SWB 90 2.5TD- Dodgy Electrics

hello All, first posting here so hopefully I won't make any clamatous
errors and get flamed to death.

Im on the prowl for ideas really. For some reason my 1989 90 has
developed 2 odd faults.

Firstly when I turn off the ignition the engine keeps running. Know I
know why the previous owner fitted a kill switch to the fuel pump
solenoid. This seems to stay live even when the key is removed. I have
tried fitting a new ignition switch but this has not helped. I have a
feeling it may be to do with the starter relay itself or the wiring to
the started reley. Has anyone ever had a similar problem, if so how did
you resolve it. Also does anyone know whether needing the kill switch
to stop the engine constitutes a failure as far as the MOT is
concerned.

Secondly, deffo MOT failure this, I seem to have a cross connection
between my right indicator and my sidelights. When I turn on my right
indicator my sidelights (both sides) flash too; and when I turn on the
sidelights the right indicators, front, side and back come on
permanetly.
I've tried tracing cables but I cant figure this one. Where are the key
earth points for these circuits, could a duff relay cause this? Anyone
got a good fault finding sequence I can try.

heyyylllpppp! Failing any advice does anyone know a good auto
electrician specialising in Landys near Staines Middx

TIA, Paul

Sounds nastily bodged. My only experience with diesels is with the
300TDi, this has a stop solenoid in the engine bay that unblocks the
fuel line when the ignition is turned on, and the fuel pump also gets
powered up at the same time. When the ignition is cut, the stop
solenoid blocks the fuel line and the pump turns off. Sounds like
someone had problems with yours and bodged it.

This sounds like a dodgy earth. A bulb is a piece of wire that is
connected between live and earth, if you have no earth connection then
the current through a lamp finds a working earth by passing through
the other bulbs, which causes them to light, normally a little dimly.
What happens is that lamps that operate independently from each other
will have independent live connections, but those physically close to
each other will have their earth connectors connected together. Then
this is connected to the chassis. It's this chassis connection that
rots and causes symptoms like you describe as the current flows
through the other lamps to try and find a return path.

Hunt for the chassis connections used by those lamps, undo them, clean
them, and try again.

Good luck with it all!

Don't know about the MOT (though I don't recall anything about turing
the engine off at all!). Has someone fitted a radio at some stage?
I'm asking as your stop solenoid has got a permenent feed so
perhaps someones though "oh I'll stick that wire on there" type
of thing.

Almost certainly a bad earth, follow the other repliers advice. Quite
likey someone has mixed up earth and 12V somewhere forgetting a
common earth mixed up with 12V doesn't always give the desired effect.

welcome, come on in and pull up a comfy chair. I'd put the kettle on but
someone borrowed it to fill their washer.

No idea on your diesel issue - I had a large-ish (3.5Ton?) van out on
rental that wouldn't die. Chap at the yard said to stall it - mentioned
something about valve-lifters I think.

As for the electrics, like Ian said - I'd bet a pound to a penny that
fixing a decent earth connection will solve it.
