Rain and the alternator
I drove home from a car show in the rain this past weekend and noticed that the volt gauge was showing variations which usually aren't there. I had the lights on and my one wiper going but turning the wiper motor off didn't seem to matter. The guage usually shows about thirteen volts cruising but in this case was jumping to fourteen and then below thirteen but going back to it's normal reading. It occured to me that as my engine is pretty exposed the alternator was getting wet. Is this a problem and if so what should I do about it? I am not using a full hood and don't really want to.
