[C320-list] FW: Battery charger/inverter

[Pat Kenefick]

Karl:

Charger - Flyback 20-3 - Flipped it on the other day , noticed electrical 
"burning " smell ; shut it off ; turned on today to check and it began 
smoking - needle went up 20 AMPS ; do you know if  when they "die" they 
smoke or is it an indication of a short or some other problem ? I would 
assume this one is dead now, but I wonder why - was it old and just time or 
some other problem ?
Any ideas ?
Thanks
Pat K
