    Bad Battery and OBD Codes

    Bad Batteries and OBD Codes. Check your battery first if your Escalade is pulling electrical related OBD codes. I just purchased a used car for my son. As is my habit when purchasing a used car, I reviewed the Carfax and ran an OBD diagnostic. I noticed on the Carfax the battery had just been...

    Fix For Head Unit Receiver causing Parasitic drain?

    Thank you all for the suggestions. I took it to the shop which previously worked on the radio. They found a bad relay in the aftermarket harness was intermittently arming and producing the drain.

    Fix For Head Unit Receiver causing Parasitic drain?

    The radio was installed in 2021. I didn't notice a problem until about a month ago.

    Fix For Head Unit Receiver causing Parasitic drain?

    Does the fact the radio shuts down correctly when ignition is turned off and the drain doesn’t begin for a while after its off mean the problem is more likely in the head unit? People who installed it think the “sleep mode” logic in the head unit my be malfunctioning.

    Fix For Head Unit Receiver causing Parasitic drain?

    So we finally found the source of the parastic battery drain. It's the Pioneer AVIC8400 stereo head unit. But why it's happening is still a mystery. The drain is about 2amps. By removing fuses we found about half is from the head unit and the remainder is from the Bose amp. The kicker is that it...

    Remote battery disconnect switch

    I disconnected the starter solinoid and drain remains. Also checked alternatior and connections, same. What I'm asking for is advice on a good, reliable remote battery disconnect switch I can install until I can get the truck to an electric repair shop. There are only two in our area, and both...

    Remote battery disconnect switch

    Nothing was added or changed immediately before the drain got bad enough to not start the car when it sat overnight. It started about 3 weeks ago. The last electrical issue was the HVAC blower motor control module failed. That was about 3 or 4 months back. But with HVAC fuse removed the drain...

    Remote battery disconnect switch

    I've had the battery checked 3 times. It checks ok. I even fully charged it outside the truck and left it overnight which is the time it takes to drain when connected to the truck. The next morning the battery was still fully charged. I think I had my decimal point in the wrong place on original...

    Remote battery disconnect switch

    I'm having an issue with a parasitic drain of 110-170mA which I can't find. It Does Not Appear to be Fuse Related, as we removed all fuses, and the drain continues. Also, the drain doesn't cycle. It is always at least 110mA. I can't get it checked out by a shop before the end of March due to a...

    Little help with electrical issue

    Thanks for the input. Here is where I'm at: 1. I recently had the battery tested and it was good. 2. Just took delivery on a new alternator which I'll install later today. 3. The cluster was rebuilt about 2 years ago. 4. The main ground from firewall to engine may be an issue. I'll check it. I...

    Little help with electrical issue

    Yeah, I think a parasitic drain test and search is next. But that's something I'll have to pay to get done. I don't see well enough to test leads on individual fuses.
