Hey I was wondering when I would hear from you. There should be some kind of reading across the two spring terminals and from each terminal to the spark boot on a good transformer. I'll get mine out and mess with it next time I get a chance.

Thanks Dan, I have several transformers that I need to find out if they're OK or not. As far as the other module, we have a Graham coil tester that would should work, I haven't tried it with the 360 module but I've tested SXL coils with it.
I am at a bit of a standstill with my 360. I can't seem to find the problem with the ignition, and aa Dan pointed out theres no good way to check the module with a multitester, I already tried a simple continuity check and it was inconclusive. I've already stuck a lot of time and about $30 into my "free" 360 and I don't want it to beat me! I'll try the transformer test shown above and go from there.

angel, one more thing to check is the transformer receptacle where the transformer screws into. One lead on it should be a ground reference and the other comes from the trigger module. I've found a couple of times where the spring leaves on the transformer were not contacting the receptacle and caused no spark. Also, its good to make sure the ignition switch doesn't have a short to ground when in the "on" position. Don't give up, 'casuse these are great saws! Dan
In addition to what Dan just mentioned theres this. The 350/360/450/550 all ground one side of the transformer to the chassis via direct contact between the chassis and the transformer mount. The case on these saws is often corroded in this area and the system will lose ground as a result.
I take a jumper wire and the correct terminals and jump from the ground side screw to the cylinder or case directly as is done from the factory on the 650/750.
I Solved some reliability gremlins this way on my 450.
