Question about STARTING and Voltage Issue.

[MATTHEW J PALUMBO]

when you get this low voltage thing going on where are you checking the voltage? try checking at the alternator output and then check it again at the battery.

The voltage is checked at the alternator and battery.

We recommend that you put all your rig(s) info in your signature so we all don’t have to guess at year, make, model, engine size, trans, rear axle locker…….etc. While you may have posted pertinent info in your first post, you may forget to do it again and the info is needed by us anyway. Makes it way easier on all members that attempt to help, to have that info right up front. It is also recommended that you take a pic of your RPO codes, on the inside cover of the glove box, and post that image in your signature. All this info will greatly help those that will try to help with a problem.


If there is any other info, like upgrades, mods or recent mechanical/maintenance work done, that would be helpful in any post as well. Too many times a question is asked by the poster and after about 10 responses we find out that the poster has done recent work to attempt to fix the problem or work that was done that SEEMS not related to the problem.

What occurred is what was detailed in the post. That is the chain of events. NO WORK done prior to the issue. It was good to go the day before it went in for state inspection, left the dealership drove the 1 mile to my house and parked. The next day is when the issue started. Coincidence.

Great Article. That was my next approach. Ordered new cables and cleaning all the connection points.

Welcome to the Forum from NH.

You've already received lots of great suggestions from knowledgeable folks here for items to check out. These truck are notorious for electrical issues, when grounds become corroded and are not clean and tight. Generally, the first item that we check are all grounds in the engine compartment, to ensure that they are clean and tight.

Continue to report back on the suggestions above, we we will work with you, until your issue is resolved.

Will do. Waiting til the end of the workday and will be out underneath verifying, cleaning and replacing as needed.

OK. Removed ground. Cleaned all contact points and connectors. Reassembled and happy to report success. I dont have the new cable to replace with yet, waiting for delivery. Also noticed another improvement, no fluctuation in the blower fan while the AC is running and I am coming to a stop.

Thanks for the great info and appreciate the assist!

Vehicles in rust belt areas have this problem more than the rest of us. Glad it is now fixed.
