I've just installed (had installed to be precise) a gas water heater
to replace the old electric heater. One of the benefits I thought
I'd get from this and the gas furnace was to eliminate problems with
power outages - especially worrying with all the storms at the
moment. But I didn't realize until the install was underway that the
heater needed electric power. (I was earlier thinking about a
tankless water heater, but it didn't pencil out, and I guess I didn't
connect all the dots.)
I don't have a generator, but when I saw an ad for a Kawasaki 800w
inverter for $40 I thought it was worth a shot. Hopefully it would be
able to power the fan (2.8 amp on the plate), and maybe run a TV as
well. But experiences so far haven't been positive.
I connected the inverter to the car battery using the supplied leads.
I used a jumper cable to add the ground lead (why didn't Kawasaki
supply one?). Then connected to the gas heater.
Unfortunately the heater doesn't work. Moreover the status lights
identify the problem as 'wiring error or high resistance to earth
I wonder if the car chassis needs to be connected to the house
ground. I don't see a ground wire from the gas heater (and the power
just comes from a 3 pin grounded cable), but maybe I'm missing
something. Would connecting the vehicle ground to the house ground
cause any problems? Or perhaps I just need to ground the water
heater to the house?
