just replaced fuel cut off solenoid as the other one was needing a tap to engage it.....works fine now but the only problem is the enjine wont stop when you turn off the key, can only stop it if you pull the wire off the solenoid cut off valve

 

 

 

any thoughts !!!!!

sounds like uve got a crossed wire, chase the wire backwards and see if its crossed or fused any where

 

 

thats what i will do tomorrow, when it stops raining...cant understand what has happened, as it went back together alright....whip the old one out , pop new one in , put wire back on.....start up , fine stop no !!!!!

If you have a multimeter set it to DC volts and connect it between the stop solenoid wire which is usually white

or white with black stripe and a good earth such as the engine block,with the ignition switched on you should read

12 volts and with the ignition off should be zero,if you don't have a meter use a 12v bulb,with the ignition on

and connected between the solenoid feed wire and earth the bulb should light,with the switch off the bulb should

also be off. Possible causes of a feed to the solenoid when the switch is off are a faulty ignition switch or an

ignition wire has chafed against a positive feed terminal,if this has happened though you would expect other

switch fed items like the charge warning light to stay on when the key is off, atb handy

cheers andy, my mate is dropping off a multi meter, and i intend to do exactly that, if it was a chafing wire i would expect the problem to be intermitant...im hoping it isnt the barrel on the ignition, as that was new 2years ago,thye weird thing is when i switch off the enjine still runs and the charge light comes on which is what it should do, i dissconnet the white wire the enjine stops and reconnect and the white wire is no longer live........the vagories of landrover ugh....watch this space.....i think i will go and get ****** and all will become clear ... :blink:

was it a britpart ignition switch? i would think the ignition is your problem, try blowing it out with an airline and then a little wd40
