Welding / electrics Question

[mod4]

Need to weld on my fairing support, I'd LIKE to do it with it in place.
My limited experince in the auto world has shown me sometimes just
disconnecting the battery is NOT enough to prevent system damage.
(mig welder).

Can any of the guru's on here tell me what I need to do to make sure that I don't fry anything ?

Thanks in advance.

Hmmm
It is possible you could create an EMP..

I think pulling the ignition module and disconnecting the battery would be enough..

Well, a couple things come to mind... First of all, the welds (and the metal you expose to weld to) will need to be coated to prevent them from rusting like the dickens. Powder-coating is the usual method after welding, if you want to take it back to factory-like status, in which case you're stripping the bike apart anyway so the frame can be powder-coated (because powdercoating involves placing the frame in an oven after application).

But, if you were to weld in place, here's what I would do:
Disconnect the battery, and pull the pigtails at the CDi and the dash (plus at the TPS on the 98+ Kats). I'd pull the CDi and the coils to be on the safe side... if not, lay plastic wrap atop aluminum foil, and with the plastic facing inwards, wrap the CDI and anything else you don't want picking up the EMF... The aluminum foil should act as a faraday cage to catch the EMF, and the plastic will keep it from being transmitted into any contacts underneath by contact.

The thing you really want to do is put the welding machine physically as far away from the bike as possible, because almost all the EMF will be coming from the welding machine -- not the head of the welder.

most welding supply shops sell a "tool" that connects to your battery and it is made to stop that problem

Very good point!!

you could simply ground the bike.

That won't protect it from EMP or EMF

Same here. Works on cars too. Disconnect Battery and unplug ECU.

When I did my subframe repair last week, the battery was disconnected, as was the CDI. The harness was still attached to the bike, though it wasn't connected to much.

We also repaired a couple small spots on a 2005 ZX10 with GTAW, and I don't think there were any problems - we just yoinked the battery and unplugged all the ECU connections.

Make sure you have a good ground and that it's as close to the area you are welding as possible. You shouldn't have any issues.
