Trip prep #1, Plan A

In my trip prep hopefully near Feb 20, preparation time is getting tight. A suspected bad charger/inverter is unresolved. A new ‘maverick’ control board for the basement a/c has been installed but as yet untested. Ditto for a new thermostat for the new a/c control board. The control board and thermostat are Coleman items that have been rigged to operate existing non-Coleman ac ‘hardware’, i.e. compressor, capacitors, thermal overload and blowers. When Coleman support found out what I am doing, they ceased returning my email queries.

In order to facilitate troubleshooting I previously install a ground disconnect on my 800 AHr battery bank to assist. It should have been there all along. It was harder to retrofit than to have installed it when the battery bank was assembled. And an assembly job it was, cramming eight batteries into a bay designed for four batteries.

I have been thinking 6 hours and probing 2 hours for the last 3 or 4 days on the inverter/charger problem. Today I thought I would try some work to be sure that the inverter/charger is bad. Not as easy as one may think, or maybe I should say as I thought. A through understanding has to be made because it is imprudent to connect a $1200 inverter/charger into a faulty wiring problem just to see it blow up. I may miss something, but I must try. Call this Plan A. There were previously smaller scope plans, but this one was aggressive.

I was juggling disconnected wires, alligator clips, voltmeter, and a blower plug (as a load) and accidentally shorted the ac pass thru output. Huge sparks showered everywhere from the short inches from my hand. Then after I dropped the ‘mess’, lesser sparks shot from the inverter/charger.. Ok, and I thought there was no ac passthru! I guess it is (was) working

[The inverter/charger has 2 modes. 1. if moho is plugged into ac, the charger is connected to the batteries and all ac plugs connected to the incoming ac. 2. If there is no external ac, the charger is disconnected and the inverter draws power from the batteries to create ac and supply it to a few selected outlets, but not all as it has limited power capability.]

I decided it was time to take a break! More coffee!

When I came into the house to check the difference between the terms ac neutral and ac ground, I found my Vz 4G “hotspot” data modem offline. I had to remove the battery and reset. Apparently the spark shower put enough electrical energy in the router to cause an error in the modem. It is now online again, thankfully.

Now I have to go back and develop a Plan B Test. There is a possibility that if the inverter/charger might have been good, it may now be bad, though it is supposed to survive overloads. But a Leonid meteor shower, not sure.

I am too old for this stuff.
