Hi all

As I'm running in my rebuilt mg metro engine, I noticed today both the fuel and water gauges are not working but we're yesterday.....

Could anyone help with the diagnosis

Tks

What type of dash ? centre binicle then check the connections and feed into the voltage stabliser 12v in and 10v out on the smiths can type

Thanks Dave

I should have said yes centre binicle.
I have just checked with ignition on there seems to be no voltage at any of the terminals

With the center binnacle you may be able to probe the stabilizer terminals from the engine bay.  

 

I know you have looked before but....  With the ignition on, set your multimeter to read volts and measure between the "B" terminal of the stabilizer and earth.  The B terminal will be the one with the dark green wire on it.  If you do not find 12V on that terminal with the ignition on, look for problems along that wire and at the fuse box.

Hi Doug

I have checked all the connections associated with the stabiliser, fuse box and gauges and I have also checked between B terminal and earth and got Notting.

Is there a way of checking the cables with a muti meter?

Is there a way to check the float in the fuel tank and also the water probe in the head?

Is there another way of checking the voltage stabiliser?


I just find it strange that the two gauges are reading nil.

Thanks

Seeing both gauges "not working" points to a voltage stabilizer problem.  

Since you could not find any voltage on the stabilizer "B" terminal, that says the stabilizer is NOT getting voltage supplied to it.  Therefore, look for problems with the dark green supply wire to the stabilizer's B terminal.

 

The dark green wire on the stabilizer's B terminal should be coming from the fuse box so I would look for the other end of the wire there.

With the green wire disconnected at the stabilizer set your multimeter to measure resistance and measure the wire end-to-end (fuse box to disconnected end of the wire at the stabilizer B terminal).

If the wire shows no resistance (close to zero ohms) then the wire is OK.

If you find the wire is OK look at the fuse box, the fuses, and the back side of the fuse box as you might find corrosion there.

Tks Doug

I have measured like you said and

I have 2.5 ohms I guess this is little

I have looked at the fuses (only two) and these are fine so I will take off the fuse box and have a look behind it.

Tks again
