Temp gauge going to 0 when car idling...
Uh oh - I was so pleased when I connected my temp gauge and it seemed to work, going up when it should and down when it should.
But as of this morning, when I'm idling it sinks back to Cold, and as soon as I move off it goes back to where it was.
I'm guessing that after all I didnt wire it up properly...
any ideas???

poor water circulation? if no water is in contact with the sensor it can give all sorts of strange readings, check water level and possibly the water pump as that might explain poor/no flow at idle speeds, otherwise regulator or even earthing to the block of the sensor

Ok heres an update...
it was working nicely. I (think *grin*) that I used the voltage regulator, at the back of the speedo.
Only recently has it started occasionally showing 0.
Now it works only intermittently (went to 0 when I was a mile from home and stayed there!)
At the same time my intermittently working indicators stopped working completely this morning - but the temp gauge was still mostly working until later this afternoon -
Don't know if the 2 are connected!
But suspect its something to do with the voltage regulator...
Maybe I should get one of those little stabiliser boxes - anyone know where?

The fact that the indicators also stopped working rules out the voltage stabiliser unit as the culprit as the indicators are not fed through it. but the regulator and indicators ARE fed from the same fused supply(the fuse with all
the dark green wires on it. The next time you get this fault then immediately
check to see if the fuel gauge, heater fan, or windscreen wipers have also
packed up. If so, then check the aformentioned fuse and all the connections
to it. It is very common for the two fuses to cease to make good contact
with their holders and they should be periodically cleaned to stop this happening.

So, no power going through it then.badfelafel wrote:Ok heres an update...

IIRC the indicators will use the same ign switched green as goes into the stabiliser, so could be a dirty contact in the fusebox, a duff fuse, or utterly unrelated.At the same time my intermittently working indicators stopped working completely this morning - but the temp gauge was still mostly working until later this afternoon -

I posted a link to Minispares who have one that looks remakably like the original Minor type, or you can get a solid state one off Ebay for around 8 quid inc p&p. The electronic ones are better, but of course unless you find someone who builds them into the original casing they do look different. Though how much that matters when they live behind the speedo is questionableBut suspect its something to do with the voltage regulator...

If you've got a voltmeter I'd double check the power into the stabiliser first, if it's OK (should be the same as the battery, or ever so slightly less), then see if there's 10v coming out. If so, then it's the wiring, gauge or sender. If there's no power or not enough into the stabiliser, suspect fusebox first, then each connection from box to stabiliser. If there's power in and no power out, chuck the stabiliser and buy a new one.

If you want a solid state regulator, you can purchase one from an electronics suplier (eg maplin) for about 50p this is a simple 3 terminal device that requires nothing more than wires soldered to it and is available in both positive and negative versions.
The guy selling them on ebay at £5 has quite a mark up!
but from the sounds of it you have a duff fuse contact, remove clean carefully and replace should fix that one.

Electrics I can do, but electronics aren't my friend - Any chance you could point me in the right direction as I need a new one soon and was going to get an Ebay one!Rob_Jennings wrote:If you want a solid state regulator, you can purchase one from an electronics suplier (eg maplin) for about 50p this is a simple 3 terminal device that requires nothing more than wires soldered to it and is available in both positive and negative versions.
Not as bad as the 50p variable resistor that gets sold for 20 odd quid as a "Performance Boost" though...The guy selling them on ebay at £5 has quite a mark up!

Went up North at the weekend (thats Scotland, not North of England!) - not in the Minor - and got back late last night. So as a late night last minute trick undid all the connectors in the fusebox, gave them a wipe, and stuck them on again. Didnt know there were so many connections in the fusebox!
Anyway, this morning both the indicators and the temp gauge worked all the way into town...
Lets see if the both work all the way home!
(PS Was glad they worked all the way in as it was very very foggy!)

Lol... theres more - temp gauge worked all the way home... indicators didnt, until the last corner that is! Then they came back *grin* just to taunt me.
Will need to do some fiddling and checking, and see why the fan isnt working while I'm at it.
I still dont like my mini fan box - but everyone says its so much better than the minor one - so not worth changing back???
