electronics momentary drop *UPDATE* batteries running at 10.8v

[justinadams]

ok. my problem is that every once in a while all my electronics in my car just drop and come right back. the radio. the lights. but the engine still runs perfect. anyone know why this could happen. this started after i added my second battery, but BEFORE i installed my amp

Check your main conections at tha batteries and at all fuse boxes and your grounds.

Is there any specific time when this happens? Car on? Off? Accelerating?

[justinadams]

no. it's happened only a couple times. once while driving. and once when stopped at a light. and it's only for like a 1/4 of a second.

and i'll check my connections once i get out of classes today.

[huh?do-what?]

are any wires tapped into the fusebox under the dash? Ive seen people try to cram wire in with a fuse instead of using an actual fuse tap. The connectors that touch the fuse ended up bent to far out. Hit a bump and the fuse would wiggle and lose power for a second. Have also seen where a factory power wire from battery chaffed against a battery tray. Put a radio in for customer. He comes back 5 minutes later. Every time he makes a right turn, the radio cut off. It just had to be our radio we sold him. He was certain. then we found the cut in the wire. When he cornered, the wire would touch the tray making the electronics dim for a second. Good luck.

hmm. ok. i'll make sure the check.

could it be cause by my batteries not having enought charge?(i havent checked that yet) or would that just dip and not just give out?

well i check all that and everything was good. and then just for shits and giggles i decides to break out the dmm and test my battery. and first off my car didn't want to start right off. and then it tested at 10.8v. say wwhhaaaattt??? would just chargeing my batteries fix it or do i also need to get a H/O alt? if so...who makes a H/O alt for a 2010 kia forte koup?

Some guys just charge their batts over night once a week or so to keep volts up. But that's killer on your altenator constantly charging full tilt. I'd say get a hold of iraggi and maybe see what they can do for you or kyle at dc might have a solution
