Bernina 707 capacitor?

The capacitor can be made. Og to www.syrep.no and make a request.

My 707 was blowing fuses. Examining the capacitor pack it had split and leaked and presumably gone short circuit. I contacted Bernina who said the capacitor pack was obsolete and no longer available and that the motor would work ok without it. I have now reassembled machine without the capacitor pack and everything works fine. It is not necessary to disturb the other wiring, just pull the capacitor pack wire spade connectors away from the terminals. If you are worried about the order of the wiring in case you accidentally pull the wrong ones off, just take a photo on your phone first.

It works! Same problem with older style 807. Bought two 0.1uF 500v capacitors from Maplins (£6.00 - the pack referred to above did not have a suitable pair of capacitors), connected in series, snipped off old capacitor to leave wires at full length, discarded earth wire (not required because motor is double insulated), stripped back ends of other wires and connected to the three capacitor ends. Had to guess which the middle wire was but the old capacitor connection was the clue.

Thanks for getting back on this one. I met a genius electronic guy who connected two capacitors 0.1uf 400v in series Got them from Maplins from a multi capacitor pack and attached them to the wires but leaving out the earthing wire from the motor body. Bingo the machine is back working properly. I am simply ecstatic and thought I should put this out for all long suffering Bernina machine motor victims

you right Ken,cant work without cap,i normally throw motor away and with small modification fit a universal motor,those motor are VERY hard to come by

If I remember the motor won't run without the capacitor, unlike all other makes that have a capacitor in the foot control
