Again can SM905 be repaired as timer cannot get past 'notches'?

As with other's, my acl switchmaster sm905 timer will not go round. The timer works in twice mode but not in once mode as timer cannot get past the notches. We need to replace with same so can fit wired backplate (or can others fit?)

Seems no one can answer - can you?

Thanks

this will need re-wiring.....

You should find that you can buy a compatible replacement for the SM905 which should slot straight onto the existing backplate.
If not providing you make a note of the correct wiring combination it is not that difficult to replace the backplate as well as the timer.
