What gauge of wire are you using with your relocation?

Just curious, as I'm working on a dart with a pretty stout 440.

It has 2gauge, and I think it needs more. I'm want to move up to 0 gauge.

Thanks in advance.

imho if it's a quality wire (i only use welding cable) id leave the 2ga in there. if it's properly installed it should be fine.

With a new powermaster starter, the ignition disconnected, and two red top optima batteries, it doesn't want to turn over hot.

We've replaced the starter 3 times, and just upgraded the cutoff switch to a 300 amp unit.

I recommended heavier wire to the owner of the car prior to the last starter change, but he wanted to try this first.

The 2AWG wire that is in the car now, came with the Taylor wire products relocation kit.
I know they sell the kit with 1awg too, so I was curious what other guys were using.

We're running out of things to rule out.

Make sure the ground is good... and as large as the
hot positive lead

I use 2/0 for starter power and body grounds.

Interesting. Shows 0 or 00 depending on the draw, on that chart.

I suggested 0 to the owner, prior to seeing that chart.

Thanks for the link.

And yes Mr. P body. I agree, that the ground needs to be as big. There are several heavy grounds on this rig. We started there.

Got to figure both ways, so the it's like 20' or 240".

I go to the welding supply and get the biggest cable they have. That is one area I want absolutely no trouble from. Welding cable will have far less voltage drop than a battery cable will and is also more flexable for routing.

I ran the BIG welding cable for years but when I re did my interior, I had Napa make me a #2 iirc which was way smaller AND lighter and it works great. Like Mike said, the grounds are very if not MORE important the the lead wire.

Most hot rodders that do not have a education in electrical theory don't know that all the battery current travels from the battery(all battery are the same)negative post through the sytem and returns to the battery through the positive post Hence the importance of the negative leads

Hence the EQUAL importance of the negative leads

Update

0 gauge both ways. Turns over like it doesn't even have plugs in it.

Thanks.
