John I do not have a Boler
17 so my answers are based simple knowing and having been in a few bolers and owning a Scamp
which are often wired up much the same.
There should be a rocker switch for your water pump. Not sure where normally it was found stock on the 17' but usually the switch is located in the kitchen area on the front or the end of a kitchen cabinet. It is also very possible your electric water pump was not originally on the trailer and was added after the fact - the trailer came stock originally with a hand water pump in the kitchen, so you may need to do a bit of looking around under the sink area etc to see where a previous owner may have hidden it.
Re the light
issues. Its hard to know what the previous owners of the trailer may have done in regards to your wiring/lighting set up. Your trailer may or may not have a converter originally. The original converters if it had one where often mounted with the face and controls showing on the outside of a cabinet. Sometimes found on the face of the bench under the front table or on the face of a kitchen cabinet. Due to the age of the trailers you do not see to many of the original converters still in use in many bolers today. You can see a picture of one at Bolerlife.com
. The originals did have a switch on them you needed to use when switching from battery
to 110. If the converter has been upgraded you may want to check under all your benches for a converter hidden away as there are many that are not mounted flush to the cabinets face and are simple a box hidden away in a hatch. If there is no converter then none of your 12 volt lights will work when there is no battery
onboard. I also know of a few bolers were someone has installed only a battery charging system so the 12 v lights still did not work when plugged into 110 power and no battery.
Some info including appliance manuals etc may be found in the Documents Center
on this forum - the link is on the main page on the left.
In the Documents center there are a number of Boler
manuals - keep in mind depending on where your trailer was built there are going to be differences. There is one for a 1979 Boler that includes the 17'
It includes a wiring diagram etc for the 17'
