Two Prong Flasher Auto Cancel Mod

[bikerphil]

can someone with a known good OEM flasher and canceller check what the voltage is on the yellow/green wire at the plug from the cancel unit when you turn on the ignition with the turn signal switch already in the right or left position (signals on when you turned off the bike, signals should either not come on or flash just once (shouldn't come on at all with the OEM flasher)) and let me know what you get?

Cy, I get 11.46 volts at yel/grn.

Ok, just tried it again, this time I get 3.51V

Phil, try unplugging the flasher; you may be getting backfeed from the capacitor or the other coil....

Flasher unplugged, 10.41V

I need to see what it gets with the flasher plugged in, cause it's with a load that's important. It may have been initially needing to kick in, but based on what I'm seeing with a 30ma relay coil load on the cancel unit, having a 160ma flasher load would put the voltage about where you report on the lower reading, so that says I need to add a transistor to the circuit to provide the 12v it wants reliably.

Ok, I checked voltage one more time this morning before putting the 79SF back together, 3.58 volts. Later today I'll check the 79F's voltage and report back.

Ok, the voltage at yel/grn on my 79F is 3.22 volts. The battery on this bike is a little weaker than on the other bike.
