I just want to say all the functions worked in the bays before I opened them.  I check them once a week and really never have problems.  I just should not open the doors.

It all started with a coin jam.  Someone really beat the crap out of it and the coin acceptor came unscrewed.  I also replaced my broken in-line fuse.

I then tested the bay and the spot free did not work (purple and black wire).  I did not know where the wire connected so I opened another meter door.  Bad mistake.  Now high pressure does not work on the second bay (second picture).  Also, this red wire snapped off (third picture). 

I believe my problem is the wires are corroded and seem very brittle.  Also, the terminals seem rusted.

So I opened the third bay to fix the second bay.  Again bad idea.   You get the picture.

Someone beat the screw out of the Max-Vend II support.  The top of the brace has two screws holding it in and the bottom only has one. Why?

I am not blaming anyone, but before someone disconnected the coin acceptor, only the acceptor did not work.

First the little yellow wire from the equipment room was pulled out.  Maybe a ground or something to the timer?  Next picture another little yellow wire to the coin acceptor was pulled out.  The rotary switch had multiple loose wires which I tightened.  Also, one fell off the switch.  Last picture was the little white wire for the spot free rinse.  This wire was broken in two.  But the meter box is so small this could always be a problem.  I need to purchase some cheap meter boxes and throw these away.

The last problem was on a different bay.  The fuse decided to totally break.  I need to replace the fuse holder.

The problem was the wire harness came out.  I checked all the functions and everything worked fine.

One of my IDX coin acceptors was doing the fast green and red blinking.  William said that is bad news.  I am not surprised that another one broke.
