Thought I'd start a new thread about this. As you may know, disconnecting the battery on a TB may or may not result in your computer reset process breaking one of the HVAC actuator doors. That will cost you. It cost me. I talked with the dealer and they always hook up a 'computer memory retention' tool to prevent this and other bad things happening when you have to disconnect the battery. Here is a Youtube about this: Trailblazer battery disconnect - side effects - YouTube
I don't have the tool, but I am thinking that this homemade tool would work fine.
neg.battery.clip ----------------- neg.post.9V.battery pos.post.9V.battery ------------- diode-> ------------------- pos.battery.clip
attach the pos.battery.clip to the positive post on the battery; connect the neg.battery.clip to a good ground. Remove the negative battery cable. Do whatever. Replace cable. Remove my patented (ha) memory sustainer.
The diode would keep the 12V current from flowing backwards through the 9V battery and potentially blowing it up/ruining it.
Good idea? Bad idea?
