I recently bought a very nice Guns N Roses pin, but am noticing weak coil power in several areas:

1. The ball often times only make it half way up the ramp and onto the playfield when starting a new game.
2. The left outlane save sometimes takes 2 or three pops before kicking the ball into play (they seem to increase in intensity with each try).
3. When you shoot a ball into the band hole and it shoots up vertically several inches and back onto the playfield, it can be weak. It always makes it up, but sometime just barely.

Are all these low power issues because of one larger issue? I’m not vary versed in my tech language, so this probably seems vague. Is there like a new power supply I should install to give these coils more pop? I was able to play about 20 games with various degrees of coil power, but now the ball launch at the start of the game won’t even get the ball 12 inches up the ramp.

Thanks in advance for the suggestions!

This is why I love you all so much on Pinside -great tips and to-do's. Thanks!!
