I recently installed a second battery using the Go Westy kit for my '85
Westy, but put the battery under the back seat instead of the driver seat.
I followed the directions, except for the location, and used the Westy long
wire to connect the fuse panel to the second battery, and then ran another 8
gauge wire to connect the isolator to the battery.  Everything works as
expected, except that the battery is not charging.

The alternator is fairly new.  I checked voltage on both batteries.  On the
main battery I get 12.6 engine off and 13.9 engine on.  On the second
battery I get 11.6 engine off or on.

I saw something in the archives about the refrigerator relay being too small
for a second battery.  I wonder if the distance is too much for the stock
relay and I need a different relay.  Anyone have any ideas or suggestions?
