Question Can I install a higher output alternator?
My Cobra has a Pro Design wiring harness and a 60 amp ammeter. My battery goes weak and dies after extended driving and I suspect my alternator - a 60 amp unit - is not working correctly.

Now, I have a new in box 100 amp alternator sitting in my garage. Can I bolt it on without fear of overloading my electrical system?

Even with lights on and fans running, I have never seen my ammeter read anywhere close to a 60 amp draw. Will the additional output capacity of the 100 amp unit ever come into play and if so what are the risks? Can I use it temporarily until I can import a new 60 amp unit?

BTW, I can't find a website for Pro Design to pose the question directly to them.
