Alternator Wiring Upgrade

I build whole electrical systems for cars at a restoration shop and I can say with electric Fans and fuel pumps it is very wise indeed to re work your electrical system. I usually use at least a 10 gauge wire for my alternators. If the load is heavy I might even use 8 gauge. I also upgrade Battery Cables. I really like to use 1/0 welding cable. It's more flexible and heat resistant.

Hope this helps
