Bei meine inno 1001 74 ( 136o engine ) borletti instrument
I check the cabel and the conecction, all ok,.
But once in a while the needles go straight to the right into the red section( engine not warm)
then I tip with with my Thumb ore something on the the instrument and it goes back to normal.
can you replace just the Temperatur sender from the Oval send, or do you replace the whol;e Thing. ??
