Can someone explain this so my small brain understands.
The wiring diagram for the injector harness is shown below.
K18 - Relay - Engine Control Unit
Y9.4 - Injection Valve - Cylinder 4
When I tested the voltage across the battery terminals and points A and B on the injector plug I got the following results:
My question is why am I getting 12V across the +ve battery terminal and Point A? Shouldnt that be 0V or very close to 0V?
