Severe Voltage Drop

[Marc5458]

I am having a issue with a voltage drop capacitor starts off at 14.1 and drops as low as 9 1200.1 kicker CXA It was working fine bought a AGM battery I have 0 gauge wiring all of a sudden I'm having voltage issues

You shouldn't have that much voltage drop with that amount of power. Sounds like the voltmeter is connected to the capacitor, is that correct? I would check connections if the new battery is the only thing you changed before the problem started.

What kind of cap is it?

And what is the resting voltage on the battery (motor turned off and car has set for a while)?

Found that my power wire at my fuse block near my battery was almost burnt into. It was only a small thread still connected leading to the amp. Now I have to figure out what caused that to happen.

12.2 resting

Probably a loose connection or inadequate wire gauge.

Throw that in the trash.

That's a little low. The capacitor is just a weight on your system IMO, isn't help.

That battery voltage says to me you'll need a new battery soon. This is a good chance to invest in a good battery to help give your system more juice. Can you charge your battery at home with a slow deep charge?

Because either your battery is old or you need to charge it. Having a voltage of 9, I've only seen that with batteries had a bad cell in them. I've never seen a battery go down to 9 volts that wasn't bad. Idk if that's battery voltage, I wonder if that cap is just like a short circuit after you drain it initially.

Thanks I bought a AGM battery but I found that is was a wiring problem my power with was burned almot in to at the battery fuse block causing the low current to the trunk
