Brand new charger from Christmas. Finally took it out of the box to top off a battery in the garage. Hooked up the clamps. Connect the cables together. Plug into wall. Saw it had a reverse polarity light on. Looked at the clamps and smack myself on the head.
Unplug from wall.
Swap clamps.
Plug back in.
I hold down the mode button for like 3 seconds and see it allows me to change to AGM
Charger light starts up at 25%, then all the lights faded off.
Looks like it's dead but left it plugged in for a few more minutes just in case.
Yep, looks dead. Tested the outlet to make sure it does have power.
Held the mode button down for 1, 5 and 10 seconds to see it there's an off switch or sonething.
Something I'm missing or it sounds like this charger is dead?
