reference fuse size.

I measured a solenoid coil I have here, similar to bondy's original one & got 4.1 Ohms .
Ohms law tells us I = V/R therefore I = 12.6V/4.1 Ohms gives 3 Amps.

Auto cable:
3mm 10 Amps Light Loads, Headlights, Stereo/UHF
4mm 15 Amps Driving lights, Compressor type fridges
5mm 25 Amps Power feed for other circuits

This formula ensures the fuse will blow before the cable melts.
IB < IN < 0.9 x IZ
Load Amps < Fuse size < 0.9 x 10 (3mm auto wire)
3 < 5 < 9

The figures above satisfy the formula (so, a 5A fuse should not blow while starting the engine)
A 10 A fuse would not be suitable, as the cables capacity will be exceeded to make a 10A fuse blow.
These are my best figures for using 3mm. 3mm automotive contains 16 x 0.3mm conductors or approximately 1.13mm�.

Some other diagrams that may help.
Your magnto kill wire should be going to the stop switch in the diagrams below.
