Hopefully this will be the last of my electrical gremlins for a while. For as long as I can remember whenever I have the heater blower running on full blast, my voltage drops noticably, by about a volt. I'm curious if this is normal or if I possibly have a bad ground/short somewhere. I find it hard to beleive that the blower motor draws that much current. Having my headlight on, running both windows and the rear window doesn't even drop it that much.
