Technical Power steering gone but light not on dash

Post17 ??

Put the multimeter on volts one probe on the top of the battery negative terminal, the other on the engine block, have someone crank the engine

Should be under 0.5V

 

[garryrussell]

Ok

 

[garryrussell]

With the possative lead on the negative terminal and the other on the rocker cover it’s fluctuating between .6 and .9

With leads reversed its higher

Faulty earth strap under the battery going from the chassis to the engine block

I’ll change it tommorow . I did hold a wire on negative and other end on the block other day but no joy

A perfect earth it should top out at under 0.2V that's straight as cranking starts then drops

I don't overly worry if it's under 0.5V, just know it going to need sorting soon

Worth looking at first could just be dirt contacts or loose bolt

Cheers I’ll let you know tommorow

Earth replaced and still same. No lights on dash but power steering still not working

What's the voltage measure now

Put the multimeter on volts one probe on the top of the battery negative terminal, the other on the engine block, have someone crank the engine

 

[koalar]

Does the light come on with ignition on, then go out and stay out

Or does the light not come on at all

 

[koalar]

If you lift both wheels, does the steering turn lock to lock smoothly

 

[koalar]

Any update, are we getting anywher

I’ve checked all fuses under bonnet next to battery and done the test you recommended.it fluctuates up then settles at near zero. Still no steering light on dash. I have noticed if it’s running and I put foot on brake for around 8 seconds as I lift foot off the engine idle raise fora second

 

[koalar]

Still no steering light on dash

Nothing at ignition on

fluctuates up then

How much during cranking, still around a volt

No it’s a digital meter and settles prob more than fluctuates

 

[koalar]

Post a video of the dash, keep it as short as possible, let's see exactly the behaviour of all the other lights on the dash, immobilizer, charge oil engine check, at ignition on, cranking, and running

No it’s a digital meter and settles prob more than fluctuates

Unplug the injector harness or similar to stop it firing, crank sensor or ECU plug also works

Crank for about 5 seconds

And give us a voltage reading so we can move forwards

Ok disconnected and with leads negative to negative and positive on engine it reads 0.34 and swap lead an it’s 0.0

Shouldn't make any difference which way round the leads are, just the measurements will either be positive or negative, probably 0V is poor contact

0.34v is a acceptable
