[QUOTE="wfooshee, post: 1455510, member: 6354"] Starter load should be 65 to 85 amps in the bike. On a bench, probably 30 to 35 amps. I had a bad starter that pegged my ammeter's 160-amp scale. Bike would start with a jump but not from the bike's battery, especially when warm. Stone cold, it would start OK most of the time. I haven't seen anyone post that this was solved, so my 2-cents worth. Loose or corroded contacts at the battery connectors. When jumped, the wires from the other battery have good contact with the bike's wires, resulting in an easy start. Bad battery in the first place, no cranking capacity so voltage drops severely under load; same thing, jumping bypasses the issue. The bike will start with [I]much[/I] smaller jump wires than should be used, as they'll carry the extra current needed for the few seconds needed, without bursting into flames. I've jumped mine through the battery tender leads. [/QUOTE]
