as for the sine wave stuff, my tv is a Sansui 32" LCD (model HDLCD3212C). I dunno if it needs pure sine wave or not, but If I can get a smaller one at a good price, I was going to go that route.

I do think the single pole issue on the switch may be a problem. Perhaps some other sort of switch would be better suited. Any suggestions for a switch to select from two sources of 120V?

This is the type of switch you would need (double pole double throw).Switches | Wall Switches | Industrial Grade Toggle, Double Pole, Double Throw, 30A, 120/277V AC | B211353 - GlobalIndustrial.com

Power sources for many electronic devices. Originally
they were all simply small transformers in a little
(usually) black box with a built in AC plug. when plugged
in to an AC outlet, they looked like a "wart" on the wall.

As they evolved, they became transformers with a linear
regulated DC supply, then finally morphed to switching
regulators. All versions seem to still be still available, with
switching regulators becoming more dominant.

In almost all cases, their job is turning high voltage
(117VAC/234VAC) into low voltage DC usually 3VDC
to maybe 20VDC........

cheers,
johnd

I burned up my first inverter trying to use a single pole double throw switch to accomplish what you are trying to do.


I should have used the double throw double pole to switch BOTH ground and hot wires to the load circuit with an "off" in the center to keep the power TOTALLY seperate from each other.

Yeah, it seems to me you guys are right and the double pole would be a much safer bet. I'll go that route.

That said, phase one of my DIY is done. I was going to go to two 6v batts and went by SAMs to check them out. They had some energizer 220Ah 6vs. They looked good. Then I saw some energizer 29HM Deep Cycle 12volts. Hmmm.. 125AH each... I was torn...

In the end, I wnet with two of the 12volts. They should give me more AH, though probably wont last as long, but they came with a 1-3 warranty. The plus side being if one does go belly up, I stll have power if I take it off the rig.

I was able to get them both in my existing Battery Compartment...Just.. But it was noice to do so because I was dreading the loss of storage space in my pass-through. I wired them in parrallel with some 12" @2 battery cables I got from Autozone. Hooked everything back up and NO POPS and I didn't let the smoke out of anything!

Next will be a new 12v outlet near my bed so I can run my CPAP machine from that instead of the outlet across the room by the tv that I have been using.

That is what the Captain meant to say (LOL).
The white and the black wires; not the bare metal ones. <smile>
