Does anyone with an older ( 2000 ish) coach remember how they changed over from a 4 wire propane detector to a 2 wire? From what I have read, the requirement for the 4 wire w/ shut-off solenoid was no longer required in the early 2000's and has become hard to find. My 2017 dated detector died recently and I could not access propane. So I replaced the solenoid with a 3" brass nipple and attempted to wire in a 2 wire detector which are widely available.
My 2001 Marquis had a red, a black, and an orange wire (with 12 volts). The original 4 wire detector had a red, a black, and 2 white wires. One of the white wires on the original detector was connected to the two red wires. The two black wires were paired. And the orange wire (w/ 12 volts). would have been paired with the other white wire on the original 4 wire detector. Wish I had taken a picture before I disconnected, but I didn't-lesson learned. Don't know if the two white wires on the original detector are the same.
So I wired the 2 wire detector ( w/ only a red and a black wire) as follows: red to red and the orange( w/ 12v) to the black wire.
When I originally connected the 2 wire detector the green light was blinking. When I pressed the TEST button, the red lights and alarm came on. Now the green light is solid green and no longer flashing. Is this how it should be?
New problem: I just turned on the propane bottle in order to light the stove and I have a significant leak in either one of the two pressure regulators or between the two regulators. Not sure which yet. I have a small regulator stacked above a larger one. I believe it's a higher pressure regulator dropping pressure to the larger lower pressure regulator. Are these two regulators made as a unit or are they made individually? I did notice that the connection between the two was loose and attempted to tighten it. I will investigate further. As a former pipe fitter in a commercial gas field, I tape and dope all threads, and bury the threads when making it up. So I know it wasn't my connections. I would not think that a diaphragm would suddenly tear but who knows, they are 24 years old.
Any suggestions on where to purchase a new propane regulator set would be appreciated. Also any suggestions on my wiring issue would be welcomed.
Thank you for your help.
Respectfully,
MIke Sulley
