Confirmed: My starter solenoid doesn't like -20 and colder
she'll start no problem in warmer than -20,.. but any colder and I have to crawl under the jeep and jump the 3 terminals to start it,.. bastard starter,.. I have a bad one in the garage with a good solenoid,.. but I hate working outside (besides I need a sitter to watch my baby - wifey got a morning job)
