    Question Jump Started Car, P1900 damage?

    Something is up with my power. Recently, I've had to jump my car. Yesterday, I just had it sitting with the doors open (I don't think it matters, lights were off) and I couldn't crank it.

    This morning, it was dead again. The Mac was sitting there sleeping however. So I jumped it with a 75A plug-in-to-the-wall starter. After that, the mac mini does not turn on in the car. I can turn it on inside with its original power cord. When I use the P1900's cord or use a small coleman inverter, no good.

    Its worked fine for a week. I went to Advance Auto Parts to get a battery diag and it checked out. Listed as "good".

    What's weird is that the Xenarc still gets power just fine. I don't know if the iSense is sending the signal or not. I'm not sure whether I damaged my p1900 or my truck needs to run two batteries.
    Right now, running off of one Interstate Battery: 6 KC Aux Off-Road Lights (I use 2 as the aux brights), CB Radio is sometimes on (off of a 15A fuse) and the P1900 to the Mac Mini and Xenarc 700TSV.

    Has any one had problems with Jumping their battery with their CarNetix?
    Or do you think my CarNetix is sensing I don't have enough power.
    I'm definitely unsure and considering doing the dual battery setup. I could use the extra volts if I forget to turn off the map light when offroading!

    Time to break out the old voltmeter, and see how much voltage you're getting to the P1900. Are there any fuses that may have gone? You didn't happen to short any connections with the jumper cables did you?

    thank you so much for the response.
    However, its working fine now, actually. Runs just fine.

    I took out both connectors and let it reset I guess. The old Router Reset technique. Actually worked. I'm believe that the P1900 was confusing things. Its all good now, thanks!

    Sweet. Good to hear! Sometimes just leaving things alone, or unplugging them does fix issues with them. What a relief that is when it works!

    I know this late but it will help someone else.
    Just unplug to battery feed and hook back up and it will work again.

    Yeah, that's exactly what I found out. Now I have a power switch on that line so I can have no power being drained when the car is off or being sent to the unit when I'm jumping it. That way, I don't have to worry about breaking the connector.
