insulated terminal block
well-equipped car should have at least three of these terminal
blocks. Install one
under the hood on the firewall.
Route the heavy gauge alternator out-put wire directly to
the terminal block. And from the terminal block route a charging wire to battery POS. Connect the dash Main power-up here also, with a Fusible Link wire for short circuit protection. Connect
Other Fusible Links here for Fan Relays, Headlight Relays, Fuel
pump relays, and any other systems that need full 14 volts.
Then mount two more terminal blocks under the dash Wire battery POS directly to one, and ignition switched ON/OFF to the other.
These two under the dash are perfect for wiring gauges,
sound system, and other accessories.
