I was checking something in my Stihl 440 server manual today regarding the ignition module . It starts this topic with a warning of the high voltages that can cause "serious or even fatal accidents". Like most folks on this site, I know not to hold on to the spark plug while checking for spark. Maybe 20,000 volts !!!

But I am not sure of what else "not to do". If I need to remove the IM, I always pull the spark plug wire first. The IM is not a capacitor so it retains no energy/charge. Agree ? What are the rules when working with this part ?

Time permitting next week, I want to take two junk saws apart and build one working saw, and live to brag about it.
 
They made it sound so serious that I was afraid of the "unknowns". I did not want to be known as "sparky", in the past tense form.

More good advice from Andy.
thanks
 
There is so much liability limiting language in manuals these days it's amazing that anyone attempts to do anything................
 
Andy:

Is there any shock potential directly from the ignition module, or is it only when connected to the spark plug ?

Or, put it this way, if the spark plug wire is connected, and you manual spin the fly wheel, is there a shock potential it your hand is on/near the IM ?
 
AD:
I agree and was not sure of how much of this wording was "PYA". Good point, but for my own safety, I wanted to post on A/S.
 
Jeeze, I've sorta come to enjoy hangin' on to the spark plug while checking the electronics! You guys sure know how to take the fun out things....
 
RBW: Ditch that coffee and try a can of "full throttle". It will calm you down so you can handle these Chainsaw-101 type questions.
