on j2-23 i have 5000 ohms and 1000 ohms when i trigger j2-24, but only with ignition off. referring to the manual i should test that with ignition ON, but then I have 1000 ohms on j2-23 and 5000 when i trigger j2-24. so with ignition on it doesnt do what it should do.

the right hand cable is connected to the battery negative, together with the big ground cable off the engine block. the lefthand cable is connected to the battery + together with the big cable from starter motor.
