multiple electrical issues at once

[rosannemarie]

A newby living in our coach almost a year now…in a park w/ 50amp service for two weeks. Last night noticed light was dimly on in the ‘off’ position of water pump and storage bay light. Heat pump zone 1 began to kick on but suddenly stopped; multiple times this happened-wouldn't stay on. Refrig interior light was out when opening door, then refrig exterior light off indicating frig turned off. Turned it back on, but it did not stay on. Turned zone 1 off, zone 2 on; worked fine for about 5 minutes, then same behavior as zone 1. Breaker box switches looked normal. Turned breaker switches off/back on to ac units and refrig. No change. Turned off 50amp service. Light inside refrig returned to normal, same on water pump/storage bay switches. About 15 minutes later, same behaviors occurred. Turned 50amp service back on and all issues continued. Turned off 50amp service, turned on furnace and called it a night. This morning fridge light is on inside/outside and switch lights to water pump/storage bays normal. Too early for neighbors and cold to try heat pumps and haven’t turned on 50amp service yet either. Many pennies for your thoughts as we prepare to visit the service center -

It's almost certainly a problem with the pedestal power, if turning off the power fixed things. I don't know the CS line. Do you have 30amp or 50amp service? What was the pedestal voltage when you were having the problems? Does the electrical panel have a display that shows the incoming shore power voltage? Or do you have a meter that will show AC voltages?

Since all of the stuff you were describing is driven by 12 VDC, I would first check the Battery Cut-Off Solenoid (which is activated with the Salesman Switch) or just bypass the damn thing as they are a waste of time and give people lots of headaches. The second thing to check is the House Battery Disconnect Switch to make sure it is making good contact and all connections are tight and secure.

Hmm. 12v systems. Turning off pedestal power would remove power to the converter, which would stop charging the batteries. Does the 12v system get fed directly from the batteries, or is it like an inverter where it gets fed from the converter unless there's no input power (like a transfer switch)? I wonder what voltage the converter is putting out?

It did fix things temporarily using just coach power. Have 50 amp service. I don't know meaning of pedestal voltage. Just turned shore power on. Panel Control system above door shows 50AMP, 4.2 AC AMPS, W/H, AC-2, AC-1 - all lit. Zone 1 Cool/Heat Pump came on fine; so far running well for 3 minutes so far. I don't have a portable voltage meter (yet...).

Pedestal voltage is the voltage at the shore power connection (the pedestal). Is there anything on that control panel that shows AC voltage? I would think it would be near the AC amp display.

[rosannemarie]

We have a Freedom HF1800 inverter and 4 Lifeline sealed batteries. I have no idea how they 'talk' to what.

[FlyingDiver]

Well, rats, I just found a picture of your Power control panel, and it doesn't have voltage readout. Get a meter.

I would suspect the convertor is the problem.

[rosannemarie]

Battery meter reads 14.2 volts but almost instantly goes to 13.0 volts. Should shore power be off to check it?

I will get one!

You said turned on 50 amp power isn't your shore power cable plugged into pedestal, so why are you using everything off inverter and not the 50amp supplied.

My first reaction was battery charger not working and it got reset with disruption of the 50 amp service but finding things working in the AM without shoreline power indicates your batteris are probably in good condition.

A voltmeter across the batteries is where I would start and then on to DR4Film (Richards) comments.

You are losing the 12 volt path which probably includes a solenoid. Cycling things on and off can cause a faulty solenoid to land on a clean contact versus one that is burned.

If your microwave lights up and your air conditioners work then the incoming voltage is probably ok. However your air conditioners rely on 12 volts to run the electronics.

Grab a meter and get a measurement and find any large solenoids you can find. On a later model HR/Monaco the relay DR4Film refers to is under the drivers compartment outside.

Is your battery cut off switch on and always leave it on when your using your coach.
If you can start your Gen is everything working normal with it in service?
