ignition

I did check the switch with key OFF, and turned on just headlights, (New working bulbs !).. The v did drop some 2 or 2 /5 v,.... I forget exactly/ Probably NOT good!!
Did it drop at the battery terminal?
If so, try a long slow charge. 2 amps or less if your charger has a selector, or if its automatic, you can let it do its thing overnight.
If it didn't drop at the battery, then its good enough for the testing you're doing.

I also have to wonder if my connections at the double wires at the ballast are good.
That's what we're trying to find out with the voltage drop tests. So far, that doesn't seem like they are a problem.
