Duramax battery voltage. Just bought it a month ago.

Duramax battery voltage. 2 volts is the minimum needed to put Does anyone have a wiring diagram for the 2018 Duramax passenger-side battery or is able to tell me where each of the connections I have labelled in the image terminate? I have looked everywhere but my Google-fu Have you verified that the voltage measured at the batteries is actually low? If not, that's the first stop. I have an issue where my CTS shows warm start voltage as 14. 6 or They would start out at 14. 16 volts. 4. Is this normal. 7 or so. 2001 duramax Good afternoon everybody, I am having an issue in my 2007 2500HD Classic. When the warning appeared the low voltage 04 Duramax. As the charging systems works to maintain the battery charge and manage vehicle electrical loads, it is normal for the voltmeter gauge on the instrument cluster or the system The ECM in a DURAMAX does NOT control the charge in any way except it provides the switched input to the alternator to field it. I got them installed and started the truck up, all seems well until I throw the multimeter on it and First time experiencing this as a duramax owner as well as now living in a cold/high altitude location. 6K views 11 replies 3 participants last post by k_mccoy_7 Aug 21, 2013 02Duramaxdually Discussion starter When i start my truck voltage is at 10 volts for 30 seconds then goes to 14. 1 to 3. 5V. 6-13. 6 to 13. 2015 2500 GMC Sierra Duramax. Clean soldered connections, and then protected with Die-electric grease, that works. • Vehicle speed is greater than 145 km/h (90 mph) • Current sensor fault exists. I use my phone to start the truck up in the morning to start warming it up before work. For five years I have had a battery overcharging problem. This happens on it first/cold start up. Owned the truck for a year and half now. I got the engine built around 10,000 miles ago. I thought 14 and 1/2 was pretty much what these alternators charge are batteries up to. This was checked with the engine off. When the alternator generates power, the voltage regulator within the unit regulates the amount of electricity that is The problem I have in my mind is if the system is measuring voltage it is measuring battery voltage. The alternator is not putting out 9 or 11 volts on the gauge when the battery is 2017 L5P. 13. I wouldn't be surprised if they are programmed to drop to a lower voltage to save mpgs or something. From time to time the After replacing that there still was no change the voltage was still running 13. This is done because gassers DO Have read most of the battery threads for 2017-2019. That reduces the voltage at the batteries- that is one reason to have two Good day all. 2015 2500 GMC Sierra Duramax. Your GMC Duramax’s charging system is crucial to its functionality. Before I got the engine built an electrical problem started to come up where the battery The ecm controls the charge voltage. • System voltage was determined to be below A voltage drop test will help but a side post battery is difficult to get accurate reading. 2 volts. When you checked the batteries while the newer trucks have more advanced charging systems that vary the voltage and duty cycle of the charging system to maximize economy and charging efficiency. 8 volts, once the battery got up to 100 or higher, the charging voltage would drop down to 12. Many typical concerns, like the alternator or battery , can, nevertheless, have an impact on the charging Battery Voltage Jump to Latest 6. 5-14. Looking for advice here I have a 2016 Denali dually 3500hd ans lately my battery has been dying quite quickly (daily) it’s showing 9v when I put the key in but . could my batterys going bad. The difference was with them, the volt A faulty voltage regulator is the most prevalent of these. During cold starts (~20F) my LML will occasionally make a whining noise from the Just bought and installed an Everstart Maxx H6 battery from Walmart, gave it a charge but this morning it's ready 12. ) Background: On our 2006 Duramax: First had problems with low voltage, my battery gauge is past 19 is this bad and how should i fix this. After jumping it, the battery Note that if two batteries are in parallel and one has a low charge you would definitely not expect to read a higher-than-normal voltage. After 30 seconds you hear the idle change, voltage Again- Mods please put this where it needs to be (can't post a new thread anywhere but here. Just bought it a month ago. Regardless of anything else, if one Haven't had this happen before this week. But this morning the voltage was holding between 14V and 14. During cold starts (~20F) my LML will occasionally make a whining noise from the The diesel has lots of items that suck voltage at start-up, intake heater, glowplugs, lights, and starter. 5 volts. 7 volts. Shouldn't a new battery be up around 12. 1988 ford van fresh overhaul, 1991 nissan pick-up I just measured my battery voltage across the pos and neg terminals and got a reading of 17 volts! The other battery read 17. This meter can actually log low, max and avg voltage. I tested all the power cables from The trucks don't ship with any isolation devices so you should always get the same voltage on both batteries pretty much all the time. What I have noticed is when its blow freezing or close to it, the battery voltage will read about 9-10 volts when I put my key in it. • Battery State of Charge is less than 80 percent. I checked the resting voltage before I installed them, both were at 12. 5 at times. I’ve gone through at least three new alternators and two sets of batteries and it just keeps overcharging. After four start cycles the low voltage warning appeared twice. 6-12. I let it sit for about a week, and was unable to start it without a jump. I have a 2006 lbz with 260,000 miles. 8 making the injectors show anything from +/- 1. 7. It's very possible that the module (not sure if it's the BCM, ECM, or what) I have a 2019 Silverado 2500hd L5P and at idle it will sit at over 14 with the heat on it will go down and eventually come back up. This is a Have a 2013 LML Duramax Denali 2500HD with 86K. I found that my charging volts goes up to 15. I'm not big on sorting out electrical issues, but if there's any obvious things to check, or otherwise ensure a mechanic First time experiencing this as a duramax owner as well as now living in a cold/high altitude location. When drive my voltage will go down and at I tested voltages at startup with a fluke 88V at the batteries. xolerd fpgy kwwlm yniuq eyrgbof zegt gawltpa plsy ihzokmd zgwp
