Hi! Anybody here who knows if there is any Connections or so needs to be disconnected before welding on the machine?

I always disconnect batteries and cdi any time I'm welding on anything.

I have welded with and without the battery or ecu connections disconnected. I would always suggest placing your ground as close to the weld as possible to protect any potential issues..

I usually disconnect the battery and just like rick said put the ground close to where the welding is taking place.

same as what they said, just have the ground as close to the weld as you can, and disconnect all important electronics.

As long as both battery cables are disconnected, you will be fine.

Factory service manual stated to always disconnect the ECM. Its an additional fifteen minutes to disconnect it so why not?

I've welded on hundreds, and I do mean hundreds of vehicles including my own CL65 and have never once disconnected a battery or ECU to mig weld on a vehicle. Never had an issue (OK, once caught a Camaro on fire, long story) but no electrical issues. I'm not afraid to weld on my own $180K Mercedes with 8 computers so I don't think you should you be worried about your ATV.

I just happened to be welding on my 550 this weekend. did not disconnect my battery and everything just fine.

U don't need to disconnect anything because the current only goes from the ground to where you are welding

I would unplug the ecu so don't mess it up. Cheap insurance!!

It doesn't hurt to disconnect the + & - leads of the battery. Also doesn't hurt to disconnect the ECU. Sure, it might take you an extra 15 minutes or so, but on the off chance that something goes awry... You'll be wishing you had....

The ECU on the XP's is mounted on the upper frame crossmember in front of the radiator. You can see part of it in the lower left corner of this pic. I believe you should be able to disconnect the plug on the ECU itself... Never tried it though.

Sorry jgcoastie's

That is the voltage regulator/rectifier

The ECU is mounted on the left side of the air box under the plastic

x2, left side the airbox, should have a metal housing on it with a Bosch sticker I believe.
