[QUOTE="Buck, post: 8744349, member: 591582"] I'm not on anyone's side here. You can have voltage spikes without current increase. That's why you can fry a car computer with an alt that loses voltage control, because it'll never blow the fuse from too much current. That's what I experienced with my 3 different alts that I had on my Explorer. I've had an alt charge at like 17v, EVERYTHING IN THE VEHICLE SHUT OFF except for my motor. My entire dash stopped working. Thank God I had my Stinger voltage meter. I stopped in the middle of a very busy street in the middle of the road to unplug my alt and I immediately went back to the shop I was affiliated with to fix the issue. High voltage doesn't mean high current. That's why your 120v little house wires are so tiny but your 12v wire is 0 gauge. Wattage = Voltage * Amperage (in short, there's more factors) More voltage means more wattage, not more amperage. If you run higher voltage, you actually need less amperage to make the same wattage.
