[C320-list] Fuses at the 3rd Battery

[Jeff Hare]

Jon's right, but you don't want fuses in the circuit between the battery and
the starter.  They wouldn't function as intended.

Starter can draw more current than that wire can sustain except for short
engine starting durations.  Feel it after some extended cranking and it'll
be warm.  That happens in just a minute of cranking.  So to keep the fuse
from blowing in normal conditions, you'd need a fuse that allows more than
the starter should draw.  A short that permitted that kind of current flow
might not pop the fuse, but could still damage and overheat the wire.  Can't
win there.  There's no fuse between your car battery and the starter either.
Same circuit.

Bruce,

All batteries should be fused...you can use the same as you did for your
house bank...

Regards,

Jon

C320 #1084 has 40 Amp fuses, 7" from the 2x4D batteries.........as now
installed by Catalina.

Question:
should I have installed a FUSE, 7" from my new 80amp Starting
Battery?????????
Should it be 40 Amp?

I followed the 3rd Starting Battery Tech notes (as on the C320IA site), but
I do not recall installing a Fuse at the Battery.
I am a bit worried. We will be back on board, this afternoon.

thanks in anticipation.
