Motorcycle Repair: 85 honda shadow no spark, honda shadow 750, 4 ohms

Question
I have a 85 honda shadow 750 . I am getting power in and out of the coils . there is no spark at all . someone said the pulsers but there is no spark in any of the spark plugs. I have checked all 4 of them .

Answer
If the coils are okay, the spark boxes could be the problem or the pulse generators.  You can check the pulse generator with a VOM.  They should have 3.4 ohms or there abouts.  If they have the right resistance, it's probably the spark boxes under the seat.  Just make sure you have voltage to the spark boxes before you replace them to be sure it's not some other problem.
