Should I Upgrade Ground Cable?

[Homeless Man]

I was talking to someone on here about slow starts because of starter heat-soak on a warm engine and one of the tips he told me is to change the ground cable in the trunk to a thicker one. What exactly does this do and should I do it? Also can someone send me a link to what I should get?

My SS turns over slow all the time. I plan on replacing the battery with a better one

Battery is new

Mine has turned over slow since day 1. I guess I've never heard anyone else's SS start, so I have nothing to compare it to, other than other vehicles I've owned in the past.
I assumed it was normal.

Sounds like your car only turns over slow once the starter has been subjected to "heat-soak", I don't think a bigger NEG battery cable will solve your issues. While it certainly won't hurt anything to put a bigger NEG cable on, you would need to increase the size of the POS cable as well.

The increase in cable size allows for a greater current carrying capacity. When the starter motor heats up, the copper windings that make up the motor and field circuits increase in resistance, meaning you would need to supply more current to the starter to get the same performance when the starter is cold.

It's not the cheapest option, but a high torque mini-starter, such as the PowerMaster XS Torque series will solve all of your heat soak issues.

If the issue is just a weakening battery, nothing will fix that other than a replacement battery. Good luck!

Have you checked the terminals at the starter?

Still chasin this one huh? Just askin did you chase down and clean every ground connection..in the car? Heat soak on a ground cable..in the trunk? Only reason would be if that cable was damaged/kinked some how..did that happen?

Lol..still no sig with your specs..It would make things easier when peeps respond with legit suggestions...just sayin...

FYI...when I upgraded my stock ignition wiring with a MSD harness upgrade, I tapped off the hot on the engine compartment..and that connection was also a bit corroded which I cleaned off...so you may want to check that also..good luck...peace out..

Not really chasin it because I know what the problem is. I changed the starter myself at the beginning of this year and that solved everything perfectly fine for a few weeks but now the problem has come back. Funny how I made a thread before I changed the starter asking if I should get one of those high torque ones and everyone told me no need to spend a lot of money and OEM is better even though aftermarket doesn't cost that much more.

After my car was tuned it stopped turning over slow. Might have something to do with timing while starting. Not sure. I also have a good AGM battery

Do you have header pipe mod that runs near the starter?

I did the same thing (replaced the starter), had the same problem (worked for a few weeks, back to hard starts), and I'll bet the terminals AT THE STARTER aren't clean, offering a bad connection. The problem is, when the starter gets hot it pulls more power from the battery to work. If the connection AT THE STARTER isn't clean, the starter does not get all of the juice and boom: hard start problems. Clean the power wire connection AT THE STARTER, apply some dielectric grease and you should have better starts.

Also, check your grounds from engine to chassis. I found one that wasn't on the block and it also helped with my starting problems. It was even starting to weld itself to the bolt holding it. Clean them up and apply a bit of dielectric grease.

If you go with the high torque starter I hope you check/clean the connections because those aren't cheap. Good Luck.

Edit: Check this out. Someone else found a bad ground on their engine and starting has been perfect ever since:

What are u talking about I always listen to people's advice on the forum and private message with many people. Don't have anything useful to say don't bother posting on my stuff

Mine turns over slow all the time. It has nothing to do with the temperature of the engine.
