Highlander,
I would like to be there when you feed straight amps into your glow plug DB.
I'll try this one more time. Having been in electronics since I was 10 and an Electrical Engineer for too damn many years, all I was trying to get you to understand is that these are not unrelated quantities. One relates to the other. You cannot have an electrical flow without having an energy potential ie volts that is then regulated by the resistance of the load. The flow is then measured in amps. You need all three do do work.
Sorry for getting so far off the subject.

John
