I need to weld a nut on the end of my side stand bracket, so the spring won't ping of.
I would be arcing, for that is what I have/do.

Do I need to disconnect my ECU unit to prevent any damage here?

Ta chaps.

I'd disconnect it, remove it and put it under my bed for safe keeping
Can't be too careful, 5 mins of unplugging may save you a couple of hundred quid and a few weeks off the road.
Whilst it may be OK to weld with the whole system connected it's never worth the risk in my book.

Thanks for the advice Andy.
A fine idea too.

+1 BUT also encase it in lead, then bubble wrap.

+ 1 fill the bubble wrap with an inert gas.

+1, then surround the entire area with a rather large fence, with barbed wire along the top. A moat is possible if your bedroom is downstairs

Make sure you disconnect the alternator, voltage regulator, coil.................everything that has an earth.

I welded a sidestand on a friends GT185 bike a many years ago, the wiring loom melted and nearly caught fire when we pressed the starter button afterwards.

Purely a coincidence you understand.

Right about now tapping a thread on there is sounding mighty attractive.
Mike

Yeah, you know what?

I might shelve the welding bit. Tapping and glueing seems more attractive.

No contacts with a little gas set?
Mike

Not really Mike.

Its not critical anyway. The nut has stayed on wedged against the frame guard, just wanted to make it a bit more permanent.
