Re: Electrical gremlin in dash

:(
Ah well, more money down the drain.
On the bright side it was only 2 quid for 5 voltage regulators. I can always sell them on ebay. :ok
.......... still no joy with the gauge.

Re: Electrical gremlin in dash

Battery's fine. It's not when all the electric things are switched on it's when any one or more of of these come on sidelights; headlights; indicators; hazard warning lights; brakelights; heater fan; screen wash; wipers. :cry: but not when the glow plugs are on (wired separately, not through the mai...

Re: Electrical gremlin in dash

Thanks, I'll track down a voltage regulator before I bin the gauge. :ok Not actually checked with a meter, but every other piece of electrical equipment seems to perform in a stable manner, all lights maintain their customary brilliance, and there are no odd noises............... :rofl And that's no...

Re: Electrical gremlin in dash

Why not just put a voltage regulator to the the illumination on the guage and see if that cures it? A LM7812 will keep it stable. The fault persists even without the illumination, but I'll try anything at this stage. How about a voltage regulator on all 3 leads: power; sensor; illumination? 3 July ...

Re: Electrical gremlin in dash

Yesterday I wired the eff in gauge direct from the battery, bypassing ALL the dashboard wiring and electrical influences (you would think!) and still the gauge drops to zero when I switch on any one of these: sidelights; headlights; indicators; hazard warning lights; brakelights; heater fan; screen ...

Re: Electrical gremlin in dash

"With the sensor wire soldered or Scotch-locked into the yellow lead" which is it? the sensor wire goes straight to the display, not cutting into the yellow illumination wire surely? :oops Sorry Hacksawbob, it was the power supply and the illumination that were connected. Sensor is on its...

Re: Electrical gremlin in dash

And indicators now. :shock:
Is there a voltage regulator I should come through maybe?
It's a great thing this forum. Never had so many bright ideas. :D

Re: Electrical gremlin in dash

An update on this annoying gremlin.........
I have noticed that the reading drops when I apply the brakes as well. It's not inertia or momentum: it happens when stationary and before moving off at all.
Who invented electricity anyway........?
Grrrr........

Re: Electrical gremlin in dash

Gauge has 4 leads: red power supply (taken from R side of the back of the fusebox); black earth (connected to one of the fusebox assembly mounting screws); yellow illumination (from another connector behind the fusebox); green sensor. With the sensor wire soldered or Scotch-locked into the yellow le...

Electrical gremlin in dash

I killed a diesel engine last year. To avoid doing it again this year, I have fitted an electronic oil pressure gauge. It's one with a load of red LEDs around the perimeter that light up and give a pleasantly reassuring impression that all is well. So far so good.... Till I turn on the sidelights an...
