I bought the first generation right angle grinder from a guy in “new” condition. When I put a battery in and press the trigger it runs. But if I stop and let it sit, the white light under the trigger never turns off. If I don’t immediately pull on the trigger after stopping, it will stop running until I pull the battery out and put it back in. White light never turns off while battery is in. Any help is welcome
