Hi
We have a 1991 Coachman and the 12V Charger/Transformer is blowing the 240v 2Amp fuse as soon as it is swiched on.

It is a Logic 1 charger, does any one have any ideas or experience of this fault?

Thanks

Jim

It is one of a few things.

Most likely is a shorted rectifier on the secondary side of the transformer, or the transformer itself has a shorted turn or there is a smoothing capacitor short circuit.

Probably repairable if you can find someone to have a look at it, where are you based?

If you get stuck, give us a shout, we are in NN10 and we manufacture large chargers for the railways etc., but happy to have a look at it if you want to pop by.

Forget it, the logic1 was junk when new, nevermind now!

Due to the uncertainty of the wiring in your van, perhaps your best option is one of the Aldi/Lidl 3.6amp chargers, only £14 when on offer and this is at least 3.6 times better than that logic1, even when it worked!
