Voltmeter conversion

[fintubi]

ERA has instructions and schematics for replacing the in-dash ammeter with a voltmeter.

The key step is simple: eliminating the ammeter from the connection between the load side of the master circuit breaker and the line side of Fuses #1 and #2.

There's also a recommendation to add a heavy-gauge wire between B+ and the alternator BAT terminal, especially when a high-output alternator is used. I gather the reason for this is to provide a direct path to support charging a depleted battery at higher current than the master breaker rating.

My question: if this is done, does the master breaker retain any function? The new connection to the alternator presents unfused B+ at the line side of Fuses #1 and #2 via the original orange alternator wire, effectively jumpering the feed to the same fuses via the breaker.

Thanks,
Bill
