Hi everyone, here's a stumper. I have a 2001 Chevy Silverado with a slight electrical problem. The battery light in the message center flickers on from time to time and sometimes stays on for about 30 seconds and goes out when ever the engine is running. I do think it's weather related. As soon as the temp seems to drop below 50 outside the problem seems to minimize and even go away for quite awhile. THE VOLTAGE is good. 14volts plus all the time. The volt gauge don't even flicker when the battery light comes on. I've checked with a volt meter and all the grounds for the engine are good. I know some friends that have 2003 and new chevys that have a dash cluster problem. They say the solder on the connector pins can be bad. Can anyone help. Low mileage truck that I bought new. I don't want to take to the dealer locally. They'll spend at least $300 or more of my money. The alternator charges fine and isn't grounding out that I know of. Thanks... Lots of luck with this one..

I have the same problem with the battery light flickering. I have a 2002 Sliverado. The problem started about 4 years ago. It will not happen for weeks then it will start again. The dealer could not find a problem but charged me $90. Recently the battery died, it had a cracked case. That seemed like an unusual way to fail so I suspected overcharging. I have a voltmeter connected to the battery and alternator which I can monitor while driving but have found nothing unusual. A couple of years ago I had the instrument panel out and measured signals there but did not know enough about how the message center is controlled to find the problem. I'm currently trying to figure out how the message center gets it's signals so I can monitor them to see if there is a correlation between the light coming on and any of the signals. This is not easy.

 

Any tips would be appreciated.

Hello,

 

Same problem here. I have been seeing this for a few years. It happens for a week or two then works fine for 6 months or more. When the battery light flinkers it shows no pattern. Replaced battery, chased the positive and grounds, checked connections and checked for codes........nothing to date has helped.

 

Looking forward to any feedback or thoughts.......

Thanks,

Terry

Wondering if anyone has come across a fix for this. From the list of people that responded initially, it looks like it's limited to 01 or 02 trucks.

My light still flickers intermittently with no ill effects. Just kind of annoying.

Might be a stupid suggestion, but have you checked the negative connection on the battery? I had an H3 and the lights started flickering on the expressway as I hit bumps...ended up being a loose negative connection on the battery.

      2 speed transfer case optional now?

      By newdude · Posted

      This is a 1/2 ton thing ONLY.  All HDs 2020-2026 have the two speed transfer case, with Autotrac as an option.     1/2 tons 2019-2026, regular 4x4s come with a single speed case (no 4LO!), and trucks with Z71 ordered, or all Trail Boss trucks come with the 2 speed case.  2 speed case is also an option on WT, and is also standard on High Country.

      Different requirements for oil filters?

      By newdude · Posted

      2013 5.3 still to this day calls for the PF48 filter.  Which as a 15psi bypass pressure.     There is a TSB, 17-NA-157 that talks about the PF-63 and PF-64 filters which have a higher bypass rating of 22psi.    TSB HERE - temp.xml   "Beginning in 2012, the oil pumps began to regulate main gallery feedback instead of pump out pressure. This means that the oil pump now does not begin to regulate until pressure is built up to the main gallery. This change reduces the amount of time it takes to provide oil to the engine bearing and lifters during extreme cold start conditions.  Main gallery feedback oil pump control systems are present on the following engine families which use Spin-on oil filters: Small Gas Engine (SGE), Large Gas Engine (LGE), High Feature (HFV6) Gen2 and Small Block Gen5 gasoline engines. These engines with the main gallery feedback oil pump control systems are factory built with an ACDelco® oil filters"   It also calls out what engines use those filters.  The gen 4 small blocks were not on that list (LMG, LC9, L9H, L92, L94, L20, L96).  Gen 5 small blocks use the higher pressure filter.          That all said...   Your 7045 Napa filter is the PF63 equivalent, with 22psi bypass.  You are already using the higher bypass pressure filter.  You CAN keep using it, you don't technically have to use it though.

      Do you know WHY the filter relief setting was increased to 22 psig?    When the new system goes into the second stage the pump volume ramps up considerably. It was found that the 15 psi filter bypass setting put the filter in bypass on a warm engine when the second stage was activated. Raising the filter bypass setting forced the filter to do what it designed to do. Filter. Preventing debris from circulating during high load, high rpm operation.    So next question is how did GM find this out? VLOM/lifter failures and a deep dive by Melling Corp.    Last question. Is it required? Look at it like this; a motor may be equipped with a rev limiter. But it only works if the set point in reached. That 22 psig setting only matters if the pressure differential across the filter media exceeds 15 psig during normal warm operation. Second stage kicks in around 3000-3500 rpm.    I can't answer your question because I don't know you and how you use the truck. But I think there is enough information here to let you decide for yourself. 😉

      2020 Trailboss 6.2 replacement

      By newdude · Posted

      Probably not their first rodeo, so it should go as planned most likely.  Typically the service manager or tech doing the swap will put some seat time to shake it down after they get it all put back together.  We usually put 50-100mi before we hand them back so if something happens, its not after you get it.  A coolant leaks, oil leaks, a ground left off or loose, vibration, etc.     The new engines so far have been good?  There's been a couple that have popped out there again (the replacement engine) but most have been okay.
