Tried a new solenoid coil when the problem started, made no difference. Wiring has not been altered since installation this is what is bugging me why it won't work, will get a meter and see what that says. Thanks.

Tried wrapping brown wire around king lead, no difference. One thing I have noticed with the ignition on engine not running if I remove brown wire from negative terminal and then touch the terminal I can here the solenoid (fuel cut off) opening with a solid clunk. If I try it with the engine running ...

Ok thanks for that, will have a look in the next week or so, if I get it to work I will reply.
Thanks again for the help!

Have got two change over switches, the original and a new one. The only difference between them is the LEDs are slightly different, does not matter which one i use it won't change to gas.
Will try wrapping brown wire around king lead, will let you know what happens.
Many thanks for your help on this ...

Stem is new, think brown wire goes to negative post on coil

I have an omvl r90e vapourizer on my military land rover 101 forward control. The problem is when changing to gas the blue solenoid just after the filter housing (shutt off) is not activating and not letting gas into the vapourizer.
The black solenoid on the vapourizer is clicking ok, I have check ...

Did take valve assembleys off, no gunk inside springs seemed ok, filter all ok, have not yet tested with ammeter, Gas is getting as far as filter because if i carefully slack filter cover its pressurised. When its on gas its fine, thanks for the info, will put meter on it and see what readings I get.

For a while now my OMVL single point system has been playing up. Some mornings it will change to gas some times it wont. I have changed both solenoids, either side of the filter housing. Sometimes when changing from petrol to gas (carb set up not efi) and after the petrol has been used up if i turn ...

Took solenoids off, on the inside of one where it slides over the brass part there was a bit of plastic that had folded itself on the inside of the solenoid, no idea how that got there. Took it off and now running ok, must have been giving a bad contact. Thanks for the pointers.

Yes I understand the three stages on the switch, it was running fine for ages.

I have a OMVL R90/E system on my 3.5 v8 land rover. Getting it to run on gas is not happening. When pressing the change over switch, once the petrol has been used it stops as no gas is getting through. When I slacken of slowly the LPG supply pipe there is gas in it so it's getting to the vapouriser ...
