Are you using a true-RMS voltmeter to measure the DR's output? The DR's output is modified sine wave, and a cheap average reading AC voltmeter will give you a reading of 90 volts or so. Alternately, if you have an oscilloscope, you can verify that the modified sine wave is around 170V peak to peak. It should alternate in segments of -170, 0, +170, 0... The duty cycle and peak voltages will vary with the inverter load.

Plugged camper into 120 volt everything works electrically except ceiling lights dont work

* Check 12 volt DC system (may be camper battery or car battery, though most only use the camper battery.)
* Camper may be using 12 volt DC lights so it can be turned on while your on the road or not hooked up to an 120 VAC or 240 VAC outlet.
* If you are using 120 VAC lights then check the neutral line (note; HIGH voltage here. Get help from an electrician or at least the RV park handyman.) The problem may be at the outlet (the RV site's problem) or more likely in your plug or cable (the big cord) as it does get abused, run over, kinked, etc. Need to have it checked by an electrician.
* Check the light bulbs; is it seated properly? Replace if burnt out. Have electrician test if there is power at the socket.
* Final; Be safe and have a qualified electrician service your camper.

I have a customer that recently replaced his generator, problem is , he got a 120 VAC output. He has 2 SW 4024 for 240 VAC output. Can I hookup the 120VAC to the master inverter, or should I get a...

Hello,

I will accept the second option which is getting transformer.

Go ahead and get a transformer in order to step up the voltage. This is better than hooking up the 120V AC to the master inverter.

In summary, get a transformer to step up the voltage.

I hope this is clear now....

Good luck.

Can I use this timer, using only 120 vac to supply a 120 to 12 vac transformer?

no this timer is rated for 240 volts so therfore the clock motor is 240 volts. You will need to purchase a 120 volt clock Good luck!

How to test for 24 vac between R and C

Yes you are right the control voltage of your furnace is 24 volts. Really without a load on the transformer usually runs 28 volts then you put a load on it and it drops down to 24-26 volts. Check the voltage between the R terminal and the W terminal with the selector switch in heat mode. Or move the thermostat switch to heat. R to C would do it also. You could also do the voltage check right at the transformer one side of the transformer is 120 volts and the other side is 24. Look for the black and white wires that is the 120 volt side the blue and yellow or off colors is the secondary side.

Now if it checks low say 24 or 22 your gas valve needs min. 24 volts to hold open the valve that allows the gas to flow into the burners. So if one of the symptoms is related to burners come on for about 3 to 5 min. then shut down and the fan keeps going it is loosing the necessary voltage to hold open the gas valve.

One more thing make sure the air filter is clean as this will cause the heat to build up in the heat exchanger and hit the high limit safety device and cut the gas off. Until the air cools enough to allow the high limit to reset then the gas valve will open and start the process all over again. Dirty A-Coil will do the same thing as the air goes through the coil to get to house. let me know how it goes ken

Cordless vac won't hold a charge

Like all batteries after a while they go bad/will not hold a charge. especially the kind that is always plugged in/always charging, like electric shavers, cordless vac and so on.
get a new battery
