Hi all, :D <br /><br />Long time no post.... Good to be back again... :) <br /><br />Anyways, I took my deckboat out for a spin after sitting for a month or so. <br />The tilt/trim was sluggish going up/down then just stopped working. The relays were making the clicking sound. Tilt worked fine last time I had the boat in the water. :confused: <br /><br />As a solution I replaced the old wire running from the relays to the trim motor. I did have to splice and butt connect the wires. I used electrical grease in the connections, heat shrinked, then used the plastic paint on coating stuff to cover the heat shrink. I used 10 guage wire.<br />The old wires had been spliced and butt connected <br />3 times by the previous owner. I didnt like all the splices in the wires. :( <br />As a reminder, when I first bought the deckboat I had a tilt n trim problem and posted here for a fix. The great members here helped me and I traced the problem to a corroded wire at the trim motor. I spliced and butt connected that connection which solved the problem (2003 I think). Thinking a wire may be corroded again, I decided to replace both wires due to the several butt connections in line.<br /><br />THIS DIDNT FIX ANYTHING.... :mad: :mad: :mad: <br /><br />The relays still click.<br />I made a jumper wire and connected to fully charged battery. I jumped the green then the blue wire at the relay connector with the relays removed. It kinda moved for a second, made a humming kind of sound but no real movement. It started to move once then stopped. <br />The relay connectors were covered in the black/brown tarry stuff. Thinking good contact was not being made, I cleaned the connections of the socket and of the relays. This made no difference.<br />I checked the fluid level, it was full or nearly so, I topped it off anyways.<br /><br />I do not have a circuit tester and my digital electrical meter quit working. (sux to be me)<br /><br />I did a search here and read 15 pages of tilt n trim post.<br /><br />Whats next?, replace the relays at 15 bucks each ?<br /><br />I'm thinking I'll buy or borrow a circuit tester and see if juice is getting past the relays. <br /><br />If so, It looks like my problems may lie in the tilt/trim motor. A rebuild may be in line for it.<br /><br />Any suggestions are appreciated, I'm broke atm so the most efficient fix would be nice.<br />BTW, I just put the deckboat up for sale as my 16 year old would like a car. I have a Trailblazer the wife drives but the 16 year old doesnt like to drive it, to big for her. <br /><br />If anyone wants to trade a good late model economy car like a Toyota or Nissan for a nice 22' deckboat let me know. The deckboat is worth 7k or so. :eek:

Hi Triggerr, dont know if you read my thread on Tilt/Trim but the black stuff on the relay pins is OMC Terminal Grease, comes in a small white tube and is use to seal the plugs and wires to stop corrosion.<br /><br />I sprayed Inox in the plugs and on the relay pins pushed them on and off a couple times wiped them with a rag each time and that seems to have cleaned them.<br /><br />Dont know how you jumped the motor direct but you should have a connector just inside the cowl with the green and blue wires running to it from the trim motor, you can split the connector and wire to it there, dont do it to often as you are reversing the polarity of the motor and prolonged use may damage it, for testing it will be OK though.<br /><br />From reading what you have done it sounds like you motor is cactus.<br /><br />Cheers Rosscoe

Hey Rosscoe,<br /><br />Yup, I read your post and about 15 other pages on tilt n trim issues here. My search turned up alot of hits on tilt n trim.<br /><br />I cleaned my terminals and plugs with lighter fluid then blew them dry with a air hose. I wiped up the excess with a paper towel.<br /><br />I jump the blue or green wire by removing the relay and stick a blade connecxtor in the plug to the green or blue wire. I made a test wire with 12 guage wire that I attach to the positive side to a fully charged 12 volt battery. <br /><br />I've used this testing method in the past to chase down this type of problem. Juice is getting past the relays to the motor. Jumping the blue/green wire by-passes the relays. The motor should respond if it is in working order. <br /><br />From reading all the post on this subject it looks like the trim motor has quit on me.<br /><br />One I get the retainer pin out Ill get the trim motor out and pop the cover off. I'm betting on water intrusion and the corrosion that goes with it.<br /><br />I'm having issues getting the retainer pin out, its tighter than a.... well you get the idea :)

Triggerr, when you stuck the positive wire in the plug, did you run a negative wire from the battery to somewhere?<br /><br />Cheers Rosscoe

Triggerr,<br /><br />Did you put positive to green, negative to blue and vise versa? or ground to somewhere else?, I tried positive to green negative to earth on the powerhead and nothing happened.<br /><br />Cheers Rosscoe

That PTT electric motor is a dual polarity motor. Meaning that having the battery connected to the two wires leading to the electric motor makes it run in one direction..... and reversing that connection makes it run in the opposite direction.<br /><br />To test the PTT electric motor properly, disconnect those two wires at the connector, the connector between the electric motor and the relay box. If the connector doesn't exist anymore (which it sounds like it doesn't), cut those two wires so that you can run jumpers from the battery to them directly.<br /><br />Battery positive to electric motor blue and battery negative to green should make the motor run in one direction. Reversing the jumpers, the opposite direction.<br /><br />Hooking one battery jumper to green or blue and the other battery lead to ground (as you've found out) does nothing.<br /><br />This will reveal whether the electric motor is good or bad, eliminating guesswork.

I suspect that you've got some air in the unit. Is the unit still removed from the boat? Don't fill and cap the unit while it is lying on it's back. If it is completely full it won't be right. Keep the unit upright, fill screw out, and topped off with fluid. Keep trying it up and down. Hopefully some bubbly fluid will start to emerge. If it gets no better, walk away for a few hours and try again. Good luck with it.

Joe & Rosscoe,<br /><br />Thanks for the input, I finally got the motor off the bracket and did take the trim motor off. <br />Part of a magnet broke into pieces and stopped the rotor from turning. <br />I cleaned up all the pieces and put it back together.<br />With the whole assembly off the transom I did hook up the green/blue wires as you indicated.<br />The motor spins but the hydrolics dont move the piston. I'm thinking some small particle of magnet pieces got into the system and plugged a line. <br />Yes I filled the system with fluid. <br /><br />Any thoughts at this point?

Update....Long post....<br /><br />Woot... got the trim motor fixed and its running fine now.<br /><br />Heres what happened.<br /><br />After putting it back together and filling it with fluid the pistons wouldnt move even though the motor was cycling.<br /><br />I took it apart again and took the motor completely off and apart. I cleaned it with electronics spray cleaner, getting the gunk and small bits of magnet n stuff out of it.<br />I could only find the larger O ring at my local parts store so I bought it and installed it. The smaller O ring was still spongy and in good shape surprisingly enough.<br />I steel wooled the surfaces that needed it due to corrosion, I cleaned off all traces of steel wool and stuff with the electronics spray cleaner. <br />I also bought 3 new 1/4-20 X 3/4 bolts and the blue stuff for the screws. <br />I hadnt started to drink any beer yet so all was good so far... hehe<br />I put it all back together. I cycled the motor using some jumper wires. The pistons cycled up n down. So far so good....<br />I set the unit back in the transom bracket and started to bolt it all together back in place. <br />I cycled it again and it was erratic....<br />Hummmm, OK, whats wrong. <br />I jiggled one of the wires, ACK, a wire is broken inside the sheathing. <br />Dang, I was worried about this. The original green wire was corroded when I bought the boat and I did cut and butt splice it back then. Actually, thats what originally brought me to Iboats.<br />OK, I take it all off again... Oh, by the way, today is the wifes n mine 21 anniversary. The wife is being a real sport about this.<br />I take the unit apart again....<br />Hummm, what to do? The green wire is corroded/rusted all the way into the trim motor casing. I take it all apart again. I grab the Dremol tool and have a drill bit just the size I need. I drill out the old wire from the outside and carefully drill the wire out from the inside drilling thru the epoxy. Let there be daylight, nice hole thru the housing. The original rubber on the outside is still in good shape. I have 10 guage green wire, it fits perfectly thru the housing but I have to work with it to get it up thru the old epoxy area. <br />I get it up... er get it thru the housing and put a new connector on it. I mix up some epoxy and re-seal the inside of the housing where the wire runs thru it. I use marine silicon on the outside of the housing to seal it.<br />OK, I put it all back together.<br />Yea, it works.<br />I put it on the transom mount and bolt it all together.<br />I cycle it up n down, up n down, several times. <br />Works good. I top off the fluid.<br /><br />Oh Oh, dirty words.........<br /><br /><br />Trim indicator isnt working.... sigh.....<br /><br />I read the manual.....Havent had a beer yet...<br />Dang its hot outside...<br /><br />OK, I have the OHMS at the wires like its supposed to. There is continuity like it says. If I read this right the trim sending unit is bad, or is it the trim guage?<br />I think I sent a jolt of 12 volt to it a day or 2 ago when I was messing with the trim motor and relays. Not sure but I'm sure its something I did.<br /><br />Oh well, who needs a trim guage anyways.<br /><br />Anniversary day..... I call Applebees and get some shrimp covered steaks for take-out. A stop at the local grocery store for adult beverages n soda, I head back to the wife. <br /><br />Nice meal, watch Nascar race, will take boat out tomorrow.<br /><br />Thanks Iboats, <br /><br />Triggerr
