i have a stinger SPC122 and the blue accent leds turn on for 5 seconds and then shut off. is this suppose to happen? and also when i have my key out the thing is still on...?
You don't need to worry about a voltage display on the cap. It's really nothing. If you're that worried, get a DMM and measure the voltage when the display goes off. Depending on how your power is connected, even when you cut the engine, there's still power being supplied to the amp/cap. The only reason why the amp turns off is cause of the remote wire.
