When the motor is switched on, it sort of jogs its way round in a back and forth motion, but overall in a reverse direction.
Please see the attached pictures of the motor/motor pcb, and the board it attaches to (power board) I can't see anything visually wrong, and the Service Manual I've downloaded isn't helping me much.
I only have a digital meter (no oscilloscope etc), so fault finding is difficult. I'd like to check the output voltages on the 7 pin connector first, but can't see this in the manual. Or is the fault more likely to be on the motor/motor pcb anyway, so I should concentrate there first.
Maybe replace all the electrolytic capacitors as a first step??
Thanks, Rob

Electrotanya has a better manual than vinyl engine but its still 3 big chips operating it in block diagrams .
If the fault isn't the mechanical start switch connection then without an oscilloscope on a crystal controlled DD motor then all you can do is test voltages at the chips.

Don't run motor without aluminium platter. When you run motor without platter, it will run back and forth and sometimes reverse. Put on platter and check.
