I tested again when turn engine on but not start, multiple switch turn on the
- Low position: only black terminal have battery power, and the other purple, yellow, gray and dark green all no voltage.
- High position: also the same result as above, only black terminal have battery voltage and other four terminal no power.
*** That means ground circuit is lack of power.
How to check ground circuit before test multiple switch? Thanks for your detail instruction.
When engine turned off state, when put multiple-switch put on
1. Low position: Yellow 10.4 V, Black 12.14 V, Pump motor: Dark Green 10.39 V, Gray 1.300 V;
2. High position: have same results as Low position when not engine turned on.
So, the ground circuit all no power.
