mitiempo Check the solenoid. Only 2 wires - if it opens when power is applied it's ok. If not replace it. If the solenoid is ok, replace the sniffer - after asking around I don't think they are designed to be repairable.

davewild I would encourage you to consider getting a professional to look at it if your unsure about it. LPG and electricity can be a dangerous mix. Switches almost always arc to some degree as they make contact and I'm not sure that's what you want if you get a leak in the gas line.

donradclife The wires which are feeding the switch ('in' side) have a weak connection, and when you load them up by closing the switch the voltage drops to zero--the problem is not with the switch.

Not meaning to insult you, but we had a fellow on here recently who had forgotten about the other LPG switch on the DC master control panel.

I've never had to delve into the remote solenoid switch. But we've lost propane twice and in both cases traced it to a malfunctioning solenoid. However, the light on the remote switch always worked properly.

I'm guessing that the solenoid is not opening. With the switch on out+,out- should be 12 volts to open the solenoid I believe and yours is showing 0 volts. I don't know if they are easily fixable or even openable to get at the electronics inside. Mine has 2 screws on the back but I've never opened it.

What i do not get is how the voltage drops to 0 on the IN side. My understanding is that should always remain at 12v.

Troubleshooting LPG Control Panel

I am trying to troubleshoot a propane problem. I am testing the LPG Control Panel and got myself confused. The panel has four wires on the back: IN+,IN-,OUT+,OUT-

With the switch off:

IN-,OUT- have continuity
IN+,OUT+ no continuity
IN+,IN- about 12 volt
OUT+,OUT- 0 volts

With the switch on:

IN-,OUT- have continuity
IN+,OUT+ have continuity

So far this is all as expected. But what I did not expect is with the switch on:

IN+,IN- 0 volts
OUT+,OUT- 0 volts

The only way this makes sense to me is if turning the switch on creates a circuit with less resistance than the meter. Is this possible? Am I missing something or using the meter wrong?

This is a cheap analog meter.
