I manually ran every motor this morning and every column vended fine. The bill validator has power to and is blinking an error, according to what the lable says the error that states the following "vendor- credit empty". When I unplug and plug in the coin mech. the bill acceptor cylces. I removed the coin mech. and took off the front top piece, the one that removes by pushing up the two tabs at the top and pulls out from the bottom. After removing that I could not see any coins jammed. I dumped out enough coins to put the levels at half way to see if maybe it would help start vending again due to the fact it has lower coin levels, no luck. When I removed the front piece I noticed a red light on, not sure what that indicates but maybe that means something to someone. It really seems like the coin mech. is allowing power to pass through to the bill acceptor but none of its functions are operating correctly. It has been a really hot dry summer here and I thought that something would fail eventually but now it has cooled down, its odd that all the sudden it stopped now. This machined did though encounter its first rain since it was put back into service 3 months ago, maybe it got some moisture somewhere it wasn't supposed to. Thanks for the help.

I got the model number, it is a -MC 5800 DH- the serial number is -604-09875-, like I stated before the bill acceptor was reading coins only this morning but now it says nothing and will not pull a bill in. i tripped one of the microswitches on the machine and it will vend a soda. Now that i think of it should I have tried every row? would that make any difference? If a row was jammed would that prevent it from accepting money or vending anything else? If that were true though why wouldnt it still dispence change when I flip the switches. Thanks again for any ideas or advice.

UPDATE: I messed up, it is Mars changer, Dixie Narco bill acceptor USA 15, SORRY

I will get the model of the coinmech this afternoon when I go back there. When I showed up this morning the bill acceptor was saying coins only, the flashes on the bill acceptor indicated that the acceptor needed replaced. I unplugged it and plugged it back in, it cycled and then never lit up anything. it would not take bills and the change runs right through. Is it odd that the coin mech will not disburse the coins in the hoppers (nickels, dimes, and quarters. none work). I don't know, thanks for this help. I will get you the model this afternoon.
