You have got a 4 price changer, which only allows 4 different product prices in the machine with a maximum price of .75 with all dip switches in the on position. It appears that you have a 10 price control board installed. Set up 4 different vend prices on the switches, starting with your lowest price (ex. .50) on the No 1 switch and put the next higher price (ex. .55) on the No 2 switch and your next higher price (ex. .65) and the last one (ex. .75) . This will make it easier when you set your board.

To set board to selection prices:

If you want selection A to vend for .75, you will move the A switch to price 4 on board.
If you want selection J to vend for .50, you will move the J swith to price 1 on board.
If you want selection T to vend for .65, you will move the T swith to price 3 on board.
After getting your prices set you can run money through the changer while counting it to make sure your prices are correct.

Give it a try and see what happens. If this changer is compatible it should work. Hopes this helps.

I haven't been on the internet for a while, but was able to try this out last night, and it worked perfect. Thanks a lot for the help. Much appreciated.

I uploaded a couple of larger photos here

and here

hopefully that will help.

I get the idea of setting the prices by the coin mech (mostly) but changing them individually is what's got me stumped and that's the only reason I can figure for the extra switches. I know they work (at least where they are set in the picture) they just stop working when I change them.

I'm not much of vending machine guy, but I have done electronics work for some time.

The first thing you need to do is check and make sure that you have the machine plugged into a designated outlet with nothing else running on it. 9 times out of 10 in situations like this, I go into a house or business and find out that the a/c or frige is popping breakers because there is a microwave or something on the same circuit. This would explain why it worked fine at first, but then started tripping later on.

Also, make sure the breaker running that receptacle has enough amps. You make have a 15 amp breaker on that circuit and need a 20. Same with the GFCI.

If these are not the problem, then it is most likely a problem with the relay that starts your compressor. There is no way for me (or anyone else) to know for sure without actually being there. A relay is pretty inexpensive, however, if that turns out to be your problem, but -word of warning- relays going bad are sometimes a symptom of a bad compressor.
