What are signs that my power supply isn’t providing sufficient amperage?
A bottom keeper failing to release may be caused by inadequate amperage at the strike. Voltage may be in the correct range, but without proper amperage the bottom keeper may not release, or there may be intermittent operation of the 9600 keeper. Verify operation with a good battery or different power supply. It may be necessary to upgrade wire size, or switch to a power supply with more amperage.
