I bought one, and after spending several hours adapting it to fit into my cylinder head, I decided to test its callibration.
According to Caerbont, water now boils at 135 degrees C!
............and it is consistently out across the scale.
True 90 reads 125deg C
true 80 reads 110
true 70 reads 85
true 60 reads 75
below that it is not worth using the gauge (......or at any temp based on above!!!)
Do any of you auto electrician bods have any suggestions? |
Hi Mike,
I'm not very familiar with these gauges but a quick Google seems to suggest they need a voltage stabiliser to provide a 10 volt supply.

Maybe your stabiliser is faulty?
