Re: beaver marquis monitor panel
If your panel has the plastic surface with flexible places to push the switches, it is possible that a switch could be replaced but you will need good soldering skills. You could also have difficulty finding the proper switch assembly. Most of those switches are a leaf type and are quite small.
Before you start throwing parts at this, it would be wiser to get a good meter and do some trouble shooting. Trace to see where you have power and where you do not. Have you checked to be sure that there is no fuse built into the panel? If the entire panel works at times and nothing at others, I would look for a problem in the connections, or in the foil path for power or for the chassis ground. Intermittent problems are the most difficult for even experienced technicians. Before I retired, that was the kind of thing that we most disliked.
Have you checked to see if the panel has a good power supply and a good solid ground? Are there times when part of the indications work while others do not? If so, what seems to work or fail together? What tests have you run so far?
Very likely you will not find the same panel available new today, as was used 17 years ago. But you may be able to find one that will work if you have the skills to connect it properly, because most of the indications use pretty much the same kinds of sensors. It could require some modification of the existing wire harness.
Another idea is to do an internet search with the manufacturer's name for your panel. If they are still building panels, they can probably supply one that would work and they could tell you what you need to do in order to use the new one. But this might require more than amateur level skills.
