Hello everybody

I'm working on a Jupiter 100H
The grippermotor does not stop
It takes a record and returns it without playing

Cancel-switch is working
Safety switch is working
Microswitch is working (tonearm)
Play-relay is working
Mute relay is working

Who can help me with this?

From your description and answers it's difficult (for me) to understand what steps in detail you did already.
Maybe you can describe a little bit more. I understand:
- All switches and relays were measured for being ok.
- All contacts and mechanical parts were cleaned, e.g. the cams can move freely and as far as they have to.
- All mechanical adjustments were checked.
- The circuits were followed, compared with schematics and checked.

I checked in a later manual. It gives these hints as well:
Cam switch C4 not closing.
Amplifier relay not operating.
Amplifier plug loose in power supply.

If still no success, in that case I hope another user can help better - and/or you follow again all circuits and adjustments given in a service manual.

Kind regards - Hildegard Stamann
