    I have done some research about installing a secondary battery and isolator. I'm new to this so, I have a few questions. I have a '02 Trailblazer EXT. I am going to be running some things for about 3 to 4 hours or so without the engine running. Here is what I am going to be running, a 50watt...

    Hi everyone, I didn't see a specific thread dedicated to electrical, so I hope I'm posting in the right place. A few nights ago, I was driving home. Had been on the road about 5 minutes. Suddenly, the radio dies, guages on the dash die (Oil Pressure, Fuel, Temp, Voltmeter), Tach and Speedo keep...

    I've got a 2005 GMC Envoy XL. It use to be that if it wasn't driven for a week the battery would die. Now the battery dies in less than 24 hours after being driven. It does have an aftermarket head unit as well as an overhead DVD player, both installed by a 3rd party, through the dealer when...

    Ok, I know there are many threads out there about dead batteries, but I haven't found any with specifically like what my '02 Envoy XL is doing. My battery (now replaced for the third time) has a slow drain that causes the vehicle to start slowly after sitting 4 days. If you let the Envoy sit...

    I went to start my 06 this morning and it wouldn't turn over. All of the cluster warning lights turn on like normal....when i tried to turn it over the first time it started, all the lights stayed on, then it died. I tried a second time and got next to nothing out of it, and it made a rumbling...

    Here's one for you: I have had a drain on my 2004 Trailblazer battery for the last year and finally figured it out this past Saturday!!! (no extra cash to take it somewhere) So I have had a 6.4 amp draw on my battery and replaced the battery once. Everything tests fine (battery, alt, etc) yet...

    A couple of weeks ago I blew a fuse in the box under the hood that kept the engine from starting. This happened a couple of times but no one seemed to know what was causing the problem. I bought a box of fuses and did not pursue the problem because I was having other health related problems...

    Hi All, This is my first post on this site. What a great place! I have an 02 GMC Envoy with the 4.2L. Where I live, it's been -20-30 degrees below zero. When I start my truck in the morning, the battery stays at about 9-10 volts for about 10 seconds. My lights and blower motor are barely...

    I would like to know how to program my remote to unlock all doors on my '07 LS with a single press of my OEM Keyfob. As a salesperson, I carry my stuff in the back seat everywhere I go. Because I have to press the unlock button twice every single time I get into my car, my battery life and...

    Removed the battery cable and replaced mid-gate regulator with a new one as it had jumped track and twisted up. Put battery cable back on and tried to start. Motor starts for about 2-3 seconds then dies. I noticed the radio comes on during this 2-3 seconds and then goes out. The windows do the...

    I took my 04 TB into the shop because the battery would go dead if not driven for a couple of days. Prior to this, I was experiencing some performance issues (rough idle, lower fuel mileage, shifting at higher RPM in low gears, etc). I think the battery might have had a bad cell (brand new 6...

    This has been as problem for a little while now that tonight got much worse. I used to think it was just my eyes playing tricks. I'd get a flicker and then it was gone. Tonight it was just going crazy! While costing or decelerating from a highway speed my dash lights and dome lights flicker...

    My 04 TB was making a strange noise when I turned the engine off; a whining or winding noise similar to a jet engine shutting down is the best I can describe it. My mechanic said the bearing in the AIR pump was bad and the pump needed to be replaced. Despite a hefty bill, replacing the pump...
