Battery charger fuse replacement
I need to replace an internal fuse on an old Motomaster battery charger. The fuse is a solder on glass fuse and the only mark I see on it is SB 658. The only info I can tell about this fuse is it is a "slow blow" fuse and I have no idea of the amperage. The charger is a 6A charger so I am wondering what type and size of fuse I can use to replace it.
Should I solder on a fuse holder or buy a fuse with axial leads and solder it on?

This would be the type you have now.... 215 Series-5x20mm Cartridge Fuses from-Littelfuse

That is an automatic resetting circuit breaker. Not too many in use anymore.
That is in series with one of the battery cables..... correct ?
There are items to replace it but I don't know what amperage to tell you to use. I have bins full of parts like that and I'd try one experimentally. You want a breaker that holds for charging but trips on a short or overload. I'd be tempted to start with a 6A part.
In the link below is one place to get it from.
SHORTSTOP Circuit Breaker 12VDC 6A - $1.25
Let me know where it's installed first or take a picture a little further away.
