Michael,

What size alternator does your car have on it now ? I don't have a heater but am running twin fans and an electric fuel pump and I have a 100 amp alternator and my voltage never dips at all. My battery is also mounted in the back so I have the extra length to run the battery cables. I was going to use a 65 amp alternator but one of the guys here told me I would be pushing it with my setup even though it would most likely stand up to it for a while.
