[Shop-talk] schumacher SE4022 battery charger

[Dan Fest]

I have a fairly new schumacher SE4022 battery charger.  It's a good quality
one for trucks, etc.  We were using it the other day and it was working fine.
While in use, we heard a click and it stopped working.  Is anyone familar with
these ?? Does it have a circuit breaker of fuse ???? I'd like to try to fix it
since it cost almost $350 last year.
thanks,
Dan
