Service Battery Charge System

Battery acted as if dead checked battery good still slow starts as if battery low checked alternator it checks to be good voltage Guage on dash fluctuations between around 10 and around 16 volts this just started

I have had an issue with the battery being dead everything I tu re n it off for awhile. So I did a draw test and found the #20 fuse is causing a draw. What all does this fuse operate and how do I fix this

Drains battery after 3 days

Drain battery in 8hrs when is park overnight

Headlights flash after changing battery

It has been running well. Started up fine this morning. Got to my appointment. Came back out to leave and truck would not turn on. It was as if the battery was dead. When the AAA mechanic checked the battery it was fine. But the dash lights would not come no when the key was turned. Then they did but there was no effert to start. The engine might click but nothing else. The dome lights were bright and working. It was putting out a full voltage the mechanic said. But again the dash lights would not come on. But then they did again.

New battery, new alternator , if my truck sits for more than a day it's dead, looking for I drain I noticed my shift indicator light stays on after the truck is off and keys are out the Lil orange light doesn't turn off? Possible drain??

After charging or jump starting the truck it will run. But after sitting the battery drains out again. The Stanley battery box shows the alternator is good. I tapped the starter,checked ground to the starter and block. I also checked fuses and the starter fuse does click and traded it out but still no start.

It won't start. It turns over and acts like it's going to start but don't. I thought it was a problem with the security system but I've done all the bypass tricks that normally work but it won't work. I've changed all the spark plugs and fuses and the battery. Also changed the fuel pump. I've checked all fluids plus the fuel pump and starter and both kick on just fine. The security light stays on flashing and the battery dies extremely fast. Anyone know what the issue could be and what I can do to fix it? My truck is the newer body.

Old battery went completely dead, changed it and now I don't have any turn signal noise, door chime, and my radio isn't turning on. I checked every fuse possible and still nothing, any idea what could be the problem?

Got home turned off went to start in morning and wouldn't crank no start the dash lights up they said battery was bad so went and got it replaced but still no crank no start

Stalls out while driving at low rpm , changed alternator, battery and 2brand new fuel pumps and still stalls , getting worse, before temp gets up it seems to run A ok ???? Please help !!

Put a new ignition switch,no security displays battery,starts for 3 secs. Then dies

I have a 2004 chevy silverado1500 5.3 will not turn over. When I turn key on it. Has power to every thing good fuel pressure,battery full charger good power connection everywhere but will not turn over I've jumped a wire from the starter solenoid to the hot post on the battery and it will turn over but still won't crank but when it warms back up above 30° it will start just fine i can't figure it out I drive it every day back and forth to work it really frustrating because it make me later for work during the winter

I was pulling trailer and my brake system light came on then it died. It will not start doesn't even try to start. Brake system light is on security light and battery light is on. With key off all my gages and running lights stay on

I noticed my headlights on a few hours after I got home. Thankfully my battery was not dead yet, but I can't get them to turn off! My husband pulled the fuses and relays (I think that's what he said they were). They still stayed on!! He finally disconnected the battery. Please help!!

Parasitic drain on battery on dash board cluster and radio

I hope someone can shed some light on my issue. When using the turn signal to turn left, it blinks once normally on the dashboard then blinks on and off rapidly. The tail lights are not lighting up or blinking to indicate that the turn signal is on. I also noticed that the hazard lights also do not flash in the driver side tail light. I checked the fuse box inside next to the steering wheel and noticed the BCM fuse keeps blowing out. I've replaced it multiple times but at this point I'm just wasting fuses. I just got a new battery and ordered a tail light pigtail because it seems like someone'… Read complete

I get air on both sides but the air from the driver side vents is only slightly cool. I did a hard reboot of the electrical system by disconnecting the battery for at least 15 minutes than reconnecting everything. Didn’t fix it. 2022 Silverado 2.7 L custom

A motor noise under dash after the key is turned and it runs the battery down.

After charging or jump starting the truck it will run. But after sitting the battery drains out again. The Stanley battery box shows the alternator is good. I tapped the starter,checked ground to the starter and block. I also checked fuses and the starter fuse does click and traded it out but still no start.

With the ignition off, I can hear coming from center console below radio a faint humming sound about 3-4 seconds followed by a click, then repeats. Nothing is turned on. Vehicle starts with no issues. Update: two days later battery is drained.

Battery is good, starter and alternator are good, but still wont start. Diagnostic codes P069E and P0463 are present

Oem radio had eject cd running which killed battery. I saw this as a opportunity to replace it and I’m still getting the same issue

This truck runs like a top all summer and fall, in the winter no start, tow over, when we take it to the mechanic in a warm garage starts right up, drive it home, next day forget it. Have tested everything electronic nothing shows up on the diagnostic, have replaced everything known to man, ignition switch, plugs, complete overhaul kept up well and still nothing. Our other vehicle starts right up in the same cold temps...any suggestions? Showing Wife's e-mail below. New Battery. This vehicle is not a Chevy El Dorado don't know why it says it on my vehicle description...is a 2003 GMC Sierra.

So my 1500 started the issue by the red battery light coming on sporadically and then like for 2 or 3 weeks I was having to turn the wheel one way to get it to start but then just boom I had no problems with starting but now whenever you turn the key off and out the headlights will stay on and start flashing. Won't stop unless u disconnect the battery cables. Oh and I also forgot all my gauges started going haywire but now I dont think any of them work properly

Noticed brake lights going on and off while driving while driving for the first couple miles and then they go back to normal operation. Only noticed this once the weather got cold. Then a new symptom developed as the brake lights come on while the truck is off and stay on long enough that it killed the battery. I replaced the brake pedal position sensor and re-calibrated it. Did not fix it. Got another one and did it again just in case. Same problem. No change. Truck is parked for the winter so if anyone has any ideas it would be great to get it fixed before spring.

Dont crank , the battery is good , but won’t crank
