I just looked at some old build sheets on alternator size and SF recommends nothing bigger than 65 amps. Anything bigger may fry the wires and amp meter if there is a problem.

Their recommendation is another 10ga wire run along the current wire and change the amp meter to a voltmeter. With that said my 150 amp is stupid over kill, it was recommended by Prestige. I don’t really want to rip the dash out to change the amp gage to a volt gage. Plus, why not use an inline fuse to protect the wires, hmm

Any idea if SF upgraded their wire size to allow larger alternators without frying the system in case of a problem? Also any idea what the max size alternator the Smith amp gage can handle.

If the wiring hasn’t been updated what size alternator is best to run everything?

Heat fan: 5amps
Rad fan: 24 amps?
Lights: 6 amps
Ingnition: 4amps
Total 40 amps sound about right?

Thanks
