected by whatever game MAME is running. There is no need for a "credit board", unless by credit board we are talking about an optical coin switch?
Either way, check as was suggested above, that your connection must be set up in a "normally open" way, not "normally closed".
