Slg ul problems

[Sami4]

2 of my friends have slg ul's. We went to our field on Saturday and both didn't work.
The one just simply won't turn on, tried new battery's and a bit of card to push it up.
The other is leaking out the back of the gun, think that could be something to do with the bolt
Any help would be appreciated
Cheers, Sam

lube both of the orings on the bleed button and all on the bolt, should do the trick. my mates slg had the same problem, i just pushed the bleed button back before i put it back together .

For the board, use an ammeter to check if current is flowing through it, if it doesn't show want read anything then the board needs replacing! Also check the connection from battery to board to check if a connection has come loose

Hope this helps!
