Are there are any pros/cons (recommendations) with the following options for wiring the main feed to the Relay Fuse Box?
Option 1:
Battery -> Cutoff Switch -> Bulkhead |-> Starter
_______________________Bulkhead |-> Alternator
_______________________Bulkhead |-> Relay Fuse Box -> ECU
Option 2:
Battery -> Cutoff Switch -> Bulkhead |-> Starter
_______________________Bulkhead |-> Alternator
Battery -> Cutoff Switch -> Relay Fuse Box -> ECU
i.e Option 1 has single main 12v feed to bulkhead then splits off to 3 items, where as Option 2 runs a separate feed from cutoff switch to Relay Fuse Box.
Distances:
Battery -> Cutoff Switch = 1m
Cutoff Switch -> Bulkhead = 1m
Cutoff Switch -> Relay Fuse Box = 1m
You want #1.
Remember that under normal operating conditions, the alternator is the only true power source. The battery is a net consumer, except during starting.
If you do option #2, then the length from the Alternator to the fusebox would be double, and hence double the voltage drop.
I'm assuming you'll have a pass-through post at the bulkhead. There's no harm in having 3 lugs on it.
That's a good point I hadn't actually considered, I was thinking from battery forward, but your completely right about the alternator! Thanks for the advice :)
