My son and I installed the steering wheel, stator tube, and control head today and after getting it in we hooked up the wiring, reconnected the battery, and tested the horns (worked fine), and the left and right turn signals (oops). We were using an LED style shop test light and it lit properly when I activated the left or right turn signal on the control panel but it didn't blink as we expected. Hmmmm.... we then buzzed out all the connections to the turn signal flasher unit - all hooked up properly. It just refused to blink. I then tested out the wiring to my turn signal indicator on the dash as well as the bulb - both fine (this is a brand new Moss wiring harness we are using).
Oh well - we guessed we had a bad flasher unit. Beats having to buy a radiator...but wait!
After thinking a minute about that LED test light, I suspected that the flasher unit might need to see some resistance in the circuit, so I hauled out one of the actual front turn signal assemblies and we jury rigged it up instead of using the test light - viola! It blinks! Seems that the flasher unit needs to "see" the resistance provided by the bulb filament in order to actually blink. At least that's my theory. It blinked rather faster than I expected but I just bet that when we get both front and rear lights installed that it will function correctly.
In any case, just wanted to post this in case someone else might be doing a full resto and tried testing their turn signals without actually having them installed on the car.
