From what Lippert told me, plugging into shore power won't help much because what the convertor supplies to the batteries is just a trickle charge, and the system runs from the batteries. I thought the same thing, and still do plug it in before I level just to get every last amp and volt possible.

I had not thought of swapping plugs around. I had thought of putting a couple of switches inline with the wires so I can extend either middle jack (or both) manually when the system gets us close and faults out, but I really don't think I should have to. With the cost of these things, I should be able to unplug from the truck and just have it work. The hydraulic system just works. On one group 24 battery. No muss, no fuss.

That would be a way to see if low voltage is the issue. Plug back in with the engine running. The 12 volt from the truck to the FW is straight from the alternator to the battery and would actually be closer to 14v. That is how the Power Gear leveling on the SENECA is supposed to be operated. With the engine running and it is a hydraulic system.

I have been monitoring voltage from the control panel and it does drop to 12.2 to 12.3 volts. Before I talked to Lippert, I did not see this as a problem, because most electric components have pretty good tolerance built in. I would plug into the truck, but getting it close would be a problem in the campground.

I'll be anxious to see how they work on the PINNACLE we take delivery of in Nov. It comes with 2 batteries for the inverter that runs the fridge between shore power and the truck or geny running.

I would be interested as well. If that setup works better, maybe it is adaptable.

I've done all three.Truck 12v running, converter (now understand that's worthless) and battery only. All three ways it's same story. I'd love to put a 60a-100a 120v power supply on the system and see what it does. Grumpy would the 12v aux power going to system from truck be adequate to power the system? From what you say yes. Congrats on the Pinnacle! They are beautiful. Problem is if Ground Control 2 is under powered for the Seismic, Lippert nor Jayco will ever tell you that, so we will be left with 1000 other reasons why maybe it is, but will never see resolution. I'm hoping for one of us to find an answer though. Have a great weekend.

One thing maybe to try is to use a big battery charger on the battery. That could give you the voltage and amperage boost. I haven't tried that yet.

Pulling the seismic out of storage soon. Dealer swapped control board early winter and never had s chance to test it since, snow was coming and we put her right away. Anyone have any more info or experience with this? I'm planning on installing both batteries when I pull it out. Anyway just wondering what your experiences have been since. Also wondering when they came out with the 2015 4212 if they changed anything in the design, 4212 is heavier so it would be interesting to see if they did. It's still a ground control 2, not a newer 3 or hydraulic like competitors. Thanks all. Also if anyone else since this thread has had similar experiences please chime in.

We have been using the system now for several months and many moves, and have determined that it will level from about 1.6 or 7 degrees off level, but anything more than that it fails. Often, it fails after it has leveled the camper and it is doing its final "grounding" of the jacks before lowering the middle stabilizers. I still think it is an inferior system, and have told many people about its non-leveling properties. Lippert told me that the hydraulic system was their Cadillac and this electric set up is the Chevrolet. It's a shame, really.
