Got some type of starter wire issue!

Had a click no crank situation this morning.

1.Tightened batteries
2.charged batteries using car

No dice. Still click no crank.

Tapped on starter as the key was turned and it fired up. After letting it run I shut off truck, tried crank and was back to click no crank.

Got help again turning the key and as I went to move a wire to get a clear shot to tap it, I got it to turn over. Investigated the wire and sure enough I could move it and not have to tap the starter( saved myself 322.89 ?) . I tightened the nut that this wire is connected to and it did a lot better. Strong crank with immediate start.

Took care of a few other things and cranked it about 15 times and maybe 3 times it would act like it didn't want to start and then start.

What is the purpose of this wire and what else besides it do I need to be checking out?


Sorry for the crap picture. But the wire that my tire thumper is pointing at is the wire

Where are y'all finding 160 starters. I've checked 3 places all want 300+

 

Gonna take those wires off and try cleaning them. I'm determined to not have to put a new starter on.

 

I think I got it. The wire that I push on,directly behind it is another terminal and it was about a nickel thick loose. When I pushed the wire it must have pushed that too causing it to crank. Tightened it down and I'm getting no sparks and it's starting up.


Thankful to have drove home and not be stuck some place.

 

Do you have any diagrams showing where the grounds are
