Alright Stealthee, where would the blinker module be? How to test? Wiring diagram shows a "timer", is that the same as blinker module? Also, can anyone confirm, 1) that the voltmeter should show current rise and drop with blinking? & 2) the signals are supposed to flash off when the proper power is achieved, so if there is insufficient power the light will not blink (which is why when you have a burnt out bulb the blinkers blink faster, b/c remaining lights get more power more quickly), correct? Thanks again.
