Tilt/Trim problem

[emtmedic99]

I have a general question and hope you can help. I have a 70hp Evinrude. It is on a 89 Tracker boat. I took the boat out of winter storage. I raised the motor to install the transom saver, after I raised it up and went to lower it back down, nothing happened. It wont go up or down. I have checked everything I know to check. I have power everywhere but still can't get the motor to move. When you push the up or down button from the motor or from the throttle, I get a click when I try to go up and a buzz when I go down.I pulled the relays out and swapped them. Same thing. I used a test probe and I have power through the switches, relays, power harness all the way to the pump motor. It is full of fluid. I can do a manual release and it will go down. My question is this...Is this a problem with the motor or could it be something else. It seems is tho the motor is froze or bad, but I am not real sure how to determine if the motor is bad. The model # on the motor is TE70TLCEM.

Re: Tilt/Trim problem

Emtmedic99.... Your description of the noises you hear would indicate that there is either a loose or dirty connection somewhere which would result in a voltage drop. To check the electric motor, trace the wire from it back to a connector, then disconnect the connector. Apply battery voltage directly to the motror wires. Depending on which way you hooked up the wires, the motor will run one way or the other (dual polarity elec motor).

Re: Tilt/Trim problem

I will give that a try. The noise I am hearing is in the relays. I forget to mention that.

Re: Tilt/Trim problem

If your T/T motor checks out by hooking it up direct consider looking into the tilt limit switch for your problem.It's located near the tilt bushings ,starboard side.

Re: Tilt/Trim problem

Check your battery for charge and make sure the terminals are clean, after sitting all winter, they may have gotten a litte corrosion under them.

Re: Tilt/Trim problem

The batteries are fully charged. I am interested to know where that switch is. I looked around and am not sure what switch you are referring to. I am not a boating guru, but from other conversation I assume the starboard side is the right side looking at the motor from the back.)drivers side).The motor will start so I know we are getting power to the starting part of the motor.

Re: Tilt/Trim problem

The tilt limit switch should be located in the area mentioned .It is situated around the steering rod tube that is between the tilt bushings.It prevents motor from being tilted too far and contacting the boat causing damage.

Re: Tilt/Trim problem

Check the fluid level. Sounds to me like you might have the motor as far up as it goes and not enough fluid to operate the T&T to take it back down.

Re: Tilt/Trim problem

Question, do both relays have the same part number? If you have access to a digital volt meter check your battery voltage and make a note of it, then with the T/T motor connected to the harness check the voltage at the closest connections to the T/T motor as you try to activate it in both directions and write this down, and lastly assuming the cable to the T/T motor has two wires disconnect the motor from the cable and check the resistance across the cable connected to the motor and let us know what you find. The resistance across the motor cable should be very low, almost the same as when you connect the two test leads together.

To Joe Reeves,OMC Guru,Member # 6826. I tried what you said. I traced the motor connector bach and unhooked it. I then took a jumper from the battery and applied it to one of the leads, nothing happened, I then tried the other lead, still nothing. I left it hooked up and got my test light out. Here is what I find interesting. No matter which lead I hook power to, when I check power with my test light, it shows power on both leads. I am not familiar with that motor, but I would assume that there should only be power on 1 lead to the motor. Sounds like that motor may have a dead short on it.

Re: Tilt/Trim problem

Eemtmedic99..... Hooking up the voltage to only one PTT electric motor wire will do nothing. The motor is a dual polarity motor, meaning that hooking up BOTH battery jumper wires (positive & negative) to the two wires leading to the motor will make it run in one direction, reversing the wires will make the motor run in the opposite direction.<br /><br />The circuitry of a dual polarity elec motor would make one think that there was a short within it when testing if one did not understand the circuitry.<br /><br />The 1989 70hp PTT does not incorporate a tilt limit switch.

Re: Tilt/Trim problem

Joe, Thanks for the info. I will try again in the morning and let you know.

Re: Tilt/Trim problem

To Joe Reeves,OMC Guru,Member # 6826. I hooked that up the way you said and it works, switching the wires makes it go up or down. I put it back together and disconnected the switch. Jumped across the leads and still nothing. Switched the relays and nothing. My question is it possible that both the relays are bad. I have checked everything, all the connections, all the wiring. Everything seems ok. I am just not sure where to go from here.

Re: Tilt/Trim problem

Joe you seem to have a pretty good knowledge of trim and tilt. I have a 89 90hp Evinrude been working fine up till Sat. Went out and came back in used the trim several times. got back to the ramp no trim or tilt. When I push the switch on the console I here a click on the back side of the engine but nothing else. All help appreciated.

Re: Tilt/Trim problem

Emtmedic99.... You could purchase one relay to use as a test equipment item, then switch that new relay from one plug to the other. If doing that makes the unit operate, obviously you've got two faulty relays.<br /><br />However, I've never seen two relays go bad all at once..... but it's a good idea to have a spare relay on hand for emergencies anyway, and the relay test will eliminate any questions in that department.<br /><br />Since the electric motor is okay, the problem obviously is with either the switch or the wiring associated with the PTT relay/junction box. You're simply need to look those items over closely...... loose, corroded wiring etc. I wish I could be of more help but without actually being there, I can't think of anything else.<br />----------<br />Steve..... Your problem would ride side by side with Emtmedic99's as above. Follow those posts and let us know what happens. I'd suggest that you start your own topic to keep things seperated though.

Re: Tilt/Trim problem

Joe...Well I dont think it is the switch, it wont work from the throttle or the motor. I disconnected the switch and just jumped the wires. Still nothing. The curious part to me is that switching the relays has no effect, 1 clicks the other buzzes. I disconnected the wiring that appears to go the throttle handle. Still same thing. The relay junction box is really hard to get to. I tried to get it out but it is in there well. I will try again later. It is a new week and have to get back to work, will try if I have time after work. If nothing else I guess it will be down to tracing it, wire by wire. Is there a known good source for wiring diagrams. I am still searching for an owners manual. The person I bought it from doesn't have it. I will keep you updated on the progress.

Re: Tilt/Trim problem

UPDATE Thanks Joe I simple pulled the connector apart on the back side of the relays put a volt meeter on it pushed the switch bingo 12 volts. Now I know the problem is past the relays and the only thing left is the motor itself. Good new bad news. I tapped on the motor with a broom handle and it now works fine.(good news) Problem is now I don't trust it and does the motor have water in it and will go out next time in the water.(bad news) price for the rebuilt motor looks to be about $179.00. Joe what you think?
