brunnhilde's bilge ventilation

 

When making modification or alteration to most thing, I developed a habit of not overlooking the utilities what being removed that may seem obsolete or no longer needed. Often when one making altering something the focus is the incoming new, and the outgoing old is regarded as something to be disposed.

I was hoping being able to receive the parts from Amazon for the trailer winch power supply in time to use at the race track. Unfortunately only the battery cutoff switch that I order last arrive first, and the rest was delayed by a day.

Brunnhilde is built on a Mercedes Benz T1N Sprinter that was designed and developed in the late 90s, and mainly as a commercial van with immense cargo or passenger capacity and fuel efficient. Much conveniences of a modern sedan or even SUV or truck were not the the things the designer had in mind in those days. One of these is the ability to operate the front power windows without turning the ignition key to the engine run position.

Carrying a tiny AGM battery in the water boiler compartment is a viable solution to power the winch. That avoid the increase in the trailer tongue weight imparts onto Brunnhilde which has a 500 lb maximum. In the existing arrangement, I intended it as a test of concept and planned to refine the design to further optimize it. As it stands it requires the passenger side rear door as well as the water boiler compartment door both be open during the operation.
