Here's another video update.
PS: I am very wet right now.
It was raining pretty hard, and my wife and I drove over to a restaurant for dinner. I do need to clean the windshield! It's fine for day, but bad glare at night!
My Metro also does NOT have the electric defroster in the rear hatch window. I sure could have used it tonight! In front, I just ran the defroster blower (cold air, no engine heat in this car anymore, remember?) and that worked fine for clearing up the windshield.
I don't think my 18AH SLA 12V accessory battery liked having me running the lights, windshield wipers, and defroster all at once off of it!
I will need to instal a bigger battery or DC/DC converter for the winter.
It also wouldn't hurt to have a dedicated 12V meter strictly for the accessory battery.
I'm just testing all this stuff out so you guys don't have to!!!
PS: So far the GFI hasn't tripped
