Technically you're right, however, what makes them blink is the total amount of Wattage used in the circuit. I just thought that it would be easier to at least see if the voltage is the same with both switch positions. If there is a voltage drop on one side, then the current flow is reduced and the flasher won't heat up and open to make them blink. In any event, you seem to have a differance between the Ing and Acces. sides of the switch. And since you did not mention any other problem, it seems that the trouble is in the wiring.

I'm going to check the voltage at the bulbs now, but I would think that the flasher operates on amperage, rather than voltage. But I'm not an electrician. I'll go over now and see what the voltage is on both sides at all bulbs. Mike P.S. As I mentioned, I'm not an electrician, but it seems like a gnawed wire could reduce amperage, but not voltage -- on a 12V circuit anyway...
