I used my PB Blaze this morning for the first time with a Sigma wireless speedo and the speedo craps out when the light is on. It just freezes - no mileage accumulates, and the speed eventually goes to 0. When I shut the light off the speedo comes on immediately.
I tried moving the transmitter farther up the fork and the light further out on the bars - no joy.
Anybody seen/solved this problem?
