Quicksilver trim fuse location

[ajochum]

I have an Alpha 1 350/260 with a trim problem. I couldn't get it to go down and after changing out the solenoid on the trim motor (one of two) - I realized that there are two canisters for the hydraulics. I filled the one with the two solenoids and by shorting the solenoids the trim works properly. However, I have no voltage at the shifter. I have lights and the boat starts. there must be a fuse somewhere but I can't find it. The red main breaker is fine and I have continuity on the square fuse & bridge on top of the motor containing the two solenoids. I unplugged the four wires that go from the shifter to the motor, cleaned contacts, etc. w/no success. Any ideas on where to look. Again, this appears to be a Quicksilver setup which I find little information on. Thanks.

I realized that there are two canisters for the hydraulics.

Huh,..??

and I have continuity on the square fuse & bridge on top of the motor containing the two solenoids.

Ayuh,... Continuity, but is there Power there,..??

If not, hook up the other end of the feed wire to the battery,...

Most definitely have 12v on both sides of the square fuse (?). Not sure on the bridge. By bridge I am referring to the 3/4" long connector near solenoids. Is this a fuse?

1 you must have 12v on the main buss between the solenoids
2 there is a fuse in a black bullet holder at the trim pump , its a red wire, it gets its power from the main buss bar and sends it to the helm switches.

Thank you Doc and Bondo - got to be hiding in plain sight. I looked all over and will probably go out on the dock tonight and find it. Am sure it is blown and it will solve the problem.

I worked on the boat today and my fuse was blown. Mine is a bit different - it is that white square one in the photo. I've just got to order it and I should be back in business. Thanks to all.

that is the 90A fuse link, very difficult to blow unless you short the main buss to ground ,so then what happened here

I had been trying to make the trim go down by going directly with a wire from the solenoid to the green wire below it. What I didn't know was that below the motor was a container that should have had oil in it. I have always only filled the one on the other side of the boat - didn't realize there were two. It groaned a bit and then suddenly nothing. Since then, I have filled up the container and was able to move the trim down by doing the above trick. However, I had no power to the front of the boat switch.
I am relying on the mechanic that happened to be on the dock today working on someone else's boat. He tested and found it blown. By the way - my system doesn't have that 20 amp inline fuse in it. The cover on mine says Quicksilver - think a bit different than the above pictures/diagram.

canister metal or plastic, dosent matter. pumps the same unless you have the older MC1 with 1 relay
the main 10Ga power wire has a 90A fuse link (the square plastic block) AND a 20a fuse inside a black bullet fuse holder. That is what supplies power to the handel , not the 90A one.
post a pic of the complete pump

Doc - I took these this afternoon. Tried to get all angles - most importantly for myself to then look and see just where this fuse is located. I have followed every wire and can not find one. Do you think this is the same trim motor/pump as the above drawing? Could it be another? Where else might the fuse be located?

 

[Bt Doctur]

this red wire must have 12v to operate the solenoids. someplace in there is a fuse or a resetting Cb to supply the power
the second arrow got lost but its the small rectangle block in the pic

Few more...

from what I do see the main connection to the 90A block the block goes to 1 solenoid with a jumper to the other solenoid. the other 2 posts of the solenoids take the blue and green motor wires.then there is a 3rd wire coming off the solenoid that looks like it goes to a re-setting circuit breaker , (the rectangle looking item with the 2 wires on it) and the other end of that goes to the red wire in the harness plug.

That rectangular item I have thought to be a fuse or bridge, but it has continuity going through it. From what you see, does it appear that this system may be a bit different and indeed the 90 amp (blown) just might send the power back to the trim up/down switch? I mean, I've searched and searched and can't find anything else other than these two items.

 

[Bt Doctur]

no, the 90A feed is connected to the solenoids and a 3rd wire goes to the rectangular resetting CB , continuity means nothing .
you need 12v on the red wire at the plug to operate the solenoids.

 

[ajochum]

OK - more checking tomorrow. Not going to order the 90A without further confirmation of it being bad.

 

[Bt Doctur]

do you have 12v at these green arrows ?

 

[ajochum]

Did the testing this afternoon. The only wire that has 12v is the main wire going to the 90 amp fuse. (top right arrow). The other three are zip. Thus, it certainly appears that the 90 amp is shot as everything flows from there.
