starter

[no mufflers]

I have read most of the starter related threads but here is my problem. I bought a new not reman starter about a year ago and it is the direct drive style starter and it worked really good for a while but lately it has been turning over really slow. does this sound like a starter problem? should I get the gear reduction starter? the alternator, starter and batteries were all replaced at the same time.

here is how I have my batteries setup.

I'd look at that nasty green neg cable

 

[sjwelds]

Sheesh. Batteries ought not to be the problem.

I'd agree, connection somewhere gotta be iffy.

I looked at that cable and the terminal is clean it's just the wire that looks green. It was all I had at the time. I will look into replacing it and see if it helps. That cable has always been like that that's why I didn't think it would be a problem.

Bruiser's negative cable looks about like that too (worse) and she smokes fender mounted starter relays. Turns very slow. *rumph....rumph....rumph....VROOM!*

I don't either. The clamp is clean and you have got s little corrosion on the wire surface, but the clamp is not corroded. That is where almost all of the problems occur.

I bought a "new" dB electrical starter and it had a dead spot. New doesn't mean good. Do you have an ammeter to test the draw? I second the cable being corroded inside of the lead part.

that's a very bad assumption
if there is any exposed wire, it allows moisture and air access to the wire inside the sheath
it's a safe bet your cable is corroded a good ways into the sheath, and if you check resistance on that cable, I'd bet it's pretty high, considering over 10 feet, 2/0ga cable has less than .001 ohms resistance, the larger the cable and the shorter the run, the less resistance

you should add a second ground strap from the other end batt terminal to the chassis

It maybe corroded on the cable, but that does not restrict the current flow. Surface is where the corrosion is but the wire is solid copper, where the current flows. Use an ohm meter to be sure.

If moisture got in, the corrosion is going to happen where the two dissimilar metals contact, inside of the lead connector. Lead is less noble than copper and is going to corrode in the presence of moisture. I bed it's failed inside of the lead terminal.

 

[crash-harris]

Remember that it's a bunch of little copper strands that make up that cable. The strands must be in contact with each other. If you can see corrosion, you can safely bet that is also corroded down inside the insulation on the surface of every little stand (or will be soon), which creates resistance within the cable between each individual strand.

 

[Shawn MacAnanny]

If he really wanted to test it he can strip that cable back further and bring it up the outside of the battery terminal and vise grip it to the battery post with his ground jumper . Provided there is bare copper under the unstripped cable

Cables are awfully small for one point...flat ground wire should be replaced...all cables should be 3/0 amd direct to lug using military terminals if post type

3 x 650 is less than 2 x 1150 gr 31's

Double ground as mentioned tagged of other end to frame.

Starter could be issue but that green cable is NFG in my opinion.

I am going to replace that cable and terminal and see what happens. the starter is under warrantee and the parts store has the other starter there. if this doesn't change anything then I will be looking at the starter next.
