While were at it, electronic cars should not be running when you give someone a boost, jumps in voltage or a dead short could fry YOUR computer or lots of other stuff. Tow trucks have separate isolated batteries for boosting because of this.

The first part I'm saying that an electronic engine may not run without a battery because the voltage is not right. Power coming from the alternator normally is ? stabilized by the battery or made a constant 12.5 volts or whatever. With the frozen dead battery the voltage could be all over the place 15-13.5 12.3 10 ?? I said the cars electronics might not work proper because of it.
Then I'm talking about voltage spikes, dead shorting and load dumping on a cars alternator and electronics while boosting. I'm clearly saying it's a bad idea to have your good engine running while connecting, disconnecting and starting the dead car.
What it costs these days to fix cars, I thought some CP'ers might appreciate my opinion, especially the poster who's situation I was directly talking about.
Comparing a sudden voltage spike when boosting, to running multiple alternators in parallel (who does that) just for the purpose of disagreeing with me to get under my skin is pretty lame. You too Jimmy Lame.
