Sudden loss of shore power
« on: December 14, 2015, 05:47:04 pm »
We were plugged in at Bahia Honda State Park last week for a little fish, sun and fun. Friday night we went out to dinner leaving two lights and the AC on. We arrived about 3 hours where we discovered that the ac was not not on and the lights were really low, and the low voltage alarm on the Gas detector was sounding intermittently.

There was no AC at any point in the motor home, but power was at the end of the chord. We started the generator but that did not connect with any the motorhome recepiticles. While were were running the generator, the voltage showing in the monitor behind the driver seat, kept roping. The low voltage alarm on the gas sensor kept coming on. The use / store switch was not working and the red light was on.

With no access to Phoenix Cruiser, no access to an internet connection to use this forum, so we were snoutr own. We disconnected the low voltage alarm and ran an extension cord from the box to a fan that we used at night. Otherwise we were boon docking it. I require oxygen so another extension cord went to my concentrator.

I note that when we started the motor home, all the lights went on bright, but when the motor was turned off, back to low power.

Spoke to phoenix cruiser and found that when voltage on house batteries are low the use/store switch is frozen in store mode. We decided to drive home a day early. Spoke to the PC electric guy and he said that the problem is likely gone now that we charged the batteries driving 400 miles home. Went outside and plugged in to the home box and all is well. Apparently if i had just run the motorhome for 20 minutes the switch would have reset itself and we could have plugged in.

Thought you might be interested in know what happened and how PC helped us resolve it.

Sorry you had to go through that... but good to know what happens and how to correct.  Glad you got your concentrator working again!  Thanks for adding to the knowledge base!

Glad all is well now!  Do you know why your house batteries ran down so far?

Interesting chain of events.  Thanks for sharing ge_montana.

Like Barry-Sue is asking, I wonder why the house batteries were not getting charged while plugged into shore power.  Was your inverter turned off?

Greg;

You said, you ran the generator but did not get power to the outlets.
 I check the microwave after starting the generator because the light will blink when the generator starts producing power. When there is no light blinking in the microwave after a minute, I know I have tripped the the generator reset on the control panel at the generator.  You may want to check the reset switch.

As well as the microwave one can use the little red light on the lower right corner of the TV to know when power has been switched over and flowing.   happy Holidays, Ron G.

Ron G.,
Thanks for pointing out the little red light on the TV to check to see that the power is flowing.  I've always been depending on the microwave for that, but sometimes looking at the TV will be more convenient.   2o2
