Trim & Tilt Switchs do NOT work

[rfdfirecaptain]

I have a 1993 Crownline 250CR with a Volvo 740 powerhead and DP-D1 outdrive. The boat is outfitted with a separate TRIM and TILT switch on the throttle handle. Both switchs are dead except for the TRIM down position. That is the ONLY position that engages the hydraulic pump. However, when the TRIM up is engaged a relay behind the dash panel clicks. The trim indicator is working propely according to the trim gauge on the dash panel.

I have hotwired the Green and Blue wires from the hydraulic pump and I was able to raise and lower the outdrive without any problems. It's somewhat difficult to see the hydraulic pump behind the powerhead, but there appears to be 2 relays for it on an attached bracket. Additionally there are 2 more relays behind the dash panel near the throttle handle (1 of those is the one that clicks).

I'm getting married on Saturday July 11th, and we had planned to do about 350 miles on the ICW to Charleston and back. I haven't used the boat this year at all and I just found the problem this past weekend in my pre-trip inspection and I'm all out of ideas Obviously this could change the honeymoon plans if it's not corrected immediately. Any and all ideas are appreciated.

Re: Trim & Tilt Switchs do NOT work

Mmmmmm?? Very few views and no responses means the honeymoon plans aren't LQQKing too good!

OK, so on another note, does anyone have a place at the beach or mountains that's less than 300 miles from Raleigh, NC?

MORE INFORMATION:
My batteries are less than 6 months old, and reading a steady 13.3 volts. I've disconnected the Green and Blue wire harness at the hydraulic pump. As before, when the TRIM DOWN switch is depressed I have power on the green wire but there is no power when the TRIM UP switch is depressed. And the TILT switch clicks a relay in the dash panel whenever the switch is depressed in either direction, but does not read any power on either the green wire. Also, I have rearranged the relays to see if I could move the problem around. That didn't make any difference. The hydraulic pump still works in the TRIM DOWN poistion Only. The only reason I have not replaced the relays is becasue other iboat forums state it is unlikely that they are bad.

Well, I'm going back out into the hot sun to see if I can work up a miracle. I'll keep checking for your replies about every hour.

Thanks!
Keith

Will it go up with the trailer button?


Do volvos have those?

Re: Trim & Tilt Switchs do NOT work

Thanks for your reply and sorry if I wasn't clear enough. It will NOT move upward at all using either the TRIM or TILT buttons.

Re: Trim & Tilt Switchs do NOT work

I would make sure you have continuity between the pump and the switch, and if there is a relay, ensure there is continuity on each side. If there is check the voltage, and lastly replace relay.
just guessing this one

ROb, thanks for your reply. OK, I'm a professional firefighter (the guy people call at 3 am for their problems) I have a lot of knowledge and tools, but no real expertise with this kind of stuff.

My question to you is continuity on the relay would only occur when the contacts are closed right? Is there a proper way to test a relay for continuity?

Thanks!
Keith

Re: Trim & Tilt Switchs do NOT work

do you have a multimeter with a setting that when you touch the ends of the probes together it buzzes, whistles, screams, you get the picture.
thats the continuity setting it just shows you that you have a complete circuit. As you may have to take a piece of wire and jummper the two wires together MAKE SURE YOUR MAIN POWERS OFF AND THE TRIM MOTOR IS DISCONNECTED. we dont want any sparks flying.
if your multi meter does not have this option use the ohms setting 0# ohms when the probes are touching is good as there is no resistance, a high number or a blank screen shows high resistance or no continuity.
traceing faults down realy sucks.

relays require power to pull the contacts together if you here it chatter I bet its gone

Re: Trim & Tilt Switchs do NOT work

Yes, I have a meter with the continuity buzzer. It's getting dark here now, but I'll try it first thing in the morning and report what I found... around 8 EST. SO, just to clarify.... does the relay need to be powered up in order to get continuity on the other leads?

Re: Trim & Tilt Switchs do NOT work

honestly keith I cant remember, damm bald timers anyway.
BUT I can send you into the adults only stickeys, were there should be a section on your leg/pump, that will include the factory diagnostic section that should walk you through the steps A-Z.
let us know how you made out

Re: Trim & Tilt Switchs do NOT work

Ok just showered ate a late dinner. Now I feel refreshed and becasue I'm in such a time squeeze I think I'll go pull all those relays and se if I can get continuity. I'll report back tonight.

Re: Trim & Tilt Switchs do NOT work

I Just checked t 2 relays on the power trim hydraulic pump and the 2 behind the dash panel. If I tested correctly they are working fine.

I applied 12v power and I could hear the contacts close, plus I used my buzzing meter to confirm continuity.

Well, it's after 10PM here now, so tomorrow morning I'll see if any west coasters pick up on this thread and offer any more help.

Thanks!

Re: Trim & Tilt Switchs do NOT work

hey there keith-
how you makin out, did you look for the stickeys with your leg and trim pump.
it is 7.15 pst here, and I will stick around awhile if you want some help. drop me a pm

Re: Trim & Tilt Switchs do NOT work

HEY BRAIN STORM-
just re read your first thread and you said that you jumpered the two wires that plug into the two wires that go to the limiter switch and you have both up and down, if this is the case I think it is either the wires going to your limiter switch or the bloody switch itself.
if thats the case, jumper the wires, get married, have fun deal with it when you get back, just pay attention when you trim up.

Re: Trim & Tilt Switchs do NOT work

If you have solid wiring and you know the relays are working, then the TRIM and TILT switch on the throttle handle is worn out.

I bought my 83 Four Winns and it had a new separate basic toggle switch installed to control the trim because the hammer switch or Trailer switch had worn out. Its just mounted on a metal peice like a 2 inch ruler right under the hammer.

A few years later the trim quit working and it turned out to be the solenoids on the hydraulic pump. I think mine clicked to when I checked them but one was still bad.

In your case you have 1 function of 4 working - Right? So maybe 3/4 of the trim handle switches died, rather then 3 of 4 solenoids.

Did they all die at once? Over the winter?
If you are in a pinch and can hot wire it - you could wire some toggles temporarily near the pump - rulers are cheap.
