You might want to try a couple of things . Make a post here .
http://forums.sohc4.net/index.php?board=113.0Ask for opinions regarding what your running noting the 2.2 ohm coils and your problems .
Second , P.M. MRieck and ask him for advice . He has posted in the past with regards to Dyna 2000 . I'm positive he uses it on his machine .
If you end up getting a new harness don't automatically assume your problem is fixed . You might fry a new harness . A relay bypass for your coils is cheap and easy to do and will protect your harness . If Hondaman says 2.2 ohm coils won't work on your bike I'd believe him . He has a background in electronic engineering and failure analysis . I wonder if a resistor in series with the coils wouldn't solve the high current draw problem without the need to replace the coils ( if the people you bought from won't swap them ) .
Here's some info on the relay bypass .
