[Mgs] Cooling issue, revisited

[Gosling, Richard]

I'd guess your voltage stabiliser is dead.  This little box of tricks
hangs around the back of your speedo, and converts the rather variable
12-14.5V at the battery to a steady 10V (or more specifically, switches
back and forth between battery voltage and 0V to give an average of
10V).  This prevents the temperature and fuel gauges rising every time
the voltage rises due to an increase in engine revs.

Is your fuel gauge reading high, as far as you can tell?  If it is, it's
definitely the stabiliser.

It is hard to test using a digital multimeter, because of the way it
works - the digital meter gives you an instantaneous reading, so will
jump around between 0V and 12-14V (unless it's an advanced one with an
averaging device).  An old analogue multimeter will show more
effectively.
