Another item sleep mode item is confirmed. The temp/radio mini fan does turn off after a few minutes. Next test, unplug the passenger side door switch. I have yet to use my clamp meter to check the ohm draw. The Foxwell does give reading info to know for testing. I’ll update when tests are completed.

Today, I couldn't finish testing. However, I noticed the green left side switch light was on after 11.5 minutes. Does anyone know when the green light should turn off? The light is the rear window lock out button. I'm starting to wonder if the light is the Foxwell "Deactivation criterion for window operation: error".

It's been 6 days now. No trickle charge overnight. The GMIII repair dropped amps low enough not to drain the battery. The Foxwell helped troubleshoot by forcing it to sleep. Now to fix the P light and interior lights.
