Cut off switch shocking??

[se3388]

I have a Super XL and it runs fine since I got the new fuel line and filter from parkinparts but when you turn the ignition (off/on switch) off it gives you a shock (it did it before the new line also). I thought I would ask the more qualified where I should start first.

The kill switch that is shocking you actually grounds the primary side of the coil to stop the spark, thus killing the engine. If the switch is bad internally or not tight and grounded to its mounting surface you can get a pretty good shock. I would remove the switch and clean and shine up the mounting surface,scrape the paint off to bare metal and make sure it is tightend up snugly. If you still get a shock, replace the switch. Also check the wire from the kill switch to the coil and make sure it is not pinched or bare anywhere while you are in their and clean out all the accumulated saw dust also.

Thanks, that is kind of what I was thinking but having never worked on a saw before I deferred the experts. I have taken apart and worked on just about any thing that runs at least once.

Hi pauldent,

Welcome to the House of Homelite!

I don't know much about the 330 but looking at an IPL for the 330, there appears to only be one wire shown.

Maybe someone else will be more helpful. Post the UT number and serial number or better yet a pic of the number plate, that would be very helpful getting the right information to you.

Hi Pauldent,

Later models ran a separate lead for grounding the switch...the diagram above does show this, but it's deceiving as the kill switch wire to the coi lis not shown in Figure 1. The lead that is shown goes under the engine housing and is secured by one screw to the engine block for good grounding. It is important to get the wires correctly mounted...the lead from the coil (thinner lead) goes to the terminal on the switch and fatter ground lead goes to the tang that grounds the switch body.

Hope this helps!
