I. Test headlight bulb. Measure resistance across bulb-terminals. Should not be open-circuit/infinite resistance. Also test by connecting power directly from battery terminals to bulb terminals using jumper-cables or test-leads w/alligator clips.
TEST PASSED
II. Test headlight fuse #5. Don't just look at it, electronically measure for continuity/resistance between two legs. Should be zero-ohms/full continuity.
TEST PASSED
III. Test headlight-socket ground. Measure continuity/resistance between ground-terminal of light-socket plug and chassis-ground. Should be zero-ohms or full continuity.
TEST PASSED
IV. Test for power at various points along headlight-circuit:
1. measure for +12v @ battery positive terminal
TEST PASSED
2. measure for +12v going into headlight relay
TEST PASSED
3. measure for +12v going out of headlight relay when bike's running if yes, skip to #7
TEST FAILED
4. measure for +12v going to headlight relay activation line when bike's running
WHICH COLOR WIRE IS THIS?
5. measure for +12v going out of start/stop-switch to headlight relay when bike's running
TEST PASSED
6. measure for +12v going into start/stop-switch
TEST PASSED
7. measure for +12v at positive terminal of light-bulb plug TEST FAILED
If I remove the headlight relay and jump from the grey wire to the blue/yellow wire the headlights will work. Tried about 6 different relays all with the same result.
