I have the capability to fix anything on the charger, just don't think its cost effective to ship both ways, and if its the transformer (non switching type) it is not cost effective at all to fix.

See if there is an electronics repair shop around you if it isn't simply blown fuses.

Battery Charger - I had luck on ebay
 

FYI, I found a great charger on ebay for $40. It is a Charles 30A 3-bank charger with 3 stage charging. The seller had pulled it to convert to a charger/inverter setup. While a little overkill for my 27' Laser, it is the same unit that was factory installed in the 29' Enticer and 31' Tiara I used to have. Nice part is these will not overcharge and they can supply loads on boat when plugged in at a dock. I think new they run about $300-$400.

Marine battery chargers
 

I was looking for a battery for my motorcycle and ran across this site, which has a good selection of chargers:
