I have another thread about heat alarms and I'm working on that but I now have an additional problem. as the title says, trim goes down but not up. I got the thermostats and water pump kit from Bill's on Friday. Saturday morn I installed the thermostat parts. Then I started on the water pump. I had trouble finding the linkage screw. In the search I ran the motor up and down a few times and left the motor all the way down. The manual didn't say where the screw was and I didn't see it. Did some internet research and realized the screw is on the left side not on the right where the cables are and the midsection covers needed to come off. In preparation for the removal I went to tilt the motor up and got nothing when I pressed the switch on the motor to go up. The tilt motor would run if I pressed down. I tried the switch on the throttle and the same, nothing up but the tilt motor ran on the down side. I have tried the tests in the manual to check the relay and it checked good. After trying a few other things I even changed the relay and situation is the same. The relay has two plugs. A large and a small. There is a test for the large and I'm getting the correct voltage there. The manual says it may be the manual release manifold. But, The small plug has two pins. If I use a jumper wire and energize those pins the motor goes up and down like it should. I attached a picture of the plug to avoid confusion in case I am not explaining this properly. So it seems to me that this should be a switch problem but neither the throttle switch or the switch on the motor will work the up function. I have not found a test for the switches in the manual. So are the switches connected somehow? Or does my jump test not prove anything.   I don't see anything around the thermostats that I may have dislodged.

WO, I am not sure if you can switch (invert) the wire on the "switch" to se it if the problem reverses, it sounds since  you switch the relays that is not the problem it has to be switch related

Maybe you have a bad tilt limit switch.

The trim switch on the cowl has 3 wires, red is power, it puts power out on the green wire to the plug you are testing for down trim. It out power out on the blue wire to the tilt limit switch, located on the motor tilt pivot shaft, then to the plug you are testing.

I was too irritated last night to do any searching. But I now see a few threads on here about this. It seems that the most likely culprit is the tilt limit switch. I've bypassed the cowl switch with a jumper to verify that it isn't the switch on the cowl. So the suggestions above seem to be the next move. Thanks for the input.

I have tried bypassing the tilt limiting switch with a jumper wire. Blue wire with white stripe on both sides of plug. (see picture). still the same situation, I have down but nothing on the up side. It goes up and down if I jump the pins as described in my first post. The manual suggests changing the manual release manifold but I just don't see how that could be related. ??? I have the feeling it is something simple or I am doing something stupid but I am out of ideas. Can any of you think of where
I have gone wrong?
I just realized I didn't list the motor info. In case it makes a difference it is.....

well this is solved. eventually the problem was the tilt limiter and cutting off the plug and joining the wires with a butt connector got the up tilt working. The complication was that the first thing I did was change the relay. When that had no effect I kept looking. Yesterday I used a jumper to bypass the tilt limit switch and that had no effect on the problem But today I found that the up wire in the new relay was not crimped into the plug. So that kept the jumper wire from working. If it had been any other wire I would have found it much sooner but it just seemed to be a continuation of the original problem. So I put the old relay back on and all is well.

Yay!  Thanks for the update.

Just for reference, was that an OEM relay, or an aftermarket?  Sounds a bit weird that the wire wasn't well crimped.

Best,

Phil

Phil,  I always try to finish the threads I start if I can. It always bugs me when threads are abandoned without posting the outcome. As for the relay; I am pretty sure this is not a E part. This was  a Saturday morning Buy/Borrow affair from a local independent outboard mechanic and I really wanted to change the water pump. So I wasn't choosy. The box doesn't say Evinrude and the part doesn't
have the E part number stamped on it like my original.  So good call on your part to ask and lesson learned on my part.
