Cripple rooster, you would still have the alternator, and you can switch it back on with one press of a button, so you're not relying on an external source of power exclusively. The way I plan to 'bypass' my alternator would be by using a second battery which keeps the starter battery charged in the same way that the alternator normally would, so the starter battery would remain 100% fully charged all the time...

...but then each of us has their limits. I, for example, would not want to do anything to my car which makes it look odd in any way. No fish tails or boat tails for me!
