The once pretty standard power panel that is inputted by the 12 volt battery used for the starter also provides 6 volts for an electric fuel pump and 1.5 volts for a glow plug driver. My panel made by Hobbico (Tower) has a meter tied into the glow driver so it reads the current draw, and as a result shows if the plug is taking current (not burned out). The panel uses a cord ended plug connector that Du Bro, for one, makes. I use my power panel for all three and only charge the 12 volt gell cell battery once or twice a season.
