In short (no pun intended), it's not the 100A alt install that's the problem. It's all the 50-60A wiring that is within the rest of the car, and without the proper breakers/fusable links, that could ultilmately lead to an electrical fire. If you want to live with the existing amp meter, you would need to 'spread' the load of the 100A being generated across a couple circuits. Or you could install a volt meter (which, from what I've learned, is more practical and valuable). But you still have to know what you're doing and how those extra amps will 'dance' through the existing wiring (or fry it).

Early SPF cars like the ones that Miles and I have will have wiring issues with an alt upgrade unless these things are considered. Newer SPF cars may be wired to accept a 100A alt...I'm sure a dealer could answer that one.
