Maybe the board is connected the right way??
Glad that I could be of help with this If you want to help others even more - please update the schematic here ....
Not that I would understand either schematic, but is your board a different principle than this?http://philsradial.blogspot.com/2013/02/glowplug-driver.html
Hi,Did you ever get the Edwards running? I would be interested in knowing how it worked (and a short video would be nice too!)Regards,Mike
I have been reading this very interesting thread as I have it in my mind to maybe build an Edwards 5 sometime in the not so distant future. The suggested glow driver interested me - I am building a 3 cyl glow radial and will be in need of a driver but whether I would be able to cobble together the suggested board or have to buy a ready made one is another question. But out of interest and just for completeness - did the suggested driver ever get "corrected" for want of a better word and the spec proven, ie, did it work?Chris
Hi glorfindel - that is good news indeed! Did it work as shown on the electrical layout drawing, or did you have to reverse the Collector and Emmitter connections as Per suggested?Chris
