Its at http://home.btconnect.com/djbeer/id32.html

If the starter motor is turning at all thats probably a different problem. The problem I and many others have had is it being totally dead when you try to fire up when the engine is hot and has been standing for a few minutes e.g. when at a petrol station. This mod sorted mine out completely though.

It is simply introducing a relay into the starter circuit. Mr Beer seems to think it is something to do with resistance of wires when it is hot. I believe it is more to do with internal resistance in the starter solenoid & more significantly overloading the immobiliser circuit (relay for this is undoubtedly advantageous!), which of the 2 is more affected by heat/fatigue I can only guess (seem to be more alarm problems than starter motor failures tho wink ).

Nope, not me ! I have only said a 12-13 amp circuit should not have a 6 amp drop through the wiring up to the footwell, where it joins Range Rover wiring to the solenoid. A hot solenoid may be "sticky" and there is not enough voltage to pull it in. So putting a relay back into the circuit( it was there but was bypassed) means there is not the 6 amp drop.

I would like to add to the many previous comments of gratitude for David Beer. He invented a solution to this very embarrasing and inconvenient problem, helps you with advice and sells it to you efficiently and very cheaply. Thanks.

I have just bought the mod, for the price it seems very well made, and looks simple to fit. With all this rain not got round to doing it yet. Maybe this weekend. Mr beer is very helpful too

You need an earth braid from the battery neg to the engine. You can enlarge the battery breather hole and poke it through, then onto the nearest bolt. Should do the relay mod anyway, its fine to have the hot start on a petrol forecourt, not straddled a level crossing.
