Ask
questions like

I'll try and measure that again.

>How thick is the wire as the thicker it is means the more current may
flow

The wire is 1mm, therefore (relatively) low voltage/current. I've put in 
5A
in-line fuse on the circuit and that's okay.

The inverter is handling the timing of the circuits, but it is basically
duplicating the manual sequence. Once I have it working I will configure
the
actually timing more accurately. The sequence is pre-heat on, wait for 10
seconds, start on (hold for 5 seconds), start off (this is like letting go
of the key), if no voltage is found on the supply side, then turn the
pre-heat off, wait for 15 seconds and repeat. If voltage is found, then
leave the pre-heat on. To turn the genny off, break the pre-heat circuit.

>Assuming these are OK you can start to look for a relay.

I thought I had everything sussed, that when I went a got the relay.
However, things are obviously not has they appear.
