Getting there. Just removed the power connector to the stop valve. I expected 2 terminals but there are 3. One marked +, the others 1 & 2. Before I connect 24v would you agree that + = positive and one of the other 2 or both, negative?

UPDATE - Progress I think - removed the magnet from the fuel valve and connected 24v to the terminal marked + and negative to each of the other terminals in turn on the magnet - screwdriver inside magnet and zero result. I think this means that the magnet (solenoid) is defective. I will check this again by reconnecting the magnet to the cable from the ignition and get someone to turn the key to stop and see if anything happens. A passing engineer suggested swopping the magnets over from the other engine to see what happens. This would at least confirm or not that the magnet is my problem. Sort of suprising as what can go wrong with a magnet? I'll let you all know what occurs.

An electro-magnet with a broken wire in its coil is no surprise at all.

List price for a replacement £260 - shocking - literally. I'll look around carefully if it turns out I need one.

Paul, I've swopped the electro magnet from the port engine to test if that was at fault. It turns out that the valve must be the issue as you suggested initially. Before I do anything stupid, when I unbolt the valve should I be watching out for springs or gaskets and will fuel start flowing out? I can turn off the supply and perhaps put something under to catch any parts that jump out. Can I reuse any gaskets? Thanks. Nearly there.

Paul - an update - I had some help today and tested the connector to the magnet - +ve and -ve both OK. Since I had already tried the functioning magnet from the other engine here, I deduce that the problem must be the valve. I removed it and took a look (photo). It was a little hard to push the inner tube but I did and flushed some bits out. Now soaking in brake fluid until tomorrow. In it's "relaxed" state I can see small openings around the central

FINAL UPDATE - thanks to VolvoPaul for the advice - first suggestion and the simplest was the solution. I removed the stop valve, soaked in clutch cleaner overnight and it worked perfectly. There was clearly some residue stuck around the valve which flushed off. So all OK now.

Great news - I love it when a cheap fix is achieved and well done for posting pictures, I am sure it will help others in the future...!

I know this is an old thread but just a word of thanks after finding it with the search. Soaked my valve overnight in brake clean and the shutdown works like a charm now. Big relief seeing the part is nearly $700
