RE: Fuse on starting battery

A second problem is many alternator outputs simply go to the starter terminal.

Its close , and the wiring is always ample to handle the alt output.

Should a fuse disconect an operating alternator its usually diode time.

Have the press and spare diodes aboard?


A good rotary switch and proper wiring solves this.

There is (on a good rotary switch) an alternator field power terminal.

It breaks the alt field before disconnecting the selected batt.

Connects the batt , then powers the alt , when selecting a batt.

GREAT INSURANCE , if your alt is hooked to the starter.

IF someone were to go to the trouble of rewiring to install a field disconnect switch , I would add a manual switch in the event of V reg failure, with the chance of over voltage charging, boiling battsets.
