Powrtouch mover

[Mark_374318245]

Hi all, I bought a second hand twin axle caravan in 2015. The van is a 2006 Compass Rallye and has been very well kept. It has a Powrtouch mover on all 4 wheels. Its an auto engage hand set operated and up until recently has been fine. I had a problem with the leisure battery so bought a new one last year. 115amp. recently after engaging the mover its been cutting out. moving only an inch or two but in that inch or two its been drifting off to the left. I thought that I may have bought a duff battery but after seeing something on a forum I tried just spinning the rollers without them attached to the wheels and I note one is not turning. I'm therefore assuming that if it does not turn its sticking so thus cutting out the mover.
I've emailed powrtouch and hope they will get back to me. Do you think it will be an easy fix. Anyone had similar in the past??

Changing the battery should not effect the operation of the mover, unless you have dislodged a connection somewhere. If all connections are OK then there is likely to be a control unit fault.

Thanks for reply. all rotors are connecting to the tyres but one roller is not turning so I suspect it to be the motor on that wheel. what do you think

Hi Mark
Have you changed the batteries in the hand controller?
Have you checked all wires are connected at the control unit?
Have you checked power is reaching the control unit?
If yes have you checked power is reaching the actuator mechanism and the motor?
Please let us know the final solution

hi, I have not done wiring checks as I'm not skilled in that area and I don't have the equipment but the hand set works as it is turning 3 out of the 4 rotors so I'm assuming its a fault on that 4th rotor

Time for a Powrtouch engineer B)

just got off the phone to them. their tech department are gonna call me back

 

[Mark_374318245]

Tech department rang me and asked me if I have a technical rubber mallet and if so give it a whack while spinning the rotors. Well it was like a magic wand. The rubber gators are split so I'll get some large cable ties to hold them together. Happy days folks

AH! The rubber mallet the must have tool in everyone`s toolkit B) B)

Sounds like the motor brushes have stuck in their guides..
This is a common problem with motors of this type, it can be an indication that the brushes have worn down to so much that the spring applying the pressure are at their limit. If it happens again I suggest giving the motor a clean up and new set of brushes.
You don't need the hassle of pushing a ton and half of caravan around!

By replacing the brushes early can save wear on the commutator.

 

[Mark_374318245]

Is that a complicated job.

 

[GD485]

I was talking generally about motors of the type used in a motor mover. I suggest you get in touch with manufacturers and ask if they can supply motor brushes. Some motors are designed in such a way that brushes cannot be replaced easily. The only way out of this problem is to change the motor.

Noted and many thanks

Here is a link to powrwheel on changing brushes.

Nice one Cheers

The spade connectors on the motors can get dirty as they are near all of the muck. Wriggle them about and see if this clears the problem. If so fit the cables with new crimped spade connectors.

 

[Mark_374318245]

Just blinking snapped one. Will have to get crimping plyers and connectors now. Well at least 1

Bought a pack of 10mm female spade connector off ebay. All fixed now. Cheers everyone.
