Propane Shut Off Solenoid Drains House Batteries

[vacuumbed]

Hi all,
Has anyone with an RV equipped with a propane shut off solenoid notice that when your propane is on that your house batteries will drain rapidly?

Thanks in advance

My propane tank is mounted under the coach next to the driveshaft, thus my tank has an electric shut off solenoid and remote fill.

I can replace the tank with a non remote fill tank, but I doubt the guy at Flying J that fills propane will want to crawl under my RV to fill my tank.

WHICH system and solenoid are you talking about???? There are 2 systems
1. The OLDER LP detector systems that when the LP sensor tripped shut the LP OFF at the tank on the output side of the regulator
2. System where the LP tank is mounted where the FILL hose cannot connect to the tank and they install a remote fill hi pressure hose and remote 80 percent bleeder valve. THIS system has a HI pressure solenoid BEFORE the LP regulator that has a standard OFF/On 12 volt switch to turn the LP ON and OFF. You do NOT have the standard turn handle valve as the tank is mounted in the center or under the RV chassis frame.
Last, you cannot change the ASME tank to a non remote tank where ANY filler person has to crawl underneath to fill. THAT violates almost ALL LP codes and regulations. That is why they have the remote fill system and 12 volt On/Off solenoid. Only a FOOL would crawl under an RV to fill the LP tank. And only an Ignorant fool would install such a system for someone.

The remote fill switch is normally on the fill valve and for the output of the propane and is shut off after filling.
I will try to double check this!
Might read through this.

I need to check the model.

The switch stays on all the time, if I turn it off then I have no propane.

Your furnace is a big user of power.
Refer does not use that much.
What is the model of the Safe T Alert unit?
Does the remote fill switch get shut off after tank is filled?

The Safe T Alert was factory installed.

If the person that installed the Safe T Alert, didn't replace the solenoid, you have found the problem or a contributing factor.
The CCI solenoid was installed in series with the LP detector.
The safety alert has a solenoid output.

I stand corrected. Looks like I have a 1.0 amp draw from the Safe T Alert. Makes sense now why my house batteries are always dead.

My RV is a 2005 Chinook, but it may have been built in 2004.

It does have Safe T Alert. I miss my old RV. A lot of this technology frustrates me. A lot of newer stuff is over engineered.

If you have a CCI system, the propane solenoid valve draws 168ma. or 0.168 amps. That's 4.032 amps in 24 hours. If you have one of the newer Safe-T-Alert systems, the propane solenoid valve draws 1.0 amp.

The Safe T Alert isn't the issue. The trouble is that if I want to use my propane at all, fridge and furnace; my batteries will take a hit. In 12 hours, I'll go from 12.7 volts to 10.5 volts. I also have two house batteries. It doesn't matter if the batteries are new or old, they will drain unless I turn my propane off.

The "fail safe" configuration is that the solenoid is "on" all the time except when the LP sensor senses LP, and then it shuts down. Don't know how many times such a system has saved an RV from a fire. Anyone care to comment?

[enblethen]

Yes, most of the LP solenoids draw power when the LP detector is on. It should not drain "rapidly".
Make and model of LP detector?
Careful if a CCI was changed out with a Safe T Alert!
