I have had to start the 1502 with one of those little lithium ion jump starter packs every time. I have yet to trace it back to the battery or the alternator. I’m suspecting the alternator as the battery is supposedly new. So it starts with the battery pack, but when I try to jump it with another car, its like the battery is more dead then when I try without it... Any idea why? I’m asking mainly because im trying to take it for a quick spin before I put the exhaust on and the battery pack is dead and takes forever to charge!
UPDATE: I just needed to let it charge for a few minutes as a few of you suggested. Thanks!!
