battery positive? shouldnt it be negative?
I was referring to the signal return test as outlined in the procedure that you cited in that link. Actually, the condition of the signal return could be inferred by going to either polarity.
Measuring between battery positive and signal return should show close to battery voltage - roughly 12V
Measuring between battery negative and signal return should show close to zero voltage.
