Making of the service module

I became fascinated over working with acrylic and built the Service module from it.  I did not want to use metal above those batteries.  Not wrapping storage batteries with big terminals in metal containers always seems a sound move.

Each battery is separately fused as are all connections that leave the module.  Circuit breakers are provided to disable power.  That factory made battery isolator relay will not close unless the car battery is above a certain voltage and will open below another, lower set point.  This stops all charging once the car is no longer running for a minute.

Over time, a current shunt for the 12 volt metering panel as well as a copper shield over the power supply were added.  It’s getting cramped in there.
