Strange coincidence.....

On friday last i had the same fault on my car.

Pulled up at home then later tried to start....nowt, dead.

After a few electrical checks it was the solenoid trigger wire at the starter motor.....poor connection.

Cleaned it up and immediate start.

Nothing to lose by pulling off the wire and refitting.

If you are unsure which wire its the thin one, generally with a spade connector, and between the two heavy cables.

There is no power from the cabal john had meter on it will turn over with a jumper cabal from battery

Same on my Ducato last week. Same fault, exciter wire damaged internally at the solenoid. No voltage showing on the solenoid but started after a wiggle. Conductors inside cable broken up.

Since 2009 with motorhomes several caravans then tents before that.
Same thing happened to a car of ours All lights on dash worked, as did electric windows. When they checked the solenoid , it was ok. Turns out it was the earth strap in the end.

Had a similar thing on the old G Reg. Someone on here (think it was ppj) said check the Earth Wire from the block to the Chassis

Bill checked for voltage at the starter solenoid using a meter so a bad/non existant earth would make no difference.

When key tuned no power to wire ?

I tested the voltage at the solenoid connection, nothing. I Bent the cable gently and there was a length of cable about 10mm from the connection where the cable bent easier due to the copper conductors having snapped within the sheaf. After that it started as I had made the conductors touch again by bending it.

I cut off the end 50mm of cable and reconnected with a new terminal crimped on. That'll do for now but I shall replace that whole length of cable between loom and solenoid.

Try starting it by putting a direct feed to the solenoid exciter terminal. If that starts it you can test the output from the ignition switch. If it turns out to be the ignition switch you have the choice of either replacement, or bypass the ignition switch starter terminals with a fused lead via a push button on the dash. Assuming the vehicle is reasonably modern it will only start with the key in the ignition due to the immobiliser.

I am sure I don't need to say this but make sure the van is not in gear when testing things(y)

No voltage at spade AND won't turn over when direct feed suggests bad earth. When you tested the feed to the solenoid did you measure the voltage between the spade and the engine block, or the spade and the chassis?

In post #5 Bill says it WILL turn over if a jump lead is connected from battery to starter motor battery cable which eliminates a poor engine/chassis/starter earth.

He also said in post #9 there is no voltage at the trigger/exciter wire....presumably when the key is turned.

This all points to a faulty switch or a break in the exciter wire

Losing the plot Bill....?

At post #9 you said there was nothing at the trigger wire yet in post #19 you Insinuated you hadnt checked the voltage at the trigger wire....

Im confused !!!

Have you twatted the motor with a hammer.....

Sometimes the brushs can stick or possibly a dry/dirty segment on the commutator.

A belt with a hammer can sometimes sort it.

sorry for the confusion @papajohn the meter had its plugs in the wrong place some young chap ben messing with it so it was sowing 0 volts now when on exciter weir showing 12.80 volts
so that's taken a few things out of equation
