|You can easily build an onboard glow igniter using a single sub-C rechargeable battery cell and a few simple, inexpensive parts. First, solder a battery bar to each end of the cell, and strap the cell to the chassis in an easy-to-access location. The battery bars will give you a spot to which you can attach leads from your charger, so you’ll be able to recharge the cell without removing it. The next step requires a section of wire, a crimp connector and a small, two-prong, momentary pushbutton switch from RadioShack. Select a crimp connector that fits snugly over the electrode end of your glow plug but can also be pulled off when required. Crimp one end of the wire onto the connector, and solder the other end to one prong of the switch. Solder another length of wire from the other prong, and attach the other end of the wire to the positive end of your cell. Finally, solder a length of wire between the cell’s negative terminal and the engine block. It is easiest to use an eyelet connector (also from RadioShack) and attach it to any steel screw on the engine. This wire will serve as a ground and will complete the circuit. Now, when you want to start your engine, just hold down the switch while you pull the starter cord or use a starter box. You can even wire 2 cells in series for more voltage and starting power.
