Question about GMC Sierra
I keep boosting car then battery goes dead
Perhaps your alternator is faulty or drive belt slipping or battery could be faulty.
Check battery connections and main earth strap.
Have battery tested and then check voltage goes up as you rev up to see if it's charging. (should reach 14.5v)
If there are no warning lights the battery is the prime candidate

I think you may have destroyed your battery or the electronics?
First check your fuses are all good
If that don't fix it.
Check the voltage of battery Red to + Black to -
Meter should give a positive reading say 12-14Volts DC
If this is what you get then you may need a Auto-electrician to check electronics and wiring.

Hello, I have found that if the car shows any sign of a dead battery like a slow crank it will pop the trunk. I dont know why they do this but mine did the same thing when the battery was bad

if voltage reulator on alt. does not stop current after battery is charged it will over charge battery abd can drain cell from boiling electrolite out.check 4 bulged battery case(swelling) indication of overchaeging.the start problem could be your starter wires connection.remove starter wires clean contacts and torque respectively.dont forget the ground to motor.sounds like a loose or corroded contact somewhere.

You need to find the current drain. Charge the battery, then disconnect the Negative terminal. Now connect a 12v tester or a automotive lamp between the terminal and the battery post. This will put the tester/lamp in series with the current flow and they will light if there is any current drain. So assumming the light is on, now pull fuses one at a time until the light goes out. Remember to keep the door light switch from being activated as that will cause it's own current flow. Do not turn on the ingition since the failure happened over night while the truck was off and closed. There will be a normal very small current flow all the time to power the radio preset memory and perhaps an alarm but that flow will barely light the lamp. If the lamp is blown due to a real high current flow then you will neet an ammeter with about a 50 amp current rating.

You have what we call a parasatic load(aka battery drain). If your handy with a volt meter I'll explain to you how to locate your drain. If not I recommend you take it to a repair shop and have then locate the drain.
let me know.

Welcome to FIxYa.com
Check for a drain remove the positive side battery connect a test light clamp end to the battery wire and the pointed end to battery post light will be on. Pull one fuse at a time. When test light :light goes out that is the circuit draining the battery
