For the last four days I’ve been looking for an electrical fault, the headlight stopped working.
This is what I’ve got…
> Rear light, break lights, dash lights, and indicators are all working correctly, except the headlight. But, Hook the bulb up to a battery, works OK
> With the bulb IN the holder - high beam light on the dash is permanently ON with the switch in either position, headlight not working.
> With the bulb OUT the high beam light on the dash works in either position
From the manual I’ve done the following
(A) Continuity test on the switch and it only passes 1 out of 2 tests
Brown and Yellow [PASS] high beam
Brown and Green [FAIL] low beam
(B voltage) Switch at high. With the bulb in the holder, and the switch gear plugged in; using a meter on the holder it does this. + to the yellow (high beam) and – to black I get the correct voltage reading AND the bulb lights up on high
Switch at low + to the green (low beam) and – to black I get the correct voltage reading and the bulb lights on dipped
(C) With the bulb in the holder, and the switch gear unplugged; + to the yellow (high beam) and – to black in the connector block I get NO voltage
At this point I mail Dave Lambeth who say’s “it’s probably not the switch but a damaged wire” So I cut all the shrink wrap away, start looking and find nothing obvious. However, the use of electrical tape on the wires and connection blocks under the tank suggest, someone has been doing stuff.
I figured I’d unplug the back light, fire the bike up, and check if the headlight still worked using the meter as before but, with no backlight inline.
Flat battery, that’s not surprising. I’ve been starting the engine then killing it leaving the lighting circuit on a lot over the last couple days. Charged the battery, pushed the button, didn’t fire. Killed the battery, recharged it, and it’s the same, won’t start.
OK I said to myself, it’s electrical. What stops it starting? So, I tested the side stand, clutch, and neutral switches, all OK.
The one thing I did notice yesterday after the first try was the oil level; I could just see it in the glass, which is unusual when the bikes been stood for a couple weeks. Today when I look, the oil level is right up, as if I’ve just been riding????
Now I’m thinking, F
K it’s not electrical
