Thanks for working with me on this. I do not understand what you are saying to me.

I am measuring a 2 volt drop, I think. Again, my electronics is weak. I don't know if I am properly measuring anything but I am very clear about what I did. I do not know if what I did makes sense. But to me it shows what is going to the Voltage Regulator.

I put a the red prob on the RIGHT side of the Resistor/ballast contact and the black prob on the battery (-) and got a little over 6V.

I then put the red probe on the LEFT side of the Resistor/ballast contact and the black prob on the battery (-) and got a little under 4V.

If there is something else to check, please let me know. Should I probe at the coil?

I did notice a 1/2 volt drop that I did not expect. I think I am losing a 1/2 through the key/ignition switch. I probed a little ove 6V when I hit the HOT terminal at the bottom of the ballast/resistor (this is the 3rd terminal on the bottom of the ballast resistor which is always hot and not keyed). When I probed the the new hot terminal that I moved off of the right terminal of the ballast resistor (which I had to move because we were changing this to go to ground) which is keyed, I lost about 1/2 a volt.

I believe with the 6 volt EI, every 1/2 volt is important. Not sure.

Any thoughts as to what I should check? Is a 2 volt drop caused by the resistor too much? Will the EI work with 4 volts going to it?
