What I'd recommend is that if you have a 55a alternator, I'd go with an isolator capable of




at least a 70a. load. A 70a. alt- 100a. load etc. . Always go at least a step higher amp isolator




than what your alternator is rated for.








I have a 120a. alternator on my '77 Marquis, and I use a 150a. isolator.
