    The kill circuit is a grounding of coil. It has no switch. This system has been used on many other saws thru the years.
    It could be you don't get contact between cable on lever and plate on air filter bracket.
    I changed a few coils on newer HVA saws as the circuit inside coil is busted.
    But its more common with contact and cables.

    FINALLY! I registered yesterday just to reply to this thread and it took until now to get approved! The 576 kill switch consists of 2 wires, one blue coming from the coil, and a black wire that goes to ground. They both sit inside a plastic holder and when you turn the switch to off it completes a circuit killing the coil.

    It is not a switch per say, as there is a lever were cable end sit and a plate it grounds to on airfilter holder.

    Well, for now anyway, the Treehouse fixed my saw.

    Thanks all for the responses. Magnus' and Huntaholic posts got me thinking about the contact area. As mentioned in the OP, it is kept clean in there, but on a hunch I decided to spray alcohol onto the contact area. Fired it up and tested it 4x, worked perfect.

    What happens is those little end terminals, especially on the ground wire get sloppy in the plastic holder and fail to make connection. I will take a small screwdriver and open them up a tad to fit tighter in the plastic housing. Ive got 4 or 5 of the 575/576 saws right now and have worn out at least that many more lol

    The idea with contact surface like this is not bad, but it has its downsides.
    The contact can get bad even if its clean from erosion or corrosion.
    A thin layer of oil will do the trick to!
