correct wire gauge from battery to the starter

correct wire gauge from battery to the starter

Postby misterjones [OP] » December 6th 2019, 8:52pm

I was replacing the starter on my 2000 Safari when the eyelet on the cable running to the battery broke off (the heavier gauge cable). I'm assuming this is 2 gauge wire, but is it? I'm having a bear of a time finding 2ga long enough to get from the battery to the starter locally (last one was 42"), but 4ga long enough is readily available. Can I go with 4ga or do I really need to stick with 2?

bigger is better. Clamp/solder your own ends on and get the wire from an electrical supply.

crimping 2ga wire without the proper tool is near impossible.

I always went 1/0.. but that was with battery mounted in rear
I would definitely not go smaller than 2awg.
If you shop, you can find it. Welders use it too.
They might even carry it at Home Depot.
You could order a piece online.
Trucking supply, boat supply, alternator rebuilders, etc, etc
Heck, some LAPS carry heavy gauge wire with ends already on.

The hammer crimpers can be had for about $15 so that is not really a deterrent. Or go to a local hose/cable service place and have them make the cable for you.

One additional question: The heavy gauge wire coming from the battery, does it go directly to the starter solenoid or does it terminate somewhere else and the solenoid gets power from that termination point? I ask because I'm looking at this diagram and trying to make sure I get this right.

Ok.

So, I installed the starter completely using a 78" Duralast 4ga battery cable. The old wire is still there and the new one is running alongside the protective covering because I simply didn't really have the right equipment to do this in the first place so when I have the money to get a pair of heavy duty jack stands and a proper 6 or 12 ton floor jack so I can really get it up in the air, but all I had to work with was a small 2 ton jack that I bought years ago for my old Escort.

So far so good, the starter works well and all things electrical seem fine.

Thanks for the help.
