Positive and negative backwards? If yes your battery and charger are junk. If no just your charger was bad when new.

Maybe this page will help, you have to download the manual.

Anybody know how to take one of these apart to replace battery? I removed all visible screws,but apparently there are some hidden ones

I have the same one. The black wire from teh ac cord has a white connector that goes on the switch but there are 4 choices. I need a diagram as well.

the wire at the clamps might have came off,there is a thermal fuse inside the charger also, get one at the auto parts store .bring the old one with you. OR some of the newer chargers are fussy that the battery must have some power to get the charger to turn on.. i use jumper cables to get my charger started..
DID I HELP ? VOTE . THANKS J

Some of these chargers are automatic to the point of aggravation. They will only operate when they are connected to a battery with at least a small residual charge. Not sure if this charger is one of those. Try hooking it up to a known good battery. It that works, and you are trying to charge a dead battery, first use jumper cables from a good battery to the dead one for a few minutes. Then hookup your charger to the dead battery. That should give it enough charge to prime the charger into working, and you could then remove the jumper cables.---- but be careful!!! wear safety goggles.

try taking the battery out, make sure the ac adaptor is not connected, hold down the power button for 60 secs and then put the battery back in and try turning it on.

Soo sorry, unit is DEAD.
