Coin mech works in one machine but not another

[dr galaga]

I had a Mars TRC-6200 coin mech in my Vendo 63.  I put this in my Cavalier CS-80C and the mech acts dead.  It returns anything you deposit and if you flip the swithes to empty the coin tubes, nothing happens.
The Cav. originally had a Coinco S75-9800B in it.  This works fine in both machines.  No, putting the Coinco in the Cavalier is not an option since I need to put it in the Vendo.  The Vendo is going to the employee break room where my wife works and the Mars only accepts nickels and dimes!

Any idea why the Mars will work in the Vendo, but not the Cavalier?

Anyone have a Coinco S75-9800B they want to get rid of?

I'd check for a loose wire...weird that the coinco wouldn't work but the mars would....

I see you have found a replacement, but as to your question. The only reason I think it could be is there is a slight difference in the wiring (maybe a 3-wire connection as opposed to a 2-wire connection) or a different model switch or solenoid. Maybe a pin on the plug is wired in one and not the other.
I am by no means an electrical Einstein, but it is two different manufacturers - times two!

You can buy a coinco on ebay for less then $50...in my opinion thats the best way to go concidering that some of the sellers even guarentee it

That's what I was thinking.  I need to find a manual for the Mars.

Does the mars that doesn't work have 2 sets of dip switches?  If it has the extra set of switches you may want to try sliding #6 to the other position. Does it have a larger switch labled Cigarette one way and Standard the other? if it is in the Cigarette position try changing to the standard or vice versa.

Some early single price mars mechs had these switchs so they would work in machines with a vend relay.

It's been awhile since I have worked on these mechs so I don't remember what models had these switches.

I can only see 2 sets of DIP switches.  One set for pricing and the other for exact change.
Are these the ones that you can program different coins?  It would be great if I could get this thing to take quarters.  Someone even wrote Nickel and Dime Only in marker on the side.  The date stamped on this is 1994.
