SNV no coin / Bill signal

[Earl Weiss]

Cloeman SNV

So, my acceptor stops accepting. Replaced many. Rather than try to re - weave wires I cut the old ones and join to the new with wire nuts, Y to Y B to B, and RGs to RGs. easy peasy.

Well, did something dumb. Cut wires with power on. Blew 24 Volt fuse. Replaced fuse and acceptor. Accidently knock plug out of bill acceptor. Plug back in.

Now bill and coin acceptor accept coins and bills, but no signal to timer!

It's not the timer since if I swap another from a working unit, same issue.

Tried to make sure connections I made were good. If I disconnect or reconnect yy or BB with power on timer acts like it just got a single coin signal.

So, what did I knock loose? HELP!

Try unhooking the bill acceptor and test it with coins. It sounds like the bill acceptor signal output got fused closed.

What is a "Cloeman SNV" I've never heard of that piece of equipment? If your using a IDX MA-100 or X-10 coin acceptor there is no need to cut the wires when you replace the coin aceptor you can slid up the door on the side of the coin acceptor and unplug the wiring harness from the coin acceptor. Try unplugging the bill validator from the system, you might have fried the board inside the validator.

It's like the dyslexic atheist who doesn't believe in the existence of DOG.

Tried it. Same result. Acceptor takes coins, Timer does not register them.

It doesn't sound like there's anything left to be the problem except the coin acceptor.

Well, that would be a heck of a coincidence for the exact same issue with the Bill acceptor taking Bills but no signal to the timer.

The wiring inside the unit is hard to trace. I was thinking of making Jumpers for the Black and Yellow to the timer, but I do not know what timer terminals it would be.

I am guessing that somehow where the Black and red meat the harness along with the Bill acceptor coin signal wires, from that point something is loose.

It's not really a hell of a coincidence if you realize there is no signal sent to the timer. The coin acceptor and bill acceptor simply short out an input voltage that is native to the timer. That means if one of the outputs is shorted it will hold the imput low and no credit will be seen by the timer from either the bill acceptor or the coin acceptor.

Well, then it would seem that by only connecting the coin acceptor if the Bill acceptor was bad then it should work or vica versa. Tried the first but not the second. I doubt the coin acceptor is bad because it's new.

Stranger things have happened. It'a a carwash, after all.

Earl,

With our adventures with lots of different coin mechs ... I will try to explain what I would try to do to isolate the problem. The wire that switches the timer should show on the schematic if it switches to ground or is actually positive voltage. At that point I would try to come up an led setup on my workbench & see if it flickers when the bill or coin acceptor switches whatever the timer schematic or ladder logic diagram says it should.

Dan is much more of an expert than me when it comes to the inner workings though & the need for precise crimps etc. I know one time I had a mysterious connection problem & by soaking the unpowered terminal connections in vinegar ... a bad connection was permanently corrected.

I hope this helps .... mike

Don't have a schematic for thhe Coleman Timer. I think it's a 1034 R. If so I would just jump the sih\gnal wires direct from the Coin Mech and see what happened. (Tracing them is a nightmare)

Update: Met today with my distributer's tech installer. Installed my first Units 20+ years ago.

Tried everything I did. Installeed new coin mech, Isolated coin mech by disconnecting bill acceptor, Swapped for another timer from another working unit, re strung wires from coin mech to harness, Same result. Mech takes coins but no signal to timer.

He will call Coleman Monday for words of wisdom.

Met agian with Distributer installer.

To recap, while changing coin mech that would not accept quarters I cut the wires to it without killing the power and blew the 24 Volt Fuse.

Replaced fuse and put in new mech. Unit would take coins and bills but timer would not register a signal from coin mech or bill acceptor. Swapped timer with one form a FNV and had same issue.

Tech came and swapped out mech. Same issue. Again tried swapping Timer. same issue.

Tech comes back with New mech and timer.

Replace both an issue solved. Now getting signal from bill acceptor as well.

So it seems. Original mech bad, 2 rplacement mechs (1 his and 1 mine) both NG, and Timer was bad.

Live and learn what to try next time it happens.
