Nissan Pathfinder 3.0 1988 - 420 ohm resistor coming off a second starter solenoid terminal #Archived Message

I had an Email from a friend in the USA re this vehicle. He has used Autodat and MOD and I have used all my wiring diagram books and CDROMs and can't find this resistor shown.
On the starter solenoid, there are two small terminals. One is from the ign. switch crank (pin 50)as normal and the other one goes to this resistor (420 ohm). The resistor ciruit is live on crank with the supply coming FROM the solenoid. Both these wires are in a standard harness coming from the starter and going to a standard Nissan Harness connector.
I've had some "suggestions????" that its used in the ignition circuit to "boost" voltage to the coil on crank and others that suggest its the "ballast resistor" ???
Have discarded both as its 420 ohm and only powered on "crank". This equates, at 10V crank, to approx. 0.026 amps which would cause a voltage after the resitor of 1.6V
I have contacted Nissan Australia and they haven't got back to me yet so I thought I'd throw it up the lads!!
I know supersitions are nice but I am really looking for the actual reason this resistor is there.
I have drawn up a circuit re the starter motor but I am not sure how to upload it.
