My rv has a 12 volt valve for the propane tank with to much parasitic drain, is there a way to leave the valve in the open position without the battery drain? ( it has a manual shut off) I tried a large magnet, didn't seem to work. the only way to open the valve is with the switch on , using 12 volts.

First, you shouldn't jump to conclusions.How do you KNOW that, have you measured it ?What device does that valve serve ??There probably is a 12 V valve so that the device can operate "automatically" and you wouldn't want to defeat it.

The device is on the propane tank so it serves everything in the rv, but in order to use the propane you have to turn on the 12 volt valve, yes I have measured the drain. I would like to keep the valve open without using any 12 volts & manually turn it off when I am home. This is what the valve look like http://www.ebay.com/itm/SOLENOID-VALVE-PROPANE-MOTOR-FUEL-TANK-12-VOLT-LOCK-OFF-VALVE-12V-LPG-LOCKOFF-/141730711967

If I had one of those on my camper, I'd be throwing it away and reconnect to a standard manual hose and pressure regulator.I've never seen one of these in service before, but could you simply remove it from the line and plug your hose directly into the tank and that way you would not have it dependent upon a battery? In other words, go back to the manual old fashioned way?

I agree & will do that unless someone knows an easy way to keep this valve open.

This is a big issue with cruising sailboats that must have the solenoid. For those who do not understand this issue, when energized the solenoid gets so warm it is impossible to grasp it tightly without yelling.Between stove, hot water heater, refrigerator, and space heating how is a person supposed to manage?Sailboats are minus, refrigerator and space heating duty (they use diesel). So the issue is solely to energize and de-energize with a touch button latching relay.With an RV that has no bilge to fill with LPG gas and explode the necessity of the solenoid becomes unclear. Think about it...
