It would seem to me that it would be easier to put away the volt meter and get a test light. turn the blinker on and start poking at the hot wires on the suspect connectors and relays until the light stops coming on. the problem should be somwhere between the last place the light came on and the place ur poking at the moment. Unless I am just completely missing something. (likely) Or have you already been there and done that?

Sev and I chatted it up and he thought to bypass the relay to check there was power to the blinkers (other continuity tests were also done).
Bypassing te relay I did get power to the indicators. Between the Fuse 11 and Pink40 there was 6.84 ohms resistance. At the switch, 0.00 both R&L. Fuse at 0.00. So, I'm taking the fairings off and going to check the wire from Fuse 11 to the relay (05), as well as check the relay itself and the wire from the relay to 40.

Ok, got the bike more or less stripped and found the Indicator Flasher (#05).
Results of continuity test:
Wire Lb, #04 --> #05 = 4.50 ohms
Wire Pink, #05 --> #40 = 0.00 ohms
Wire Bk, #05 --> #40 = 0.00 ohms
Voltage reading across Lb --> Bk = 12.5v
I used a test light on that as well, and it shone..shined..lit up..illuminated.
No, how do I test the relay?
It has three leads: Positive (Lb), Negative (Bk) and Output (P)
On a guess, I check continuity, putting the +probe on the + (Lb terminal) and the -probe on the - (Bk terminal), that read 12.17 ohms. But if I swapped the probes to which post I touched, the reading was 4.95ohms.
