Hey all,
I have been rebuilding a 288. I have been thru this thing top to bottom, almost.
It came to me a non runner with no comp. I am to the point of putting it all back together, and now have no spark. Brand new plug. How can I tell which is faulty, the coil or the module?
Thanks for lookin.

IMHE, it is the module, mounted on the right rear of the saw.

Hey thanks! Is this a problem spot on these saws?
Oh, and one more important piece of info. This saw came to me with no flywheel. I finally found one , it is off of a 181(same p/n i think?) I should not have to use a coil from a 181. Or do I?
Thanks

Depending on which model of 181 (SE or SG) there were two flywheels used
501 80 22-01 (SE)
501 80 22-02 (SG)
(SG) being for a generator for heated handles. Both the 281 and 288 also used the same part numbers. There are two parts to the ignition system 501 81 27-02 & 501 81 28-01 being the electronic box and the coil respectively. Make sure you do not have the wires going to the wrong places, IIRC there is a red wire that goes from the electronics box to the coil and a blue or black that goes to the on/off switch. Also, check to see that none of the wiring is grounding out on the case. They have different size connectors so it is easy to get them where they belong. You can get factory replacements for both parts of the coil as well as aftermarket.

Module to flywheel air gap should be 0.3mm or 0.012, use a business card to set the gap. Either half of the ignition system can fail, it is a 50/50 deal but in my experience it is more often the coil itself. Both parts are stupid expensive. I do not know of a good way to check the individual parts, and I don't have a complete one here.

I bought an aftermarket one from Northwoods and it seemed to work great. About half the price of OEM.

Thanks KRL and Gatekeeper! I just wanted
The flywheel used is from a 181 se. It has the correct p/n stamped on it(22-01)
Air gap is. 014 . Yes you are absolutely correct, "stupid expensive"is the perfect description. Hence this post. I just wanted to pick someone's brain before I dropped that kind of $$. Much appreciated !!
Looks like another trip to NWS.

IIRC, HVA used a couple different manufacturers for the two piece ignition systems, parts cannot be interchanged between the different types from different manufacturers. So you will probably have to buy the whole thing at $45!

Anybody know where Northwoods saw is located?
