Mark,
There are those that will say that is a NO NO but I have switched from 1 to 2 to both for the past 10 years without frying my alt. You are correct that if you switch to off it will fry the diodes. As long as your switch is a "make before break" you won't be interupting your alternator output. Some switches may break contact from one contact before they make contact on the next post, obviously mine makes contact before it breaks the contact it is leaving.
clear as mud right.
all right guys, give me hell.
Steve
