I have a Lighting audio Strike 1.0 fared cap with the digital monitor. It was running steady @14.4v sometimes even 14.7, I took the car into the shop to have some foglights intstalled, (they didnt even finish). (i left the fuse in my power wire, so the cap was hooked up, but not on, maybe they drained the power from the cap, or maybe the foglight installed ****ed something up?) now my cap stays @ 14.0v and sometimes when my car is in park its @ 14.2, and sometimes when i first start the car up in the morning its at 14.7 now, then it will drop (i have a deep cycle fosgate battery). Do i need to charge the cap? if so, how exactly do i do it? will a christmas light work? and do i need my car turned on, because my cap has a remote hooked up to it so that it only is on when the cd player is. also a long time ago my cap used to run at 14.0v a while ago, until i grounded it better and gold top terminals for my battery. when i drive my car now, it will sometimes go up to like 14.1 or 14.2 but then drop back down to 14 or 13.8 when im stopped at a light, and i wont even be playing my system loud at all.
