viper 5701 in camper.solar triggers alarm

Hello. I have a 1997 ford e350 (former) ambulance, which I have converted into an 4x4 camper. I had the Viper 5701 with remote start installed a few years ago by a guy off craigslist. The alarm worked well unless I was plugged into 120v power and the inverter/charger is charging the batteries. More recently, I added solar panels with charge controller. The alarm again false triggers and is pretty much useless during the day now. Previous installer pretty much wants nothing to do with it. Symptom: Alarm full triggers within 20 minutes of either of the chargers starting. It is reported as a Shock Sensor problem. So, is the brain seeing a voltage drops and/or spikes and it triggers the shock sensor? If so, is there a way to turn off voltage sensing? The brain is within 2-3" of main power lines (00awg) and lots of other wiring nearby (but tidy). Too close? The brain is grounded to a main shared ground block (part of the ambulance electronics).   Should the brain have its own unique chassis ground? Ambulance wiring is sound. Any other ideas? Any help would be greatly appreciated.

I am assuming you mean "starts charging" that it is the solar units and not a generator of any kind that could produce physical vibrations. Right?

Thinking about it electrically the alarm may indeed monitor the voltage on the ignition line and sees 12v +/- when armed and since most 12v chargers charge at 14v +/- that spike is probably making the alarm think that the vehicle has been started. Disconnect the ignition feed on the alarm and see if that stops the false trigger. Post back with the results of that test.

If the alarm still triggers disconnect the shock sensor and see if that stops the trigger. Keep in mind this is all temporary testing.

To master and control electricity is perfection. *evil laugh*
