Hello, I need help with this. I need to turn an old bike lead-acid battery to a model glow plug driver. I think the current must high in order to get the glow plug glowing. Could i use a power transistor and a zener? Any help is welcome!
I obviously can't speek for anyone else on the forum but to design a circuit it might be helpful if you could tell us the voltage and current requirement of a glo plug. I was thinking they were 1.5 volts. Perhaps you could apply a 'standard' supply to one and measure the current drain to get this project going.
Easily done with a 555 timer with a variablem-s ratio to give the requisite current......... followed by a power transistor or mosfet
If you struggle with finding a cct let me know I'll dig mine out.........
Glo plugs work at around 15-2v with a current draw of some 4 amps
