Hi everyone
Happy New year!
My drill charger stopped working and it looks like i have a dead “thing” (i think water got in it)
Can someone tell me what this was so I can fit a new one?
Thanks you

 

Some kind of fuse, 3.15A 250VAC.

 

Agree. It appears to be connected to the AC in.

Thanks both
What do I need to get? Could i just fit a jumper?
Regards

hi nick,
Check on the back of this RED box area, it looks burnt out, 3.15Amp fuse.

Thank you Eric
Is this the sort thing?

 

hi nick,
That is the correct fuse rating.
Has the copper track on the other side of the PCB been melted away.?
Usually, when a fuse/component has been destroyed, that badly indicates a short circuit elsewhere in the circuit.

Hi Eric
I will check, but i think water got in it.. for the sake a few pounds its worth a punt

Use an ohmmeter and check for continuity across the fuse.

 

If the fuse is shot, there is a good chance the thermistor and MOV are shot too. You should test them before connecting a new fuse. If either of those are shorted and you jumper the fuse, things might get exciting for a moment.

And I think a fast blow fuse would be the proper choice with that MOV (what looks like an MOV anyhow). Slow blow fuses are for big transformers that might have residual magnetism opposite to the polarity present during power on or other situations with momentary large peaks in current. A battery charger like that probably doesn't eed a slow blow, and it might even cause damage down the line the next time that MOV fires and can't blow the fuse fast enough.

Can you tell me which components you are referring to? I will order new bits.

Thank you

I have checked those 2 and all OK.. However there were 2 blown solder points on the component on the heatshield. It has 7 connections. I resoldered the connections and powered it up. The battery charge light is on, and a battery seems to be charging. So far the fuse has not blown. (yet)

 

Thanks for the update.
Good luck...........
