After tightening the fuel lines the engine should start. The Electrical system on Soma Soma has a typical two battery system. The batteries are located on the port side forward of the ice box. Each battery has a switch mounted on the bulkhead above the batteries. When the engine is charging, BOTH batteries should be on.
Soma has an electric control panel located behind the ladder and above the engine.
The top switch on the port side is the master switch. The Soma has a Farymann single-cylinder diesel engine, which operates an oil pump. The oil runs the hydraulic motor mounted in the sump aft of the mast. The throttle and gearshift levers are separate. The gearshift controls the direction of the hydraulic motor, and the throttle controls the speed of the diesel.
