Hi Guys, I'm back and still trying to fix this TNT unit. I posted ealier before I went to the parts store, but I don't see my post so I must have hit something wrong. So this is what is happening now. Before taking it off the boat, I decided to check the relay, which actually is a solenoid, not a relay. Found some corroded wires so I cleaned them (actually cleaned all of the wires really good). After cleaning them, I now have motor sound when pressing the down button, but nothing pressing the up button. The marine shop said it was probably a bad solenoid. I am able to bypass the solenoid by using a wire and touching the 2 large connectors on the top of the solenoid, which does give me sound from the motor. So I went ahead and got a new solenoid, got a matching one from the auto parts store since the marine shop can't get one in stock til next week. Then got 2 tubes of fluid and started refilling the hydraulic reservoir. Squeezed in some fluid til it started coming back out, then let the motor down manually til it hit the hydraulic plungers, then lowered it the rest of the way with the down button, then tried to raise it (by bypassing the solenoid since the up button isn't giving me any results), then repeated that about 4-5 times to get the air out. It goes down no problem, but still won't come back up. I raised the motor manually and locked it up, and using my wires to bypass the solenoid, raised it using the TNT motor, and the hydraulic plungers are coming out, and look to be coming out as far as they can, but with the weight of the motor on them, they won't come out to raise the motor. I am noticing when I raise it manually, the hydraulic cylinder in the center between the TNT motor and the cylinder I put the fluid in, comes up a lot, which is what I'm guessing gets the motor up into trailering position, since those two other plungers can only come out so far. Initially when I started this thread, I was wanting to know how to disable the whole system to get my motor down where it should be, but now that I have discovered the TNT motor is not bad, like I was told by the first marine shop, and I have it going down, I don't wanna quit. I want to get it going up now. So, does anyone have any thoughts on why it won't go up now? To repeat myself, it will go down using the down button, and when I use a wire to bypass the solenoid, I get motor sounds where it should be going up, but the hydraulic plungers are not going up (coming out) with the weight of the motor on them. The 2 hydraulic plungers in the center are coming out if I give it some assistance or when I already have the motor raised manually, and they will hold it up when I let go, but they will not bring it up without my assistance with the weight of the motor on them. Any Thoughts???? I read another thread where they were talking about a limit switch? Is that something that would allow me to be getting motor sounds like it's trying to go up, but no actual action at the motor? Thanks,
