ihsig@sbcglobal.net 0 #1 Posted April 26, 2017 308-8 will only start when jumped from a car. Won't crank from a charging pack. I am thinking it's the solenoid. Any thoughts? I last replaced about 10 years ago. Share this post Link to post Share on other sites
N3PUY 1,031 #2 Posted April 26, 2017 are you connecting the jump pack and the cables from the car to the same places? (battery or frame) Share this post Link to post Share on other sites

Jerry77 1,218 #4 Posted April 26, 2017 Sounds like you have a bad ( maybe shorted ) battery--if the solenoid was bad it wouldn't crank from the car battery would it? 1 Share this post Link to post Share on other sites
ihsig@sbcglobal.net 0 #5 Posted April 26, 2017 Brand new battery...forgot to add that part. Share this post Link to post Share on other sites
N3PUY 1,031 #6 Posted April 26, 2017 what is the battery voltage before starting? what is the battery voltage while cranking? what is the battery voltage when running? If the battery is good then it sounds like a poor connection.... at battery or at ground. 1 Share this post Link to post Share on other sites
