Hi Gang:
I"m about to start the installation of the Z-14 system into my RV-6A. I've
absorbed and understand most of the drawing, but one thing confuses me and
that is the size of the wire running to the Starter.
| Quote: | From the starter to the starter contactor shows a 2 AWG wire, the wire from
the starter contactor to the main battery contactor is shown as a 4 AWG
|
wire.
The wire from the Cross-feed contactor to the terminal on the main battery
contactor is shown as 2 AWG. The wire running from the Aux battery to the
one side of the Cross-feed contactor is shown as a 4 AWG.
I can understand 4 AWG wire running from the two batteries to their
respective contactors, but I would think that from the point where the two
batteries join forces they should be 2 AWG wire? I don't understand why the
size of wire jumps from 4 up to 2 and then back down again to run to the
starter contactor?
Can someone educate me please?
Thanks in advance,
Terry.
