I'm working out some electrical issues on my 67 catalina 2+2. I want to replace my existing alterator and external voltage reglator with a 3-wire 10SI internally regulated alternator. I've already ordered a 10SI that's rated at 105 amps. I went to order an engine harness from M&H Wiring and the tech I talked to said my alternator at 105 amps was too much and could fry the wiring. Is this true? From all I've read here, I thought that 100 or so amps would be great to have. Also, the alternator output wire is part of the engine harness and goes into the firewall plug and elsewhere before reaching the battery, so my question is should I run another wire from the alt output directly to the battery? I know I run a wire from terminal 2 on the alt to the battery. Many thanks.
