Re: 01 929rr dies/shuts off while riding
Mag has no separation of heat and chemRe. So even if you tightened the cables, under the contact points, a chemical reaction is happening to the ground side more than the hot side.
With a straight razor, scrape the top of the battery post and the bottom of the cable end it contacts with. If the ground cable is white with corrosion, then dip that in a cup of vinegar and wait for the bubbling to end, clean with brake or contact cleaner, water, etc.
With lights still on, it's making contact yes, but how much contact at that resistance point?
