Glow Plug Control Resistor

Glow plug control resistor for Isuzu diesel engine.  Fits the following engine models:  4FA1, 4FB1, 4FC1, 4FE1, and C240.  This resistor gets hot (glows red) at the same rate that the glow plugs get hot, and when the coil glows red, you then crank over the engine to start.  This is basically an indicator to tell you when the glow plugs are hot.  This is the unit that comes in the Isuzu industrial engine panels for the previously mentioned engines.  We have a few of these at this special pricing!  When they're gone, we'll have no more at this price!
