This charger has no blade fuse, as far as I can remember, so what is your Absorption voltage set to?

If everything is set up right, maybe your charger is just broken...

How did you change it? You did it yourself or had to send it back?

As the unit was out of warranty I changed it myself.

The fuse is a 50 amp fuse (100/30) soldered to the board (looks like a very little midi fuse)

Be careful when taking the lid off as the stuff they use to seal the unit is stuck to the top a of the lid
