older IVS/Doyle vacuum issues

[BrooksCarWash]

I have an older like late 90's IVS vacuum. I put three new motors on it and it worked for a day or two then stopped taking quarters. So I bought a new sensortron coin accepter and it still didn't work. So I bought a new timer a Ginsan GS-402 which was what was in it. And it still doesn't work.

Does anyone have suggestions on what I could have done wrong or what could be wrong?

Have you checked voltage?

Get out your volt meter and start checking the power from were it comes into the vac, to the transformer and to the timer and to the coin acceptor.Does the vacuum have a mercury relay or any other type relay?

Based on the failures you've noted and the parts you've replaced, my guess is you have a bad connection to or from the transformer, or the transformer is bad. I'm assuming you have a transformer because you replaced a GS-402 part for part. A GS 403 has a tiny transformer inside that powers a coin acceptor.
