It sounds like your talking about the big cable? I need the readings off of both cables please. 400mv is nowhere near enough signal to start it. If that's the big cable with that reading then replacing the cable will fix this. If its the little one then there is something wrong on the ignition side of things. 1000mv equals 1v by the way so u should have 12k if reading mv. 400mv could just be voltage noise. Or a bad ground. U hooked the ground up on the block right?

could be a bad battery..
battery with enough volts will turn on the components in the car but if it doesnt have over 450 amps it wont start the car..
(450 amps could be wrong, when i tested mine it read 212 amps and it was nowhere near good, soo maybe anything higher then 300?)

idk like i said just have pep boys test it.. if its bad then its the battery,
get a new one and if it still doesnt start the car its the big wire going to the starter.. replace that and should be running!

Ok, so I pulled the big wire off the starter and a plastic ring (seemed to be used so the nut doesnt touch the starter) broke in half and cant use it. is it needed or no? wanted to make sure before hooking the battery cable up.

The wire thats grounded to the block, it grounds to one of the two bolts to the left of the diamond like plate right? or does it grounded to the nut on the diamond like plate?

We need to figure out if he is getting voltage before we try checking for amps.... mv is a way of checking for small voltage. And he said in the OP that he put a new battery in it.

And Congo u still haven answered three very important questions for any one tohelp u trobleshoot this problem. Let's focus on one problem at a time so we stay on track with the title of the post. The three questions are .....

the voltage reading on big cable.


Voltage on small wire goin to starter when key is being turned..

And is the main ground cable hooked up to the block.

I know u gave me A reading but didn't specify if it was the big or small wire.
