E-MR1 Charging Issue
 

I just bought a new E trigger frame for it. After installing it i went to charge my 9.6v Spyder battery but the light wont come on when plugged in. Am i wrong in thinking that I should have the gun in the OFF position to charge the battery?

Am i not doing a step? The light comes on in all 3 of the other positions so i now the light works. As i can tell it isn't charging the battery either
