SORRY WE NO LONGER REPAIR MOTOR MOVERS
Most of the issues we encountered with Motor Movers were from a poor battery. It is important the battery is a Starter based battery, not a pure Leisure battery.
A pure Leisure battery is not designed to deliver the kind of current drawn by two Motor Mover Electric Motors, which are generally larger than a car Starter Motor. The Leisure battery suffers degradation that then overloads the Charger unit.
Note we do not sell batteries.
The quality and age of a battery on a Caravan with a Motor Mover is key to the life of all the Electronics in the Caravan.
We strongly suggest you use only a quality Wet Acid battery, not Gel or AGM, that will better handle the high current draw without overheating over extended periods caused by a Motor Mover, some of which can draw 160amps from the battery.
