AZVendor Posted February 26, 2015 Share Posted February 26, 2015 Welcome to the forum cshisler. I'm sorry you own a Gaines machine and now you're finding out why we don't recommend them to vendors. Not that other validators don't also fail, but the imported ones fail at a high rate and can be difficult to find replacements for. Your issue is probably in the validator itself, but possibly in the logic board. Link to comment Share on other sites More sharing options...

cschisler Posted February 27, 2015 Author Share Posted February 27, 2015 i replaced the validator with a new unit. the original unit was flashing a red led and would not accept any bills. the new dba is accepting bills the system as indicated doesnot register the credit .

DeanEnterprises Posted December 1, 2015 Share Posted December 1, 2015 Hey Guys - Did you ever find out the solution to this? I, too, have a Gaines 750 A that won't accept register bills but coins are working perfectly. Thanks, Brittany ** Moderator note, duplicate post deleted.

cschisler Posted December 1, 2015 Author Share Posted December 1, 2015 no was unable to get the unit to work properly. picked up a bill changer on Craigslist for $75.00 that was small enough to actually bolt on the side of the vending machine. all is well now.

Good idea! Any idea of the make and model of the change machine? I may explore that option. I have a whole Gaines vending machine im parting out if you need a part I'm not opposed to it. Is it a 750 A or B? Any idea as to which part it is that would solve my problem? Link to comment Share on other sites More sharing options...
matthew0582 Posted December 2, 2015 Share Posted December 2, 2015 750 A or B what is the difference? Ill have to check. Tell me what part you want. I dont mess with those machines, I just have one to part out Link to comment Share on other sites More sharing options...
