The glow head glowed very bright when my Hot Shot 2 was fresh off the charger, but it died so quickly it got on my nerves. The glow starter is like 6-7 years old, but it has only been charged a maximum of 6 times before I started working on this engine.
I wasn't going to disclose the size of my power supply because it makes me look a little more stupid, but I will anyway. It was a 12VDC 1.5A powersupply
In my defense though, I tried a 9v .5A and a 12v .7A power supply and neither one made it even glow. Which I found kinda strange, but then I just decided to ramp it up a little more, and, well, you see where that got me.
