Replaced battery and alternator after the truck died after a 5 hour drive a month back. i had to replace the battery and alternator since the truck was holding 10.5 volts on the old batt/alt and i was 5 hours away working in another town so i had no choice to replace both to make the 5 hour drive home. now the truck does this weird thing were it will only start charging once you hit a certain rpm range. ive cleaned the grounds under the driver side on the frame rail. The one under the rad support to battery . Replaced the broken hood to body ground. Checked the body to block ground strap and now the truck will ONLY start charging once the RPMS hit 4-7k and then the truck runs completely like normal and holds voltage at any rpm. untill the truck is turned off and you have to repeat the process of having to rev/drive the truck up to 4-7k rpms and voltage jumps to 10v to 14.5v. i don't mind doing this when its warm lol since its a quick fix but its not ideal and the problem is winter is coming and regular -20c to -30c temps soon so i don't want to be hitting those rpms to keep the battery alive when the truck is still warming up. ive read that 2005 models have some kind of module on the ground. just wondering if anyone has experienced this weird symptom .any ideas would be helpful, thanks guys. 2005 gmc sierra 1500 4x4 -
Ok, so after many weeks trying to fix this.. I have a 2013 Silverado LT 4x4 extended cab 4.8L. A couple months ago I was driving thru deep snow and my parking lights went out. (not sure if that was a coincidence or not) Anyway.. I checked the 3 fuses under the hood, all had no power) I switched the relay for the parking lights, didn't fix. I looked at fuses, none were blown. I replaced the distribution block where tail lights plug in with lic plate lights and trailer lights. (was a little corroded, didn't fix the problem) If I run a power wire into the feed side of the fuse block under the hood ( half fuse goes into the power side other half goes to the lights. ) the parking lights work... By the way all the other lights work (headlights, turn signals, brake lights) I tried looking for maybe a faulty ground but wasn't sure where one would be that connects just the park lights. Please help. Im at my wits end... Any help would be great
