agree. But in his case he has crappy connections and unknown condition of the cabling. You could try it with existing cabling, but if it doesn’t work, I would suggest removing existing cable, run a known good jumper cable to supply power to starter (connected to known hood fully charged battey), then jump connection as described.

to say another way, if you use existing cable and it doesn’t work; you still have possibility of it failing due to the cabling (and not because of batt or starter).

 

True. I was just suggesting to start with the simplest thing to try. If that works then yay.
If it doesn't work then you are correct it could be crappy connections/wires or crappy starter.

 

So when I change those wires and then the key the noise goes away but when I turn it back and take it out the noise persists?

 

Should the emergency brake be applied before jumping it with a screw driver and you say the positive patter post. Can you circle the two thst I’m suppose to jump?

 

did you watch video you posted in 264?

the e brake has no bearing whether starter will work or not when doing this test.

 

I meant as a safety precaution,

 

The noise in your video sounds like it's coming from the back wall of the truck cab? That's the BCM and the only time my trucks have made a weird noise back there was when the battery was dead. So I'm inclined to think the problem is a crappy connection or crusty wire still.

Park brake would be a good idea only so you don't run yourself over if the vehicle were to roll for some reason.

 

or run a separate cable for the solenoid and give that 12v power when you aren’t under the truck

 

yeah i tested the battery after that and it had drained half way and was like 5-6 volts. About to try and do one of these suggestions soon as I get a chance because I don’t have much time left before I have to move it or have it towed somewhere

 

Do you think it could have anything to do with the new alternator I put on?
