Electric Temp guage
Posted: Thu Apr 09, 2009 3:33 pm
Hi All
This one of those jobs I've been putting off- better weather is re-energising me!
Having bust two of the combined oil pressure/temp guages in fairly rapid succession I decided to go the electric guage route for the temp. Because it matched the rest of the dials I went for an early Mini type guage.
It works- but the problem is that the needle takes ages to move off the bottom stop. Once it (eventually) reaches the mid-way point it stays there (it's pretty accurate too judging by comparisons I've made with the actual temp by using temp strips at various points.
It's wired thru a separate dedicated voltage stabiliser and I'm pretty sure the sender is of the correct type (but wouldn't swear to it).
Any ideas what the problem might be due to? One thing I have tried is to have a special steel adaptor made so that the sender screws into the head as far as possible (I thought the short reach of the sender might mean that it was too far out of the water flow. This improved matters but the slow initial reading is still present.
All connections are fine etc
Thanks in anticipation.
