02 Durango wont start/electrical problem Sign In

02 Durango, 4.7L

Was fine Monday when my wife was running errands.
Yesterday, when you open the door, interior lights come on, everything seems normal when key is switched to on, but as soon as you turn the ignition to start, everything goes -completely- dead. All interior lights and the instrument panel go completely dark. Let the key go back to on, and the dome light and instrument panel will slowly(almost like everything is on a dimmer switch) start to come back to life. Try to start again, and instantly back to completely dead - even stepping on the brake at this point will kill everything.

Thought it might have been the battery, which was still under warranty so I took it in, and they tested it. Measured 736 cc amps, so figured it was OK - swapped the battery from my other car in just to make sure, and same result.

Positive battery terminal corroded through earlier in the summer, at which time I replaced that side. Figured it wouldn't hurt anything, so I replaced the negative side yesterday, too, but no joy.

Tried moving shifter around with some enthusiasm to see if it could be a neutral lockout switch issue, and tried starting in neutral, but all with no luck

At this point, it almost seems like a ground problem? If so, is there a good place to check first, or what would my best bet be?

Thanks so much for any help!!!

Did you replace the battery terminal end or the entire cable?

Just the ends

Check the entire cable for corrosion. Sounds like a battery issue but if the battery checks out then possible cable problem. A lot of times when the end is bad it is only a matter of time till the cable gets there too. Good luck

I agree with Jeff. It's definitely a voltage loss but the question is where is it happening. I would say it has to be a cable connection somewhere. Follow all the cables including the ones to the power distribution box. Try tugging on them one at a time while someone else is holding the key in "start" position.

To add: Just the ends at battery are usually the real cheap ones. If those didn't cost 12-15 bucks each they are really of marginal help and usually marked "temporary" on the packaging. IMO - whole high end cables is the way to go and would bet that's the problem as I think Jeff does too,
