M16 Not Working

[panzergrenadier]

I'm currently in the process of converting my M16A2 into a C7A2.
Seeing as I switched from full Stock to Collapsible, I Figured I'd rewire it to the front. So I got myself a G&P Front wired Switch assembly, installed it, put 'er back together and voila! Front Wired... Got a Mini Battery, Charged it and I find my rifle not working at all...
Checked to see if the wires were properly connected to the motor, they are and still no... Nothing...
Anyone got any pointers or solutions?
Thanks

*EDIT* Fixed it... The fuse was burnt out... both the ones I have...
