I'm in the process of doing the electronics on my 450k5 cafe build. I wanted to test the old handlebar control switches prior to wiring them in because they look a littlle suspect. I was able to test the switches for the turn signals, kill switch and headlight (on,off,hi-lo) and brake lever button switch for the front shoe type brake. (cl hub)
I was not able to figure out a way to test the horn and starter.
After some thought, I figure it might be possible to probe the test light into the back of the botton switches and complete a circuit by creating a loop that breaks at the switch. Tight area and delicate switches.
Any known method for the single wire button switches?

Set meter to read continuity...... one probe to wire, one to ground...pushing button closes the circuit....

So my test light is'nt high tech enough.
I'll take them to work and use the meter on them. Thanks for the help. I try not to use the spark or heat method of wiring (any more) :lol:

A light would be ok to indicate continuity, what it won't tell you is the resistance. If its high, you can easlilly lose voltage on a low voltage (such as 12v) supply, but still show a flow by the bulb lighting up.
I would use either a digital meter on continuity or even check on resistance. Then I am lucky enough to have a Fluke meter.
