Battery wiring and grounding questions

[Ford_Falcon]

Hi viewers,

I've got a '94 Geo Prizm 1.6 MT and have noticed the engine won't start from time to time, but adjusting the battery wiring and it gets power. Looking at the battery cables, they've seen better days. So I decided to replace them. This leads in to my 2 questions:

1. On the negative (-ve) terminal, the cable on my car has two grounding wires that hang off the cable. One ground wire runs from the -ve post to the body. There is a second grounding wire (two parts) at the other end of the main cable. It too connects to a different point on the body. The two parts are joined by a connector with a plastic shroud. The main cable runs from the -ve battery post and attaches to the metal support bracket for the right side (driver side) engine mount. Is this correct?

2. I replaced the -ve post cable with a new length of 4 gauge wire. What do I need to do to replace the positive (+ve) cable, as I see it runs into the main harness?

Thanks

Dave

Welcome to the forums! The positive battery cable runs to the starter motor

Thanks KC. So I would need to open the harness, remove the existing cable, and attach the new one, connect it to the starter motor, then shrink wrap the wires again. That's what most would do?

Yep, you got it . Just be sure to remove the negative battery cable first

Because of the age of our cars I DONT recommend opening up the harness. The wires and connections get brittle and break when disturbed. Instead just zip tie the new cable alongside where it needs to go and snip the old ends.

Just trying to save you from another headache.
