Thank you both! I will attempt to locate the resistor which is a "suspect". I do see something which looks like a smalll temrinal block on the fender with green/yellow wires. If I can, with this aid of the diagram, verify that these are they, then maybe I can bypass and short 12 volts, across them to eliminate the switch as an issue. If the switch can supply the 12v, then I guess, you're saying that the ballasts are at fault.
