    I am going to have a part repaired on my bike by using a welder. My question is do I have to remove any electrical components on the bike so the welding doesn't fry them?
    If you can't find it, grind it

    Hi

    in the past I've had some experence with my Dad and his work mates welding on cars. Remove the battery ! Arc welding causes arcing across gears # it's a subject of great debate.

    Make sure the ground clamp is close to where you're welding and make sure you have a good ground, even if you have to grind some paint off the frame. Never get any electrical or engine parts between the ground and the electrode while welding you can screw up bearings or burn out eletrical components.

    I welded a bottom rail and back brace on the cyclerack and did nothing to battery on the bike, it still runs perfect.

    I had my frame welded with gussets. I pulled the battery, the coil, disconnected or removed anything with a diode in it, and pulled the fuse. The welder knew enough to ground right next to the work, but I was in a belt- and- suspenders mood. Only a few minutes time both in and out. No regrets, but likely overdoing it. If I had been working away from the center of the bike like the rear rack I would not have been so fussy. -GB

    You did the right thing.



    I would rather spend a few minutes pulling plugs than scratching my head trying to find electrical faults and then spending money on something that failed because I was too lazy to do it right.

    Thanks. The diode idea was my own. Anybody else have a thought about their vulnerability? I took off the coil since it was to close, nothing more.

    I welded my XT tank mount on. The battery ground wasn't connected but that was because I was working on the electrics, not because of the welding. I did happen to ground on the piece I was welding on. Since I am a poor welder I had to grind the welds off and re-weld in a couple of places. Everything still works.
    Long live the internal combustion engine!
