A lizard crawled into my old charger next to a window in the shop and shorted out the circuit board. Be careful where you put the charger and put fiberglass screen around vent to keep the small critters out. The board doesn't tolerate them.
I have an older drill. when the charger is plugged in i get no light at all. When 18v Nicad 2.4 ah battery placed on it ,Still nothing. Is it worth replacing the charger? Both batteries are dead. No way of telling if they are still good. Would hate to buy the charger and have the batteries not work (no replacements for them. Can i return charger if Batteries are the issue?
