We've been having electrical problems, finding the battery

This answer was rated:

We've been having electrical problems, finding the battery drained. One day I found the radio was playing when I opened the door. Unplugged the radio, put on a battery tender and today when I tried to start it, it turns over for a second like normal but won't stay running. The gauges aren't registering, either.
JA: Have you checked the fuse?
Customer: What fuse? Where is it?
JA: What is the model/year of your GM?
Customer: 2004 Silverado 2500 duramaxx hd 6.6 diesel
JA: Are you fixing your Silverado 2500 yourself? What have you tried so far?
Customer: Just the battery tender and replacing one battery.
JA: Anything else you want the Mechanic to know before I connect you?
Customer: No, thanks.

  • Do you own a scan tool to check the modules for codes particularly the BCM?
  • Do you own a DVOM so we can test the ignition switch and do a drain test?

I have neither but I saw a code DODO on the instrument panel, if that helps.

no thank you

Unfortunately, that does not help. In your case, it may be best to tow the vehicle to a shop. For the radio concern, it being on is controlled from 2 things, the ignition switch, and BCM. Either could have failed and resulted in the battery draining, which in turn could have damaged the BCM and instrument cluster. When a draw on a battery kills the battery, the dying battery can cycle on and off rapidly and damage sensitive electronics. I do not recommend any repairs until proper diagnosing has been done.

We were asked if we had 2 technical tools that we don't have, then advised the truck will need to be towed. Not a lot of help. He did mention 2 component possibilities that we were able to research online. He followed up numerous times, but I never responded (shame on me). So at 3.26 am yesterday he sent a text that I didn't hear, but this morning's at 4:34 am I did hear (shame on him, because I couldn't get back to sleep for 1 hour.) Not very professional. The truck? It's still waiting to get it out from under the RV so we can have it towed.

We do not know what time zone customers are on nor where they are in the world. I work till 5 am in the morning and see just as many customers asking questions then as I do when I am online at noon. Sorry, it was a time when you are asleep when I responded.
