Question

My camper van is over charging when it is on main hook up over sixteen volts the unit fitted is scheiber ref 633120 can you tell me a unit that I can retro fit on how to stop it over charging

Answer

Any stand alone battery charger will replace the charging function. If you have digital read outs or lcd displays on your control panel you will need to fit a genuine charger as a replacement if you want these to continue working. I have put a link to the battery chargers below.
