Install volt meter in place of ammeter wiring question

67Dart273:
I spent the afternoon surfing automotive wiring methods, and found MAD’s site as well as the diagram illustrating parallel conductors passing through bulkhead connector a continuous conductors, and amp gage removed from circuit.

I have two concerns with this method: one, parallel conductors without proper over current protection is not acceptable; two, removing the capability of disconnecting engine compartment harness from under dash harness is cumbersome if repairs to either require disconnection by running from engine compartment to factory splice continuous conductor . The instructions direct that an additional length of red & black conductor be included to facilitate repairs at the bulkhead connector.

I think if one were to undertake removing amp gage, and modifying power distribution and charging circuits as described in the MAD article, one #10 or # 8 passing through fire wall via a more electrical correct and user friendly method should be employed using a connector such as this Firewall Stud Insulator.

I must say their remote voltage sensing method of connecting voltage regulator to a common power distribution point with little or no voltage drop warrants additional consideration. Eliminating five or six points of voltage drops in our Chrysler voltage regulator circuit as current passes in and out of bulkhead connector would be helpful in maintaining proper voltage levels.

I need to think these harness redesigns over a little more before deciding what to do if anything.
