Voltage Drops

The battery has nothing to do with 120 volt power. If you are getting a considerable voltage drop, the wiring is at fault somewhere. It could be a bad connection within the RV or inadequate wiring anywhere back to the main panel that supplies your power. Without knowing how your power is supplied, I can give only general ideas. Check the voltage, under load, along the way beginning as far back to the source as possible. Continue along to you find the voltage drop. It may be just that a too light, or too long of an extension cord is used. Describe what you have for more help.

If you have a poor connection within the trailer, that is a fire hazard. My KZ had all the wires loose behind the twist-lock cord disconnect. I eliminated the stupid thing.

Please do not feel badly, you were trying to help with a suggestion, many of us have done the same thing including
myself so don't beat yourself up, we all learn from our mistakes

Hope to see you this summer at the Kz Rally we will be there hope you will be there too

The converter uses the 120 volt AC power to supply the 12 volt DC to power the battery charging and all of the lights as well as other circuits. It will pull some amps, especially if the battery is in need of charging. Again, we need to know if you have a sufficient supply of 120 volt power to your rig. You need a volt meter to measure the voltage at the source and within the RV. Report your findings so I can help. You should get a plug-in voltmeter anyway so that you know the voltage at any time. A cheap handheld, and sometimes free with coupon, is available at Harbor Freight.

Larry, I guess you meant a 50 amp outlet, a 30 amp has only one “leg.”

Without voltage readings, it is hard to help the poster. Perhaps he can supply the needed information.

Again without voltage readings, it is hard to help you. Perhaps you can supply some more information

When you stated that the Tech working with me has checked the voltage that is being supplied, what did he find
voltage wise.

a. Did the tech checked your power cord to make sure it was ok (no brakes) ?
b. Was, is the power cord large enough to supply the correct power to the trailer ?
c. Did the Tech check the plug end of the power cord to see if all the legs/wires were connected an not burnt or loose?
d. Did the tech make sure the power cord could supply enough current to be sufficient to power your trailer ?
e. Did the tech check to see if there was any loose connects behind your power cord or at the fuse panel.

Other questions come up;
a. Did the Tech plug in any appliances,
b. What were the appliances an how many?
c. Was there an voltage drops when done,
d. What were they ?

More questions come up;
a. Is this a problem only at home or while you are at a camp ground ?
b. Is it a problem at more than one camp ground or just one ?

All these things matter when trying to answer an electrical question, not saying the tech is not good but when
checking an electrical problem like yours he should have started at the plug end where it is plunged into the power
pole, marked those voltages then , question answered like this can also help track down your problem ...

Once he did that then he should of looked into where the power cord hooked to the panel inside your trailer, once
he did that check for the voltages coming out of the panel to every outlet outlet an appliance an made sure they
were tight in the panel an supplying the correct voltages to those appliances.

If he knew there were correct voltages at the panel he should have went to each outlet an checked those voltages
to make sure they were correct, once this was done then he should have check the voltage drop to each appliance
at the panel when they were turned on...

Tracking down a problem like what you have is not an easy job, it may take hours if done right, this is not a 30
minute or one hour job unless something sticks out like a sore thumb ...

This is why lynnmor ask about what the voltages were, thus like a good detective could help you track down your
problem so it could be fixed ...

Please, Please, Please give us more information because it's like shooting ducks in the dark, you can hear them
but you can't shoot them because you can't find/see them LOL
