ignoring all these clever brains and their techy stuff (9.4v is low on cranking in my view), here is how I solved my clicky problem.
I wired in a fly lead to the solenoid feed on the starter and ran it up to near the battery positive. Every time I got the click, I whizzed off the bonnet and used the fly lead on the pos terminal to start the car. It never failed to crank using the direct connect fly-lead. I then did the magic relay mod and never had nasty Mr Clicky again!
