Blowers on my Express 30 have been intermittent over past two years. Now they stopped working for good. I ran a jumper from pos side of battery to each motor with no result. However, when I ran the jumper from the negative battery terminal, the blowers came on with either switch
Therefore, I have a poor ground that's common to both blowers. Wiring diagram in the owner manual is of no help. Anyone know how the grounds are run in this boat?

Most likely corroded terminals or the copper wire at ring terminals?

If you've not already solved this, you might take a look at your automatic fire extinguisher. It is wired inline with the blowers to shut them off if the fire extinguisher is discharged so no additional oxygen is added to a fire. Is the light on your fire extinguisher status lit green when your key is on? If not, that is the issue. If the fire extinguisher status is good, there is a relay near the fire extinguisher that you might have a look at.
