Hey there, I got an HPI pro rechargeable glow plug igniter....how the heck this thing works??? I charged the igniter for over 12 hours using the wall charger that came with it, but the freaking needle in the charger still is in the red zone...didn't move at all...so what's wrong? is that needle supposed to move when it is charged or is it an indication of a charge of the plug? i mean when i put the igniter over the plug then will the needle move? is my charger broken? how far do I have to attach the charger to the rechargeable igniter ( I made sure that the nut from the charger was completely covered inside the igniter), so what is wrong here?
