dixmor led 7 voltage problem

[thetoms1]

I have a self serve bay that has dixmor led 7 timers and slug buster coin acceptors. As soon as 1 coin is dropped the timer tries to reset the display reads v.37 and will not reset it blinks as though its trying to restart. I checked the voltage and every time the display blinks I get about a 7 volt momentary voltage drop. I switched timers and coin acceptors and the same problem occurs. If I push in the mode switch the timer will act normal until a coin is dropped and then it starts all over again.
Any Thoughts? Please!!

Have you checked the voltage at the transformer while performing the same test? Possibly a bad transformer?

I have checked voltage at transformer and it only drops 2-3 volts during the event I have ordered a new transformer but I dont feel real confident that is the problem.

What happens when you take the problem bay LED7 to the good bay. Does it work ok? If it does, sounds like you have a short in the problem bay?

D e e problem timer works fine in other bays. I don't understand why the short only occurs after a coin drop. like I said if I hit the mode switch on the timer it all goes back to normal

Try Swapping transformers?

I have a new one I'm going to put it in later today
Thanks

If that doesn't fix it, I'm all out of suggestions. Let us know if the new Transformer fixed it. I can't say as I've ever seen a transformer doing that. Especially with just pulse load...It can't be much...

Have you swapped the coin acceptor to another bay?

Have you confirmed it's wired correctly?

It sounds like something is causing a dead short.

I believe you have a wiring problem. But try this, Disconnect the white wire that comes from the timer, this is the Timed Load, by disconnecting the White wire your isolating the timer from the rotary switch, drop a few coins into the coin acceptor and start the timer, if the timer works like it should counts down the Timer and coin acceptor are good. Are you using a new style harness or the old style? If you’re using the new style harnesses make sure the Yellow and White wires with the black tracer is not grounding out and the ends are taped. Also make sure the Gray wire is not grounding out the coin box. The Gray wire is not used with the Slugbuster coin acceptor on the Dixmor timer. The only wires used on the Dixmor timer with the Slugbuster are Red to Yellow, Green to Black and Brown to Blue, the Purple or Violet is not used.

Try unwiring the beeper... maybe a short bringing down the power supply...

I appreciate everyone's advice the problem turned out to be an internal short in the rotary switch. Thanks to every one for advice
