ws... Welcome. FIRST... Murphy's law rules when buying parts from eBay. There is often a REASON why folks are selling electrical bits... you might want to see if they appear to be parting out a whole bike or just selling their old igniter! bwhahahahaha
I have bought toooooo many junk electrical parts off eBay and have become a bit jaded I guess... I doubt your multimeter stopped working when you made the eBay purchase.
I don't know much about your model but if your bike turns over and you get no spark, first thing I would check is voltage at the coils. Each of your coils has two smaller wires connected. One is the wire from the IC Igniter that carries a "signal" and the other is the wire from the IC Igniter that carries voltage. If you turn the key on and check for DC voltage at the coil, you should get about 12.4 VDC. I am not sure of your wire colors but you could just put the NEG probe from the multimeter on the frame and the POS, red probe on each of the lugs. If you don't see voltage on either lug carrying the wires from the igniter, this is your problem. You have a break in the electrical path and I can help you troubleshoot this...
OK, if you do have voltage at the coils, you have either faulty pickup coils, faulty igniter or faulty ignition coils. Check for spark on both the #3 plug and the #4 plug. This will tell you if you have spark from EITHER coil. If there is spark from one but not the other, I would check the coils and primary leads (plug wires/caps). If I had no spark on EITHER #3 or #4, then I would look at the igniter. If you find spark on one side, let me know and I will tell you how to check the coils. They do short with age and plug wires DO go bad.
Based on your troubleshooting thus far, if you do suspect a problem in either the igniter or pickup coil, it is more likely the igniter if you have spark on neither coil. The pickup coils tend to go bad individually where one will work and one won't.
If you suspect the multimeter, check the values suggested by your manual. If they don't jive, check the old igniter and repeat the tests. If you seem to have purchased a defective igniter from eBay, then you MIGHT want to think about a Dyna S. They are very inexpensive now (compared to what they used to be). You might also want to pick up an older style mechanical advance with timing marks already in place for the 2/3 cylinders. That can be had from eBay and I would look at
www.z1enterprises.com for a great price on the Dyna S.
