"This one is for Guy, Brian, and BTDoctur, but if anyone else has any suggestions, please feel free to chime in.
This is the same Cobalt I'm in the process of resurrecting. When I first started working on it, the trim would not work at all. We jumped the positive terminal at the 110 amp fuse to the up Blue/White to bring it here from NY. I then replaced both solenoids and the resevoir. Then, it would sporadically work when in the water, especially the UP on the throttle handle. Most of the time, the trailer and down would work. Sometimes when running, the UP would not work and I used the trailer button to trim it appropriately.
Now, nothing works, except jumping the terminals. I just replaced the trim sender and limit switches, and verified they are working correctly. The sender sends to the gauge just fine, and the limit switch has continuity when placed in the proper position.
I have 12v on the red wire at the throttle switch, but nothing at the 3 pin connector at the pump assembly. All contacts have been inspected and cleaned.
The 20 amp fuse is good, the 110 amp fuse is good, and everything else I could check.
Now, here's the kicker. The blue/white and green/white coming from the connector to the solenoids is reading a ground. WTF. I thought these were supposed to have voltage when the trim switch is up or down. I can't find any shorts, nor am I blowing any fuses.
Any help would be much appreciated. Thanks!"
