I have an old Cox .020 with a good glow plug; need some help getting her started. I have a small charger pack consisting of 2 AA alkalines which shows to be generating only 2v with 2 batteries together (even new ones wouldn’t be more than 3v).
I know that 9v would be bad, 12v, etc., but will 2-3v really be an issue burning out Cox glow plugs? Will it shorten the life of the plugs much if I regularly use 2-3v..??
