Power touch mover problem

Hi my power touch mover has started to drain the battery in seconds, I checked connections and ran it without it being on the wheels it starts ok then in a few seconds the voltage drops quickly to 9.4 where it cuts off . The battery returns up to 12.7 and if you switch the mover off and back on it works again but a few seconds later the battery drops again until 9.4 and cuts out again.

The caravan is plugged in at home and reaches 13 volts when unplugged.

Both battery and mover are 4 year old a year within their guarantee, any ideas please

    I would suggest that your battery is failing.

    Can you get it properly tested?

    If it's not the battery, then there's probably a dodgy connection somewhere.  I had a similar problem with our last van and when the engineer turned up he found a loose connection on the post that the negatives from both control boxes were connected to. I know you said you've checked the connections but I'd have another look - all the way from the battery to the motors.

    Remove your battery and take it to a tyre/battery supplier and ask them to carry out a load test on the battery, this will then ascertain if the battery is faulty. Good luck.

    A battery will show 0v if its terminals are short circuited (not a good idea because the shunt will get very hot very quickly). The load imposed by your motor mover is considerable, though most definitely not the same as a short circuit. But the mover load will cause a lower voltage when it’s working. Electric motors create their highest load when stalled, with a decreasing load if they are able to run freely. Your mover’s motor may be restricted in its rotation due to a lack of lubrication, rust or a number of other causes. You might do well to run them without touching the tyre, by way of a diagnostic test.

    My guess is that the battery is at fault.
