Tilt and Trim Inop 200 Johnson

[Knockerjoe]

I just pulled into my slip and my 1994 Johnson 200hp ocean pro will not trim up or down. I checked tnt fuse was ok. both relays are clicking but i do not here motor running. Any ides where to look next when i check it in the morning? thanks in advance....joe

Pull the wire connector apart coming out of the relay box. Make sure there isn't any visable corrosion-clean if there is- apply some die-electric compound (electrical grease) and reinstall.<br />If that doesn't do it, with plug disconnected, test voltage at the 2 wires coming out of the relay box-should be a blue and a green. Test from one wire to ground and have someone run the trim switch. You should have voltage at both, one in up (blue) one in down (green).<br />I'm guessing however, you have a bad connection, which is not uncommon and should be easy to find.

I agree with walleyehed, it is probably a bad/corroded connection. I have experienced this situation, but usually the engine will just go one way but not the other. I take the relays out of the connection buss and clean all the contacts. Look for other corroded connections on the buss as well as the buss sockets. I assume you get the same results from both the throttle and engine switches.<br /> However, if the motor is getting power, the motor itself may be bad/grounding.That should be easy to check also.<br /><br />Good luck!<br /><br />Dave K.

Update: pulled relays and saw no signs of corrosion, sprayed with contact cleaner. Tested voltage at relays. checks good when i hit the up /down switch and i get my 12 volts both ways. Should i check the wires going to the motor next? is there a plug? where is it located. thanks again. joe

Re: Tilt and Trim Inop 200 Johnson

You now have to check if power is being supplied to the motor. I have not ever had to go that far.But, I would trace and inspect the wires from the trim motor to the relay buss.Ther may be a connector between the relay buss and the motor as I would not expect that the motor was originally supplied with wires long enough to go from the motor to the buss, but I could be wrong.If there is a connector..that could be a trouble spot in the wireing. I hope it is not your motor..that one is a tought one to fix according to my brother .<br /> Did the TNT work all the rest of your day on the water?<br /><br />Regards, <br />Dave K.

Note: the TNT motor was replaced about a year and a half ago. There are butt splices connecting the new motor to the old wires. The problem is that the motor is now stuck in the down position and my boat is in the water so i am going to have to somehow open the valve and push the motor up at low tide and check that those splices did not crack or corrode. thanks for the suggestions so far.

Re: Tilt and Trim Inop 200 Johnson

If you checked in the correct location for power out, up and down...that IS the power supply to the motor.<br />You say you have splices..that would be the next obvious test point. If you still get voltage there, it sounds like a motor.<br />Usually when it just "quits" in both directions,9 out of 9 times, it's connections...<br />I suppose it could be the tilt motor, but make sure of the splices first.

Re: Tilt and Trim Inop 200 Johnson

Hey Joe,<br />I just fought a butt splice problem yesterday on my bilge pump float switch system.. the wires were butt spliced and of course the wires are bare from the splice end to the start of the wire insulation. They corroded at that point,broke loose, pump stopped. the original installer did not take pains to protect that part of the splice. So, as mentioned by Kenny, that could be the flaw. I have replaced all the butt splices in my boat by soldering the wires and then covering them with the liquid applied coating. Did you look at the splices when they were made? <br /><br />You are getting close to the problem.<br /><br />Dave K.

Re: Tilt and Trim Inop 200 Johnson

Ok, i got out to the boat this morning. The wires and splices going to the trim motor looked good. I cut the wires at the splices to check the voltage going to the motor. Voltage checked good at 12.4 volts at up and down. ****! Now im thinking bad trim motor. I was ready to give up when i decided to remove the black tubing that was covering 6 inches of the trim motor wires. I found a kink in one wire which got pinched and salt water got in corroded and was hanging by a thread, thus allowing the 12.4 volts to go through but not allowing enough voltage to operate the motor. So I put new splices on and i am good to go. I want to thank everyone for their help and suggestions.......joe

Good job trouble shooting the problem...<br />As I said, it's usually something simple, just follow downstream until ya find it!
