tilt/trim

[porkys2024]

can you help me figure out my wiring harness prob. I have a 1999 fisher 25 ft pontoon with a diff, newer model engine a 2004, 3.0 mercruiser stern drive with what looks like a 9 pin harness, lot of the engine compartment harness has been cut and cobbled and somewhat diff color wires attached. the block number is 1M12054RP and i think it is OLO97000 THRU OW301999, Eng ser number is OW 001-466.. they are 8 pins in the male plug but 9 holes one looks missing, Blu, Red, Grey, Black, Brown/white stripe, Tan/Red stripe, tan and purple but i counted around 20 wires running up to dash board. side note, the female connector on harness has light blue wire and male has darker blue wire other then that all the same? I hope you can steer me in right direction. now what im needing is help with the trim sending unit on starboard side of stern and the tilt/trim gauge on the dash. ive done everything in the book to get it set right and working, now the port side puck for trim/limit works fine i have it set at 20 3/4 in rise.. but my gauge for tilt/trim can not get it to work.. its either up or down.. ive bought new gauge and pucks and still not workin.. I did take a the old gauge from dash and jumper-ed it to the two wires coming out of sending unit puck on side of stern unit and turned the shaft by hand and it works perfect up and down but put it back in gauge cluster and try it with the tilt/trim up down button on control lever and nothing!! im about to burn it! any suggestions? Thank you for your time. I do no that my book says the brown with white strip is the gauge sending wire and i have checked continuity between brown/w wire and its got continuity, if that helps and I assume the other is just ground? one last thing my unit works perfect both with just up and down button on the gear box also the trailer lift works as suppose to..

Welcome

Might try to use the return key once in a while to make it easier for us old guys to read

The gauge needs 3 connections to work.
12V to power it (comes from key, purple wire)
Ground Black wire
Sender Brown/White wire coming from puck

Puck 2 wires, one goes to ground and the other connects to Brown/White coming from gauge

How did you connect the 2 wires from the puck to the gauge?

one of the black puck wires went to brown/w wire going to back of gauge the other black puck wire to a ground.. as far as the back of gauge i do have ground going to the G, brown/w going to S, purple going to I and purple also (ignition) going to the light?

Sounds like there is a bad connection.
The Brn/Wht goes thru the 10 pin engine harness. You could run a jumper from the puck to the gauge to verify there is a bad connection

I did return/enter keys but i wrote it all out on word and coped and paste because i have it saved because of me sending it to others.. it and it all ran together.. sorry lol im pretty old myself 57 and about blind.. i understand..

if it ever stops raining long enough me to get it out so i can try I was going try that.... but i do no that brn/w wire is good because i have checked the continuity. I really have tried about everything... is there anything on the remote box that would cause it not to work?

You replaced the puck on starboard side and with wires connected it does not work.

Connecting gauge direct to puck it does work

There is a bad connection somewhere or your install method has an issue.

I connect wires to puck, turn key ON, go back to puck and slowly rotate it until I get a reading. Then adjust to correct position and install on gimbal ring

yes, u cant mess up hooking up two wires! one went to brn/w other to ground that much i know is hooked up right.. yes i went back and took off puck while still hooked up with key on and turned little center shaft on puck and gauge would go up and down accordingly its just when i install puck back into gimbal that it dont work on gauge when I use the remote button, but again the switch itself does raise and lower the stern drive. yes ive tried two new diff gauges and same thing happens..im pretty mech. inclined but i admit this has me pulling my hair and Im bald!

how about this!! I figured out the tilt/trim and fixed it how about on same boat the shift adjustments, mind you its a carb engine so I was told it was better to take of the shift assist off because it wasn't working right on it anyways and it was designed for carb engines.
i can either get it in reverse or forward but not both at same time .
it has to be adjusted for one or the other to work. new cable from trans and new cable to remote only, old cable is third one going to carb..
any suggestions, videos be real nice lol! oh this shift plate is also new. be mindful ive measured lash its in tolerance and lower cable measured 6 in center of barrel .

Clarify, you don't want to get it in forward and reverse at the same time

The shift assist can help but it was designed for any motor with a Alpha drive. Most people won't shift quick, they like to slowly shift and that is bad for an Alpha. The shift assist makes the shift quick

Look at 6th Vid down

noo how can i type this! if i adjust it to specs it will go into, lets say forward and locks but when i shift to reverse its between gears or not engaging at all! but if i re-adjust it to go into reverse and lock, it wont lock back in forward! also ive noticed my shift plate is upside down looking at other videos on here but thats the only way mine will mount.. bolt pattern that is..
does that matter? sometime also when shift into neutral the dogs r still trying to engage

Thanks,
In your pic the lower shift cable is on the bottom and the throttle cable is on top, correct??

 

[porkys2024]

top one g

top one goes to the lower unit! bottom to control box

Swap them

 

[porkys2024]

it c

Swap them

cant be swapt.. different barrels on them the brass barrel cant go on bottom.if u look closer at the pic u can see why. unless u r talking about the one going to carb. soon as daylight ill go check that never dawned on me because the throttle does work till u said this. I no it cant or wont be that simple though . lol

 

[alldodge]

Both those on the shift plate are for shifting, neither should go to the carb

I have three and it was on the right spot! got my hopes up for nothing.. I have three cables, one is the shift cable going to the lower unit and two coming from the control box to the shift plate! I guess one of the two from control works the throttle and one is for forward and reverse.
you said switch the two on shift plate but you cant they have two different styles of barrels.
im just missing something small in the adjustments.

how about this?
Ive got it going into reverse and neutral pretty good and almost into forward you can hear the dogs trying to in gauge but until i physically pull back on shift linkage it don't go in but the least bit of pressure from my hand on linkage then it will in gauge in forward..
is that normal at of water i know they talk about the water has to add some, hows is it put, pressure on drive for it to in gauge?
