306 service indicator

I suspect something is very wrong with my 306's service indicator. it
does not come on with the first turn of the ignition. But if I turn
the lights on with the ignition off the spanner lights up but with the
trip and odometer mileage.

Any ideas?

It's def not working right. It's a diesel and at no setting of the key
switch does it come on with the miles to go for next service. There is
a wire trapped where it ought not to be - I can see it round the
steering wheel surround IIRC it is orange - one of these days I might
get round to having a look at it. Until then it will be a matter of
writing down the milage on a bit of paper like I did with my Mk I to
figure out when to service the beast.
