Please help - alternator problems

[Savackz]

So I was driving around and my alternator was charging around 14.1 for about 30 minutes and I thought it was just a weird day. I turned the car on a couple hours later and it was at 12.6v. Didn't go up or down at all. I was reversing out of a parking spot and it suddenly jumped to 14.8v. And now went back down to 14.1. What is happening? It's an excessive 250.

Sounds like you have low rpm and it's turning on once you get to a high enough rpm? Did u get a hairpin?

Could be a loose pulley (hopefully)

Don't overlook the simple things, the front battery fuse holder burnt up from a loose connection so it was just not reaching voltage from front to back.

Yeah, might be an excuse to order some ofc wiring and make sure I have good connections.

OFC's the only way to go, imo.

Welding cable is cheap, so there's no reason not to use it

Only reason I am using cca is because I got all of my wiring for free so I might either buy it much later on during the summer.

Someone wants to trade my dsp and the rcas and the program I have for it for 100 bucks and a set of battery terminals which I am going to end up doing.

Is there a point to getting 2/0 welding? Or should I just go with 1/0? I've heard that 2/0 is more like car audio 1/0.

Dont compare welding to car audio wire.

If you are pushing 500+ amps then a single 2/0 welding would be good.

If its 300 or less then 1/0 will be fine.

AWG standard beats all CA rated wire no matter what.

It's just my single sq3500 at 1 ohm.

I ran my sq4500 @ .5 ohm on a single 1/0 welding wire.

I fused at 350amp

But i had a secondary battery 1 foot away from the amp.

So 1/0 should be fine or just pay the extra 40 cents per foot for 2/0?
