Thorens motor runs backwards!

GhettoSQ · 15th September 2006, 11:00 AM

Hi all,
My TD160 motor occasionally spins backwards (well, maybe more than occasionally). the Analog Dept. says this can be a tired motor or faulty input cap. Does anyone know how to check?
thanks!

Hi,

Oil the motor, if that doesn't work change the capacitor.

/sreten.

My TD166 occasionally does this. It did if from new too. I guess it is down to the design of the motor (syncronous).

...I vote motor start cap

FWIW -- I give my Thorens a spin in the correct direction -- it sits right adjacent to the computer workstation, is quite ancient, and in almost constant use.

OT -- must have been designed by the same engineers who worked on my 500E wagon -- the rear wiper works bass ackwards. Maybe it was after lunch on a Friday that they assembled it.

one phase of the motor seems to be burned - check both windings

Nope, it would only twitch then. Then there is "that" smell. You know the one. Hard to miss.

I'm convinced your Thorens is possessed !
Undoubtebly you will hear devilish lyrics when playing in reverse.

I should dig out my old heavy metal stuff! LOL!

I've tried giving it a push, doesn't seem to matter, it either plays right or doesn't. I hadn't thought of oiling - could that really cause this?

so, two votes for the start cap...someone else fingered the resistor. I'll take a look at the electronics and maybe try to the cap this weekend.

thanks all!

Hi Jack,

is that when you look in the mirror or from your anti world?
