Amp/bulkhead bypass question.

On my 64 I did the following, years ago:

New 10 gauge wire with fuseable link from alternator to starter relay + post.

Took black wire off alternator, shortened it, connected it to + on starter relay. Removed it from the ammeter and dead ended it.
Black wire has splice in harness that feeds dash, lights, etc.

Removed original red wire from ammeter to starter relay completely.
