If you run an underhood bypass cable, fuse or breaker it. BUT THAT DOES NOT mean you don't have to fix the bulkhead, and then bolt the old ammeter wires together. the old big RED and BLACK still need good bulkhead terminals as then are not paralled infeeds into the pass compartment.
Some have run a wire from the alternator to the starter relay battery terminal. Is this the same results basically as running it to the battery itself?
