Grounding Points

[calinaki]

So I'm starting to see some weird things going on electrically in the ol' 95 4 runner. I wanna clean up all the grounding points,... so Battery, Battery-to-inner fender, and I know there's another spot at the back of the engine,.... where else should I be looking for important grounding spots? Does the Alternator have a grounding cable or is it just grounded by it's mounting points?

Thanks in advance all!!!

You can reground the alternator

Use 4 Gage ground cable

It's always a good idea to keep your grounds in good condition. Google "big three 3.0". Lots and lots of writeups on this one.

There are 3 ground wires; battery to fender, firewall to engine, and underneath there is body to frame. You can add additional or heavier wires to improve, just make sure all ground connections are clean and tight.

I see the battery to body on the inside wheel well--which is the easy one. Does anyone know where the engine ground is and the best way to access/check it? Also, I don't know where to start looking to find the frame to body ground connection.

Sorry I'm so ignorant! thanks for the help!

what engine do you have

If its 3.0 there is one on drivers side right under intake tubing.

There is one that attaches to the block right behind the alternator (that same harness connects to the alternator). It also connects to the driver's side wheel well. The other is down by the AC.
