Posted this on XS650 Garage, too...
My bike is kick-only (only because the starter doesn't work - I think this is a solenoid problem), and has been converted to a GM HEI ignition by a previous owner.
Borrowing 12v from a car battery, I get 12v at the red wire on the coil, but no spark. The coil reads .6 ohms, which other threads say is right.
I have a spare coil and a spare HEI unit, both of which I have swapped in with no effect. Also built and installed a Radioshack rectifier, and I have the Chrysler regulator on hand, but haven't installed it.
Another puzzler - the HEI unit did not appear to be grounded (it was mounted to the battery box) even while the bike ran well. Also can't figure out if there's supposed to be a condenser with it.
I put my meter between the coil and a plug, kicked it, and got nothing. Not sure if this is a resonable testing method, but I tried to just hold a gap for the spark and got nothing.
I'm not sure how the new HEI pickup works, or how to test it, and I can't find anything about how to test the HEI unit itself.
Wit's end is long gone, and and help will be much appreciated.
