Powrtouch mover

[Paul cope]

Has anyone had an issue with only one side mover only working , I have checked to see if there is voltage on both motor's which there is but only the r.h roller is working. Not sure if it's a mechanical issue with the l.h side,has anyone got a mechanical drawing of the unit

The only issue I come across is stuck brushes on the motor's commutator if this is the fault with the system off measuring across the motor terminals on the base unit will show high resistance compared with the good motor which will be about 0.1 ohms .Clouting the motor with a mallet (not a hammer) may release the brush. The brushes are accessed once the cover is removed and are held in plastic holders(see photo) , which you press and slide the cover off. You may find a 'lip' on the carbon brush or they may have simply worn away or just grim build up - clean the brushes and slides with small toothbrush -don't use grease when reassembling as they require good electrical contact with the slide. check for low resistance on the terminal spades and if OK you can test the motor by running it. New brushes are available online

The Trudgians also do a video of changing the brushes
