call stren to get the parts,you can look them up on your computer.i had some problems with mine 2 weeks ago,same problem with spinner plate working loose from shaft.they have had problems with all there units doing this and they will send you a new unit at no charge.they have made some inprovements to the new shaft.as far as wiring the units if they tore the wiring up,you should be able to do this yourself.i took my feeder apart to change the motor and was surprised how simple it was to work on.there is not alot of wiring in the unit.
