I recently bought a 1995 ELPTO 115 out of FL. It's in extraordinary shape for it's age. Upon receiving and installing it I noticed a "gurgling" sound when using the T/T when raising the motor. Serviced the T/T unit with new fluid and purged the air from the system. After a few cycles it simply quit working. Motor is working.
I called Mercury and they verified my thought that something was up with the hydraulics....seals, etc. They also stated that they design the units to last 10 to 15 years and recommended that I have the unit rebuilt, which I'm having done at present.
I decided to pull and install the T/T from my 75 ELPTO on the 115 as it's essentially the same unit and it works flawlessly. After a 13 month total rebuild of my boat I'm obviously anxious to water test the new to me engine and actually fish too!
So, with all of that said, I have a predicament. 3 wire vs 2 wire T/T units....
I've purchased the harness to do the conversion....(relays vs solenoids) However, they did NOT send any installation instructions....no schematics, etc. I've searched and searched all over the net with very lil success.
I think I know how to wire up the blue/green wires, but, am lost as to how to wire in the power and grounds. If I go direct to the battery I'm bypassing the switches so I know that's not the route. I'm VERY concerned about wiring things up incorrectly.
ANY suggestions, advice, schematics, etc etc etc are GREATLY appreciated!
Btw, I'm not a complete idiot hehehe.... totally rewired my entire boat myself.....25 circuits, soldered all connections, etc.
