Hi Sail Princess,
You mentioned that a couple of months ago you replaced the solenoid and regulator out in you propane locker, but a quick look at the manufacturers website noted the following comments:-
“ Will my old components for detection system work with the new ones?
The new LPG Detection Systems (P/N 1300-7761-KIT & P/N 1300-7760) Components are not interchangeable and will not work with older LPG Detection Systems (P/N 1300-7757, P/N 1300-7758, P/N 1300-7757.5 & P/N 1300-7758.5).”
and a bit further on under a different question it notes :-
“ How do I test my LPG Control and Detection unit?
Testing a LPG Detection system for function. You can test the system by using a propane source (disposable cigarette lighter or a 1 Lb. disposable propane bottle) at the sensor, discharge a burst of propane at the sensor, the sensor should alarm and send a signal to the panel to shut down the system. It is a good idea to check all wiring connection for possible corrosion and/or loose connections.”
So in regard to the first point above could it be that your new solenoid and regulator components are not entirely compatible with your older gas detection system ?
While in regard to the second point, the suggestion that it is a good idea to check all wiring connections for possible corrosion or loose connections could be part if not all of the answer to your problem. Your Bavaria 40 you mention is a 2002 boat. At that time Bavaria used ordinary copper wiring for many, if not all systems onboard. In my experience on a 2002 Bav 36, I found that the directional control cable for one system onboard (windlass to solenoid) was corroded throughout its entire length, thereby making it difficult for the required signal to reach the solenoid. This prevented the windlass up/down control from working until I changed the old cable for a new one that used tinned copper wires. Thereafter there were no further problems. Likewise with the cables supplying current to the mast lights, here I found that cable was so corroded, again throughout its entire length, that while I had sufficient voltage reaching the lights, the corrosion prevented the required current, or amperage, to reach the lights in sufficient quantity such that they would not light up. A new cable with tinned copper cores made all the difference.
Last time I read one of your postings you were headed down the west coast of the USA towards central America where I’m guessing that getting hold of tinned copper wire might be difficult, but you might be able to get new coppet cored wires which you could connect in temporarily and loosely across the deck between components just to check out whether new wiring might make the difference you need before going to the expense and trouble of laying in new tinned copper, just a suggestion !!
I wish you well and hope this helps, Salty.
