Glow Plug Battery

When starting the FS 400, it is necessary to use a glow plug battery of large capacity, 10 Ah or greater to heat 5 glow plugs simultaneously. A heavy duty 1.5 volt dry battery or preferably a 1.2 volt rechargeable NiCd battery may be used. A 2 volt lead acid cell (accumulator) may also be used but only if a method for reducing the voltage at the plugs is in place, since the plugs are only rated at 1.5 volt. See Below for instructions for 2 volt.

• If a lead acid 2 volt lead acid rechargeable cell is used, it is necessary to reduce the applied voltage at the glow plugs to approximately 1.5 volt. The recommended method is to insert an appropriate resistor in each individual plug lead. It is seriously discouraged to use a rheostat attached to the 2 volt cell, or to use extra long leads of at least 2 meters in length, to obtain the required drop in voltage. The disadvantage of this system is that if 1 glow plug should become disconnected, voltage to the remaining 4 glow plugs will be increased dramatically and may cause burning out of the elements.
