Baja NO Trim!! NO Power @ Solenoids

[tank1949]

Go back and clean all electrical lugs, especially if salt water boat. I had master circuit breaker go weak or defective on one motor side. It cause starter to delay or drag and ate up flywheel gear.

I will try again in morning. Didnt think to test the hot lead after the 110 amp fuse. Just went straight from battery to fuse.

 

[Rose88]

Ok checked voltage and as long as I'm running hot wire from battery to solenoid 110 amp fuse I have 12v coming thru it. Still only works down only. .01-.02 ohm's to blue white wire.
hooked it back up to starter fuse wire and back to nothing

 

[Rose88]

Is there anything between the starter 90 amp fuse and other side on input @ the 110 amp fuse? Have power at starter and fuse leaving it, but nothing at the input side where + wire comes into the solenoid 110 amp fuse. Where are the relays located? still doesn't tell me why theres no power from 90 amp to 110 amp on the red wire

Ok, now it works only down no up

Keep it wired like that. Swap the blue and green wire and see if it goes up.

 

[Rose88]

I swapped the big blue and green on solenoids and pushing the down button it goes up now.

Well there you have it. See if you have 12 volts on the blue wire when you hit the switch, probably not, So it's a broken wire or a bad trim switch

Ok I will check that, but why am I not getting power from starter to solenoids? Right now I am coming off batt straight to solenoids.

Little lost here, where on the blue wire at solenoids? Little blue or big blue?

see post 2,
you need 12 volts at the main buss bar that goes between the solenoids From that buss bar is a small red wire that goes to the fuse in the black rubber casing. That supplies power to the switch in the control handle to energize the small blue and green wires on the solenoid.
The large Blue and Green are the motor wires you can test the motor operation by jumping from the battery to them.
Next touch the small lugs on the solenoids, blue goes up, green goes down.
If the solenoids operate the motor , but the button on the handle dosent, you have a broken wire in the harness someplace
Test from the back side of the 110 fuse and then from the front side. It should operate the solenoids . If it only operates in 1 side the fuse link is blown.
Most trim pumps are direct to the battery or direct to the starters main large lug, NOT to the 90A fuse link.

Ok both of my trim switches show 12v at switches and all way back to harness at solenoid area. Then looks like they go to a dead end and capped off ?? Kind of like a relay box but without the relay.

I have power at 20 amp fuse both sides, power to both solenoids, the wire that comes from the starter fuse on motor...does it have any other wires with it to make this work? or just the hot cable to the 110 amp fuse? My trim switch on the gear stick is little wires that go to another dash mounted switch in which it's confusing because the down wire is green to blue and blue to green, however once they go into the bigger dash switch they get heavier and my blue goes to purple all way back to harness beside the solenoids.

Thinking about running long jumper wires over top of seats just to try something to see if it will work.

really need to see some pics.of this extra box

 

[Rose88]

Also when I turn on the main batt switch theres 1 ACC switch that the light comes on when its not on?

I have never seen a starter that wasn't direct wired from battery selector. The solenoid power may come from main or dedicated breaker. But, my boats may be outdated. Good luck!

 

[Rose88]

This one is wired from master switch to the starter, but once the power leaves the starter via 90 amp fuse or breaker looking relay it goes across to Supply 12v to solenoid buss bar. I have no 12v at the solenoid bar, so I ran another wire from batteries on that side to solenoid and now have 12v. I'm thinking a wire broke on the up switches. I will know tomorrow km running 2 new wires as jumpers to see.

 

[Rose88]

Ok, if I run a jumper wire from little blue post to switch it works, I have 12v to switches but my blue wire leaving switches going to solenoids turns into a purple?? Both work if I run a jumper but can only jump 1 switch at a time. Trailer switch is not working unless you are pressing trim also. I'm thinking there's no hot to the trailer switch until you press switch. Pics coming

Notice the purple wire also feeds the trailer switch only when the trim switch is activated

This is how the trim system works.

There are small Blue/White and Green/White which come from the trim switches that energize the relays.

There are larger Blue/White and Green/White which come from the main post on the relays to the motor

Trim switches
Red is main power which goes to the center contact of the up/down switch (STDT)
Blue/White and Green/White small wires come off either side of the trim switch which has Red in the center
The Green/White goes straight to the bottom relay at the trim motor
The Blue/White goes to the trim limit and then to the top relay at the trim motor
The Red wire also has a jumper which connects to the Trailer switch
The Trailer switch has a Purple/White that connects to the Blue/White in the harness at the trim limit (this is used to bypass the trim limit)

Which side is the trim limit switch located? That may be where problem is.

Limit is on port side

Monster power lead (may be 2/0) cable from battery selector to starter. Direct hot lead from starter (same lug from battery selector) to trim pump, yes. The pump's solenoid voltage is fed from helm power.
