Trim Wiring....

[HighTrim]

Happy long weekend guys....

You've all helped me get my motor running strong now i just have a couple of wiring questions for you, I wish i didnt have to bother anyone but my manual is not yet here and believe me i search the posts for hours but cannot seem to find my answer. I have a 1978 Chaparral Bowrider with a 1976 200 hp Johnson Seahorse V6. My question is the wiring coming from the trim buttons on the side of my throttle control are cut about 3 ' back so im not sure where i run them to, i currently have no control over my trim tilt of the motor. I also have no gauges working at all in the dash. There is a large group of wires coming from the back relay/battery area that are unaccounted for. It has a group of blue, green, red, white and black wires in it, could these control the dash gauges? The wires coming from the trim contols are white, green and black, do these run to the trim motor somewhere? Any help you guys could give will definately save me some time tinkering.

Ty all and have a fun boating long weekend, wish i were out there to join u!!

Re: Trim Wiring....

The 1976 model incorporated one large solenoid for the up mode and direct wiring for the down mode. Is this what you have OR has that unit been converted to the dual relay setup.

The dual relay setup would have a small black plastic rectangular box that contains two (2) small relays and a wiring terminal of sorts.

Which do you have?

Re: Trim Wiring....

Joe is this the box that you're talking about, it's right near the battery with a pos and neg that run to the battery, then the large wire that i was talking about running up front and it has a screw down top on it. Sorry this site wont let me upload the pic i just took, i think its too big. But the little plastic box has a 2 amp fuse in it, a large red and black wires running to a round metal cylinder of some kind, and then a bunch of little wires on terminals. Is this what you mean? If so , then yes i have a dual relay setup. Would i just connect the wires coming from this box to my wire coming from the trim controls?

Re: Trim Wiring....

Ok I traced the wires coming from the trim motor and they definately go to that plastic box. Now the colours of wires coming out of the box towards the front of the boat and the colours of the wires coming out of the trim controls on the throttle match up, but the size (gauge) is larger on the ones coming out of the dual relay setup, will this matter at all? There will also be 2 wires left over out of the group of wires coming from the relay, a red and blue, where will these go? Ty all.

Re: Trim Wiring....

I've been tinkering with that little box all week, cleaning out oxidation from the terminals. I'm not 100% certain, as I'm at work and can't just run to the garage and check, but I'm pretty sure the wires running to my box are a smaller guage than the the ones in the bird's nest of wires in the box.

Two bonus wires doesn't sound very good though. It seems to me that every wire should have a home. Note by my whopping 3 count of posts that I'm no expert however.

Re: Trim Wiring....

That sound more like the single solenoid setup to me when you speak of, and I quote "a round metal cylinder of some kind". That's one (1) metal cylinder which is most likely a solenoid. The relay setup would have two small square components (relays) within the box on each side. See the following for the solenoid setup.

Re: Trim Wiring....

ty both for your posts. I believe you may be right Joe, i inspected the box again and i do believe its a solenoid. I dont want you to think that im doubting your diagram, but rather im confused about it. I have a few "groups" of wires coming from my solenoid box. 1 goes to the trim motor, 1 goes to the battery(a positive and negative wire in the insulation) and 1 is about 20 feet long that is just cut off, this is the one that i cant figure out how to hook up. Within it it has 2 small wires, a white and a black, and then 3 larger guage wires, a blue, red and green. where could this set of wires possible run to, since theyre all insulated together, im assuming they run to the same place, but according to your diagram they should all run seperate ways. Im sorry to be a pain, but it is starting to frustrate me and i dont really want to hit the water without trim control, lol. Ty and Ty

Re: Trim Wiring....

Does anyone know if not my answer, any other avenues i can try b4 i have to pay for a mechanic to wire it for me, ty chris

Re: Trim Wiring....

ok well ty all anyways, ill try to get to a mechanics in the morning and let u all know how to fix it. Happy boating

Re: Trim Wiring....

The diagram is the answer, it's called a schematic. The wires do not run to seperate places BUT in a schematic one does not actually picture the wires as you actually see them.

Example... Battery ground, solenoid ground, electric motor ground are wires that lead to the negative ground post of the battery at one point or another. The Black wire, Blue wire, and Green wire are all leading to the electric motor. The long 20' cable you mention is more than likely the cable leading from the solenoid and the electric motor to the PTT switch.

It appears that you're letting the remains of the actual wiring that you have there confuse you with how you're interpreting the diagram.

Re: Trim Wiring....

ty Joe for your help, i really do appreciate it. Ill try connecting the long wire from the box to the PTT switch today, i was just worried about the size differences, they just didnt look like they should match up, and the fact that there were 2 extra wires leftover. Have a good weekend all.

Re: Trim Wiring....

Good News,

Thanks to much help, I think i have finally got all my wiring sorted out. The gauges on the dash all seem to work, as well as the cd player, lights etc....
my tilt trim is almost there. The extra 2 wires that i was worried about ended up being for the tilt trim guage, but i dont have one. My only problem now is when i activate the trim,the solenoid makes a clicking noise and I blow the 2 amp fuse at the relay solenoid. Could I possibly need a larger fuse than 2 amps? OR could i be popping fuses because the solenoid itself is no good. Will that solenoid be easy to find, even though this is an older motor? Ty all for your help

Re: Trim Motor Test?

Hey guys,

Ive got my trim motor all wired up properly now but im getting a clicking noise at the solenoid and no movement out of the motor. I then tried crossing the posts of the solenoid with booster cables to raise the motor but still nothing. Should i tell myself the bad news that my trim motor is shot? lol If so, where would i go about finding one? Can you get them used and if so where? Hard install? ty all
