What is the correct voltage for a glow plug driver? I have just installed a Gryphon Auto Booster. It has a jumper that you can set according to the input voltage but it doesn't seem to make a huge difference, with the range of output voltages being about 2.85 down to about 2.5v on the lowest setting (this is according to my multimeter). I thought the correct voltage is 1.2v so will I blow the plug if I run it at 2.5v? I haven't tried starting the engine yet but if I take the plug out and run the Booster it looks like it has a nice healthy glow but doesn't look to bright to me so perhaps it's fine at this voltage.
Thoughts please?
