Correct working BMW E28 SI Board
Temp gauge indicates the correct temp.
After a signal from the startermotor (that is were I click the button) the tempgauge goes flat and transfers the signal to the SI processor.
After this, the Service Interval indicator shuts down.
This is the correct way.
This board has been revises be me, with new components and battery's
