The yellow wire shown in the above should be tested for continuity before unsoldering. If it’s ok, try the following:
1. Check if there is continuity across the AC power prongs using an ohmmeter. If not, the transformer is bad. That was my problem.
2. Check that the pencil actuated switch closes properly when the pencil is inserted, using an ohmmeter. Clean the contacts if necessary.
3. Check that the small shaving tray safety switch closes when the tray is inserted. It’s actuated by a tab on the R rear of the tray.
4. Apply 12V (AC or DC) to the two yellow wires. If the motor runs, the diodes and motor are ok.
5. Apply 12 VDC to the motor directly, using the two terminals that the black capacitor is attached to. Make sure to attach the negative side as marked on the capacitor, or you might blow the diodes. Use a power source that can supply at least one amp.
I will gladly donate my unit with working motor and good gearbox to anyone that asks. Add a w in front of firstname.lastname@example.org
