Motor Mover

Does this problem happen everywhere? We have problems with ours but only at our storage facility, it cuts out and won't work unless you stand close to actual unit and at first the we thought it might be the battery but it happens after a trip as well when it's fully charged and it's fairly new at under two years. No such problems on a site. 

We were puzzled but we have since found out this occurs with some others, there is mobile phone mast very close and one possible theory is that it is interfering with the remote signal in some way? 

We certainly had that problem with our power touch motor mover at our storage compound. There was clearly some sort of radio interference, particularly under certain atmospheric ( high pressure ) conditions. Like you it did it when the battery was fully charged and started working again if you stood close. We get a linked issue now with the tracker in the MH. Again particularly when high atmospheric pressure, as lately, I get a warning that potential jamming has been detected.

Power touch do seem to be susceptible to interference even between units. A couple of times on sites when someone close has been using theirs at the same time, ours has cut out or theirs. As soon as one party stopped using it, the problem went away.

That's where my money is, since I had exactly the same situation with the Powrtouch mover on our last van. After a very helpful conversation with Powrtouch, they were looking towards a faulty battery but when I pointed out it was almost brand new, they agreed to send an engineer out to check. He eventually found that the post connecting the negative leads between the two control boxes hadn't been tightened up enough (a common problem according to him) and as soon as it was tightened up again, it was fine. Because of the high current draw, it doesn't take much for resistance to build up and prevent the system working.

I don't really think I can be as specific as that, since how the wiring is configured will depend on who did the installation. In my case, there was a threaded stud with a flange that allowed it to be screwed into the floor and the negative leads from each control box were connected there - and thence to the negative supply from the battery. The leads were secured with a nut - and it was that, that was loose. It was an AWD motor mover - hence two control boxes - in your case, you will have just one pair of motors and therefore one control box. (By 'control box', I mean the blue rectangular box of tricks with the flashing lights on top that will be secured to the van floor somewhere - not the remote control!)

All I can suggest is that you work your way methodically - from the battery to the control box, to the motors and check that all connections are really tight - using a spanner / socket as necessary.  Don't just assume that if it seems hand-tight - it's OK - because that was the problem with mine.

Hope this helps.

I too have exactly this problem with a Powertouch classic on my Swift Challenger 480. It was OK when put away last year, now it runs for 30 or so seconds and then stops, restaring for another 30 secs. or so when switched on or off.  All terminals are secure and clean , the battery is new and fully charged reading 13.2v on my both my  multi meter and the caravan control panel. I have also replaced the 9v cell in the hand set !

I shall be very interested to hear what solutions others have come up with .
