Hello, I have a problem with mpps, probably something wrong
by connecting it to my multiple I see in the software, the operating voltage of 12v and broken, I removed all the pins and I left only the 4-5 (mass) and 16 + 12, and I see the voltage.
by connecting it directly to the battery (charging) 4-5 at the negative and 16 to the positive pole of the software does not see the voltage.
checked cables, battery voltage, continuity?.....
I don't understand
should I maybe put the resistors?
