Subject: AeroElectric-List: WAS: Sizing a B-lead ANL now "master fuse" on the battery
box.

Sort of related query.

A J3 Cub is being converted to accommodate an 0-200 engine with electric
start.
The battery box is behind the baggage compartment, and for the sake of
simplicity, there is no master solenoid back there, so there is a hot #4
wire all the way top the firewall.

The only electrical load is the radio and intercom, for which there is a
switch and circuit breaker.

I want to add a fuse of some kind at the battery box to prevent a "shower
of sparks" welding event if there is an incident which causes the steel
bits to cut into the hot battery cable.

What is the likely current draw on a typical lightweight starter for an
0-200, and what is the suggested "fuse " mechanism?
