Gauge Fun!

Hi,

 

I've been trying to sort a few little niggles and on today's list was the coolant and oil temperature gauges. I've checked all the wiring for continuity and run a new length of wire to the oil temp sender in the sump as the old wire was totally naffed. I now have continuity to both the coolant and oil temp senders but I'm still not getting anything. The coolant gauge moves a little when the ignition is switched on and moves a tiny bit after the engines been idling for about ten minutes but it really is a tiny bit (I've been staring at these so long it could be my imagination...). The oil temp gauge doesn't move at all.

 

I can't yet take the car for a thrash as it's not road-worthy yet. I don't want to condemn the sender units as every time I do anything this on the car, it turns out to be the wiring... The gauges them selves seem fine as they do the full sweep when grounded.

 

Help me please as it's starting to nark me off now...

The water gauge perhaps is a duff sensor, they usually would move after 10 min idling. The oil temp however needs more like 20 min at 70mph on the motorway to show anything! So don't worry about that one.

Cheers for that Tom, really couldn't work out the oil one at all! What good is a gauge that only reads when the oil is at 3 billion degrees!?! WIll wait until she's back on the road and can test it properly before I change the water gauge sender. Thanks for the help!

As Tom said, I thought my oil temp gauge was knackered until I took the car round Cadwell. Oil temp tends to be rev related in general, i.e. the higher the revs the quicker this builds
