Can I Repair This - Golf Trolley Battery Charger

[Turtle Shed]

Hello all.

Wife plugged in her Motocaddy charger and there was a bit of a bang. Please see below. I think the yellow thing, which I assume is a capacitor, has failed in a fairly spectacular way.

I am well aware that the whole thing could still be carrying a charge, and I won't be touch any connectors, but I'd love to repair this rather than fork out £60 for a genuine replacement.

I don't mind buying the bits and soldering them in, and I don't even mind if it goes bang again, but the components will be cheap and I like to repair things if possible.

Any electronics hobbyists/experts think that there's no harm in giving this a go at fixing? Or is there likely to be far more damage than is obvious and I'd be wasting my time?

Cheers all.

Looks like a X or Y class capacitor, mains rated. Not much to lose trying a replacement. You should be able to clean enough soot from it to read the values etc.

There's a fuse underneath that heatshrink next to it, I'd check that too.

Cool, cheers.

I’m guessing it’s a Rifa X2.

Need to replace with another X2 capacitor for reasons below:

Be easier just to buy any other 12v lead acid charger for £13 (Aldi, for example) and cut and splice the caddy connector on the end.

This assumes you don't have a lithium battery.
