jmwenda0115 Posted June 20, 2013 Posted June 20, 2013 I have a Maka 11NB-400 and it is not accepting dollar bills. i tried and replaced the belts on it as this seemed to be the easiest and cheapest fix. It doesnt even attempt to accept bill. When I reset machine, the dbv cycles through. not sure what to do.
mission vending Posted June 20, 2013 Posted June 20, 2013 Its not worth fixing, get a new harness and replace it with a mars DBV. AZvendor can hook you up with what you need at a fair price.
AZVendor Posted June 20, 2013 Posted June 20, 2013 JM, I hope you didn't pay for belts due to it never trying to take a bill because if the transport motor never starts when a bill is inserted, that has nothing to do with the belts. The noise you hear is the validator powering up, but it may not be communicating with the machine. This could be a comm problem in the validator or it's inhibited by the machine. The first thing you must check is whether there is enough change in the coin tubes. You need 12-15 coins in each tube before the validator will be enabled. If the tubes are full you should try another good coin mech to rule out a bad tube sensor in your coin mech. If you don't have another mech to try in this machine you could remove the validator and try it in a different machine with a similar interface. If you confirm the problem is not caused by the coin mech then the validator should be replaced. I don't recommend putting any money into any of the metal validators anymore as they are very old now and the hard parts for them are getting scarce. The older they get the older their gears, electronics, switches, etc. are getting. You will be much happier with a late model validator from Coinco or Mars. There are very few machines that will only work with a Maka so you should be able to upgrade it. If you can give me the model number of your machine and of your coin mech I will know what fits properly in your machine.
jmwenda0115 Posted June 21, 2013 Author Posted June 21, 2013 Lektro-Vend Model # VS99B SERIES 2 Coin Mech Coinco 9302-L
AZVendor Posted June 21, 2013 Posted June 21, 2013 The 9302L coin mech is not commonly used, but you will find it used in many USI machines. You must use only a 12 pin 24V coin mech in this machine. A Mars TRC6010 will also work in the machine, but not a 6010XV. If you have a good Coinco 9302LF you can remove the board covers behind the acceptors of both Coincos and swap the harnesses between the coin mechs so that your 9302LF will become a 9302L. Then you can test the new coin mech in the machine and see if the problem is in the coin mech. If your replacement mech works after swapping the harnesses, then be sure to change the model number of each coin mech so you don't get them confused. Mark the 9302L as an LF and mark the 9302LF as an L only. As far as upgrading your machine, Lektrovend generally included a bag of parts that would allow the operator to put a Mars validator in the machine. Do you still have that bag inside the cabinet? The validator harness that powers the Maka will usually power a Mars validator too, with one minor change. If you have to upgrade I will fill you in on that.
jmwenda0115 Posted June 21, 2013 Author Posted June 21, 2013 ok i'll try and swap the coin mechs and see if that fixes the issue. thanks for your help.
jmwenda0115 Posted June 21, 2013 Author Posted June 21, 2013 I have verified that the coin mech i have is working properly. my guess is i need to replace the Maka bill validator then. anyone?
jmwenda0115 Posted June 21, 2013 Author Posted June 21, 2013 Would A Coinco Mag50 Bill Validator be compatable to my lektro-vend vs99b machine?
AZVendor Posted June 22, 2013 Posted June 22, 2013 It's possible but you would need a pigtail harness to change the Maka plugs to Coinco but the Coinco bezel is different and it wont fit the door. There is a likelyhood that the machine won't be able to communicate with the Mag50 either. The factory harness will work with a Mars VN2501 and possibly a Coinco BA30SA but again, the door wasn't designed for a Coinco validator as they weren't manufactured when the machine was made. The reason the VN2501 fits is because it's bezel is the same configuration as the old VFM was, so the upgrade is always to a Mars VN2501.
EddieMac Posted August 19, 2014 Posted August 19, 2014 I have two USI 3129L snack machines. The MAKA 27v validators are going bad in both of them. What can I replace them with??? They both have 15 pin coinco coin mechs in them. Neither is MDB. Thank you all for your time and information.
AZVendor Posted August 19, 2014 Posted August 19, 2014 I'm surprised that you have Maka validators in any HR32 snack. Those machines usually had Coinco's from the factory. The easiest upgrade is to go to Coinco validators as they will only require the validator and a pigtail harness to convert from Maka to Coinco. Are your Maka's black NB14 models or something similar? I can provide these parts if needed. Just send me a PM for information.
AngryChris Posted August 20, 2014 Posted August 20, 2014 I have two USI 3129L snack machines. The MAKA 27v validators are going bad in both of them. What can I replace them with??? They both have 15 pin coinco coin mechs in them. Neither is MDB. Thank you all for your time and information. I did some research on this and I found some interesting things. First of all, a quick google search of your problem showed me a previous post you made about 2 years ago for the same problem. Secondly, from my other research, your MAKA validators appear to have a modern bezel on them that allowed them to be mounted in a standard bracket for modern validators. This is good if it's true because it means your 3129L has the same validator bracket as any other 3129 and can mount modern validators such as coincos and mars. What I don't know is this.. how exactly does your MAKA connect to the machine? If you could provide pictures of the bezel (from the inside, showing where the bracket holds the validator on the machine) and the connections (all connections from the validator to the board), we could probably figure out the best way to fix this problem. Also take a picture of how your coin mech hooks into the machine as well. If the coin mech is MDB, and your validator bracket is standard, your machine can be upgrade very easily!! Chances are someone or some company thought MAKA's would be better (or cheaper) or they ordered the machine with no validator and installed their existing MAKA's with a special bezel to save some money. I feel pretty confident that you have the proper bracket AND an MDB harness coming out of your machine. Take pictures of all of your connections and mounting bracket! I bet your machines can be upgraded from those old MAKA's to something pretty fancy for the cost of a 24v validator! You will probably end up spending $150-$200 on each validator and it will probably take you 10 minutes to take the old MAKA out and put the new validator in, and your machine will work like never before AND probably bring you some more money!
AZVendor Posted August 20, 2014 Posted August 20, 2014 The HR32 models were built with full face openings for any validator to mount in. He also said he has a Coinco 15 pin changer which will be a 9302L. The Maka will have a 4 pin inline power connector and a 2x3 pin credit line cconnector.

I didn't read that part about the 15-pin coin mech. The only reason I asked is because, if he already has an MDB harness, or if he has an MDB coin mech, he's probably ready to go! I didn't see anything in the manual that showed a part number for an MDB harness but I don't see why it wouldn't be possible to simply buy a new MDB harness and upgrade everything.
AZVendor Posted August 20, 2014 Posted August 20, 2014 This machine has the F80 board which is MDB capable. The machine might have an MDB harness hanging in the door and it would also have a Coinco MDB connector on it, but since he's running micromech in it now, I doubt the MDB harness is there.
