Question about Yamaha Royal Star Venture Motorcycles
Okay...when you say power to the coil...I think you mean getting a spark on the plug wire?
All 4 coils should have battery voltage on the red/white wire to each coil. The second wire returns to the igniter (TCI....ignition black box) and it switches that wire off and on to ground to cause the coils to fire. If all 4 test good...then
Check out the TCI, the large box mounted on the coil rack that the connectors are clean.
Now remove the 6 wire connector from the TCI...and test the resistance of the pickup coils which are located under the left crankcase cover beside the stator coil.
you will be testing the following wire pairs on the 6 wire connector
You should see at ambient engine temp...about 110 ohms resistance on all 4 pairs.....if one pair is showing no resistance...you need to test at the lower 5 wire connector just below the seat left side with the same 5 colors....unhook and test....if still having one bad test...pickup coils may be bad.
