also saw a puff of smoke come from Z-sus board when i unplugged Z-sus board... and turned it on... am i wrong but how does power get to Z-sus board? isn't it from Y-sus board?

Pretty sure the Z is powered from the Y. Y is on the left, Z is on the right.

Re: Blowing Fuses on this...

How do I check if Power board is culprit? how do i trace it down? cause if it is blowing fuses on Y-sus doesn't that mean it is putting out to much from Power board?

Fuse that keeps blowing in attached picture
