Hello
Having an issue with adjusting the reverse switch on my R. Mech stopped reversing a few weeks ago, and noticed that the reverse switch spring was broken. Replaced with another spring of another switch. Unfortunately that did not fix the not reversing issue. Tried adjustment per the manual and per the overcenter switch description by Ron but no luck.
At this point think I need a replacement switch as maybe the contacts are worn beyond adjusting?

Hi crm,
Does the motor still move in the other direction if you first move the motor back manually? It may well be the swich contacts but could also be a wiring fault, for example something like a poor connection, maybe even at the reversing switch?

I closely watched what is happening when it's at the end of travel and the motor is definitely not switching direction. Consequently its "bucking" against the stop. If I interrupt power with the service switch or main power switch the motor will stop then go reverse like it should.
Tested the reverse switch with an analog VOM and it appears to be working like it should. No loose wires to the motor.
Several months ago replaced the motor capacitors with new plastic ones. Going to test them...perhaps one failed? All motor connections look ok nothing loose. I may pull the motor and inspect it closely.

The motor capacitor is definitely a possibility. Also make sure the 'O' contacts are making correctly (and in good condition) on the 'cam switch'.

Does the motor reverse if you manually operate the reversing switch mid travel?

It will occasionally switch direction when I operate manually. More often it will just continue in the same direction

If it doesn't switch mid travel, that would look like a faulty switch to me! In simple terms, the motor has two windings; AC is permanently connected to one winding (with the capacitors), the AC to the other winding is swapped by the reversing switch initiating rotation change.

Think I finally figured it out. Last year the original motor capacitor failed. I replaced it with X2 rated poly caps. Worked fine until recently. Both caps tested well below their capacitance. Replaced with some other poly caps I had on hand and seems to be reversing without issues again.
Can't remember where I bought the X2 caps. I know it's not really there intended application. Is the motor current killing them? Should I use a different type?

That's interesting! Jukebox parts suppliers normally have suitable Seeburg motor run capacitors. It is possible to cobble together an alternative though, there is a wide selection of motor run capacitors available for domestic appliances should you wish to take a cheaper option - but they have to physically fit! If the capacitors you fitted last year have failed, then the suspicion would be that they are not fully rated for that application.
