Any electronic will burn out with the ign left on. I do tons of this stuff and have tested alot of different systems. A typical mopar ECU draws 4 amps on not running and 2.5 amps running for example. Similar I will only use the I in my rebuilds, the II and III have had to many fail right out of the box to trust them. Yeah Carters colant was ot great at all. You almost always have to run a return line with them. I use a aeroquip? in mine probably miss spelled it. Cool car by the way, had a chance to buy a intercepter years ago with a blown motor for 800 USD, dumb kid I was for not doing it!
