My saw is broke....

[RobertN]

You would need a volt-ohm meter. It would be used to measure resistance; the wire and switch should have little to none. I hate to see you buy a coil, without knowing if it is really maybe a bad wire, switch, or connector.

Definitely store the saw in a cool dry place, on a shelf. Letting it sit on gravel or concrete, will cause the aluminum to break down. Seen some pictures of saws that sat on gravel; over time it ate thru the crankcase.

It sounds like you may have a bad wire connector and the moisture is making it worse...

I am going to check that wire also, the saw sits on my damp gravel garage floor and it wont start or acts funny. I left it on my porch over night and just tried to start it and it did try to fire. Have no idea how to ohm out the wire to check it? Also wouldn't the saw have to be able to run to check that?

I found my meter now what do I do? Not even sure where the ohm is on it? Is that the upside down horse shoe looking thing?

It is the upside down horse shoe.

If you have you meter, set to ohms, and check a good piece of wire(touch the meter leads to either end of the wire), it should read 0 ohms, or very very close to it. If there is a break in the wire, it would read lots of ohms(resistance).

For instance, if you measure from where the wire connects to the switch, over to where it connects to the coil there should be 0 ohms.

With the switch on, you should be able to read from ground/chassis up to the wire connection at the coil. It should be 0 or close to that. If you turn the switch off, then the ohm should read extremely high(open circuit). At least, that is the case with my older Stihl.

Excellent I will give that a try tomorrow! Thanks for explaining it so well!!!!

I just check everything on the saw, the wire keeps coming back at "0.00" when I touch the one end by the switch to the other end by the coil. Does this mean that it probably is the coil?

I'm not a electric type. So I cant help at all. Hopefully the guy in the know can help you.
Me it either works or it dont and I replace with known good coil to find out.

Dont make me send you this 026 pro with domed piston and woods porting running 16" 3/8 RSC in video. But now wearing 20" .325 RSC.

Video of first cuts and first tank of fuel after putting together.

That's a cool video! Was that a hard wood or soft? Im gonna take my saw back to the place I bought it from originally tomorrow. They told me Saturday that the mechanic can check the coil and see if it is bad or not. I tried to fire the saw today and it didn't even try to fire. Oh yeah if you want me to break it in that 026 for you, I'll email you my address! My saw when its running right used to cut wood at a good pace....

Oh I know the 361 cuts goooooood.

That was just soft poplar I have on hand. It cuts just as good in the ash, elm, oak it was in today with the 325 20.

Dang! I noticed you didn't ask for my address.... Do you notice a big difference with the domed piston and porting? Have you ever seen or used a 361 with the same set up? Just curios??

0.00 means there is no resistance(good!). It will say OL or some other high number if the leads are not touching anything or the circuit you are testing is "open"

What are you reading with the switch in the "off" position?
Disconnect the wire from the coil and do the test again, you could have a short in the coil and are reading thru it instead of the wiring.
