2002 CC IQ. Pack voltage is 50.5.The solenoid is not engaging. I have checked for voltage at the solenoid on light blue wire it is 50.5. Pulled all wires off and did a continuity test on the two big post. No continuity. Ran jumper wires to the two small post from the pack solenoid did click it had continuity on the big post then. I did unplug the OBS and jumped the blue an white wire to see it that was it. Still not engaging. What do I need to test now.
