Trim and Tilt issues

[rwcrazy]

ok I have a 1978 85hp Evinrude, the trim and tilt worked fine, and one day it stopped, I replaced the solenoid but it still doesnt work
It has a jimper block on it with the green and blue there, if i jumper from the red to the blue or green it will go up and down.
any way to check the switch?
Or do you think the jumper block it bad?
I think it is just a peice of metal that transefers the juice??
Help
Thanks

Re: Trim and Tilt issues

If you can jump it at least you know your trim motor is good. I assume you checked the inline 20 amp fuse right?

Re: Trim and Tilt issues

I connected a ohm tester on it and it seems to be good, I also disconnected the wire with the fuse off the jumper block and touched the blue and greens wires and the trim/tilt worked
any help would be great thanks

Re: Trim and Tilt issues

If you have a new solenoid, are getting power there, you know the trim motor works since will engage when you jump the posts, the inline fuse is good, maybe try cleaning the connections inside the box with contact cleaner.

Re: Trim and Tilt issues

does that jumper block do anything, besides just transfer the power according to the switch?
Thanks

Re: Trim and Tilt issues

on the switch should I have any power?
if I push the up, should the blue have power and push down the green should have power?
Thanks a bunch

74 Evinrude Trim and Tilt issues, HELP!!!!

74 Evinrude Trim and Tilt issues, HELP!!!!

I am looking at the image above
Ok, I took the block,(where E1, E3, ground etc,) are at, all apart, cleaned all the wires and the bock, and it sill is not working. If I take a pair of pilers and touch E-1,(red) to E-6, (blue) or E-1, (red) to E-3, (green) the trim will go up or down.
I Disconnected the connector and put my tester on there and the red, I dont get any power at the connector, nothing at the switch either.

I have replaced the solnoid, so that is new, I also put the old one back on just to see if the new one was a problem and still nothing?
Help, I wanna go boating..

Sorry it is a 78, not 74..

Re: Trim and Tilt issues

First check the manual release valve. Rest motor on locks and check oil resevoir level. I will show you how to trouble shoot the electrical system below, with help from the nifty chart ezeke supplied, it will help in this. It took me a long time to type, so i hope it helps, lol.

1. Make sure battery is FULLY charged.

2. With a voltmeter, connect red lead to point E1 in junction box and meter black lead to point G. Meter should indicate battery voltage.

3. If no voltage is indicated, move meter red lead to poiint E2 on solenoid. If battery voltage is indicated check FUSE in junction box. If no voltage, check red and black leads to battery for poor connection or open circuit. Polish them up, no corrosion, dirt, rust, etc...

DOWN CIRCUIT

1. Move red meter lead to point E3 in junction box, push trim switch in the down position. Battery voltage should be indicated. If trim motor does not run, test motor.

2. If no voltage is indicated at point E3, move meter red lead to trim switch at point E4 and meter black lead to point G1. Push trim switch in down position. If meter indicates battery voltage, lead is open between point E3 and E4.

3. If no voltage at point E4, move meter red lead to point E5 in trim switch. If battery voltage is indicated, trim switch may be defective.

4. If no voltage is indicated at point E5, check continuity of ground lead from trim gauge G1 to junction box point G. If ground lead is good, move meter red lead to junction box at point E1 and meter black lead to point G on junction box. If battery voltage is indicated, lead is open between E1 and E5.

UP CIRCUIT

1. Connect voltmeter red lead to junction box at point E6 and meter black lead to ground at point G. Push trim switch up. Battery voltage should be indicated. If trim motor does not run, test motor.

2. If no voltage is indicated at point E6, move meter red lead to point E7 on solenoid. Push trim switch in up position. If voltage is indicated, blue lead is open between E6 and E7.

3. If no voltage is indicated at E7, move meter red lead to point E8. Push trim switch in up position. Battery voltage should be indicated. If trim motor does not run, connect meter red lead to point E2 on solenoid. If battery voltage id indicated, solenoid is DEFECTIVE and must be replaced.

4. If no voltage is indicated at point E8 on solenoid, move meter red lead to point E9 and meter black lead to ground at point G1 on trim gauge. Push trim switch in up position. Battery voltage should be indicated. If battery voltage is indicated, lead is open between E8 and E9.

5. If no voltage is indicated at E9, move meter red lead to point E5 on trim switch. If voltage is indicated, switch is defective and must be replaced.

6. If no voltage is indicated at E5, check continuity of ground lead between trim gauge G1 to G in junction box for open circuit.

7. If ground lead is good and no voltage at E5, move meter red lead to E1 in junction box. If voltage is indicated, lead is open between E5 and E1.

TRIM INDICATOR CIRCUIT

1. Connect voltmeter ted lead to point E10 on indicator gauge and black lead to G1 on indicator gauge. If battery voltage is indicated, proceed to step 4.

2. If no voltage indicated at E10, move meter red lead to horn at point E11. Battery voltage indicated lead is open between horn and trim indicator gauge.

3. If no voltage, move meter red lead to point E12 on key switch. Battery voltage should indicate. If no, check key switch. If key switch good, check engine fuse and lead to key switch for open circuit.

4. Disconnect tan/white lead from "S" terminal of trim gauge. Connect ohmmeter to disconnected lead "ohm1" and to G1.

With the motor in the full trim position, ohmmeter should read 82 to 88 ohms. With the motor in full tilt, ohmmeter should read 0 to 10 ohms. If infinite reading check for open circuit between trim gauge "G" terminal and "G" in junction box. Also check for open circuit in tan/white lead with lead disconnected from "S" gauge terminal. Check between "ohm 1" and point "ohm 2" in junction box. Disconnect both black sending unit leads from "ohm2" and "G" terminals. Check for above resistance readings. If not within specs, replace sending unit.

Re: Trim and Tilt issues

I think it was a little low, and i had put more oil in. Where is the manual release?

I will also go throught the list,
Thanks

Re: Trim and Tilt issues

No problem at all. The manual release valve will look like a screw with a slot in it and a snap ring on it on the starboard side of the unit right above the bracket and below the resevoir. Cycle the motor a few times too when filling, then re fill. I know the list is long, but thorough and should help you nail down your problem. It looks longer than it is, you'll fly through it in no time. Hope you're boating soon, gl

Re: Trim and Tilt issues

Ok thanks for all the help, I had 2 issues..
1, the red from E-1 to the switch, the wire was broken, spliced the wire together,

2, the new solnoid was bad or incorrect, it would go down but not up, so I, (just by luck did not toss the old one out), put it back on and everythign works great..
Thanks for all your help, I owe ya one.

Re: Trim and Tilt issues

That broken red on E1 would of been your original prob, Glad i could help
