A couple of years ago purchased a 'circuit breaker' thru Green's, the box notes it is reportedly a Ford Service Part #: C5TZ14526J : made by Metal & Control Inc. in Mass. I am not knowledgeable when it comes to automotive electrical circuitry so for years I ran a 40-50 amp breaker purchased thru local parts store w/out any problem thinking if the ALT circuit was going to trip rather it be at a lower amp value, goes to show what I know. Had I come across Crop Duster's set-up I would have gone that route.

If you guys want to run the 70 AMP Circuit Breaker that's fine - realize it is not original and has nothing to do with a restoration.
Since my truck along with most others on here is a modified. I'll go with a little circuit protection instead of having my Alternator gauge be the only fuse in that circuit. The electrical system in these trucks is primitive at best. You might notice that a few years down the road around 69 I think Ford finally started putting Fuse Links in the system to protect some of the equipment. I'm not a big fan of Fuse Links but they work.
