@flhr05 posted:bmoran4, I know this thread is from a couple years ago, but did you find out the problem. I have a 2354 doing the same thing and was hoping to find a resolution.
Thanks,..
This is an old thread revival. Unfortunately, I have not found a satisfactory solution as of yet and so I just have lived with it, limiting their run time until I decide again to tackle this. Not sure what that will involve as I have done quite a bit of throwing parts at it already, but like others have advised, I may start disconnecting everything and then one by one connect things up and see if I can narrow the sparking to the inclusion of a specific component (a motor, e-unit, horn relay and so on).
I don't immediately recall if I have checked these for loose motor field rivets, that is another possibility.
