Head light issues
 

If anybody could give me a hint would be much appreciated , I have power to my headlight switch ( all I have is a test light ) when I turn the headlight switch on the power pretty much disappears ( very faint light on the the tester) could this be a ground issue . Thanks in advance

Some info on the bike might help. Does it fail with only your test light hooked up? The little contact shoe inside the switch may not be making a good connection.

The switch is brand new, It's the same result with old and new switch.. I have 3 bulbs that I have been testing with unless they are all burnt.

The most likely cause is a broken wire somewhere. This usually happens to the wires beside the headstock from flexing as the handlebars turn. Trace back through the cover tube and find where the yellow wire enters. Go to a connection point for that yellow wire and check for power there.

Thanks Neil will check it out this evening

So I was messing around on my bike I think I found the problem .I disconnected the wires going to the taillight and the headlight worked .I found all three wires a the taillight connection were cracked and probably touching. I love wiring

A short in the wiring makes sense. Fully potted LEDs lights are a good thing compared to old filament type tail light bulbs. I've seen many a bulb socket full of water and corroded.

Ya the taillight is led so just a matter of fixing up the wires and I should be good to go
