merc 1993 175 hp trim and starter problem

[dobbslee]

My trim/tilt works sometimes, but when it doesn't the relays are clicking. Could there be a wiring problem or is the trim motor on the fritz. Also my starter is now engaging when you cut the battery switch on, so there must be a short in the ignition switch (quicksilver push to choke). Any help will be appreciated.

Start by making sure you have a fully charged battery. Then ohm out the trim switch,wiring, and solenoids, before suspecting the motor at all. The motor is the *last* componant in that food chain.<br /><br />Also, I would *think* it's your ignition switch on the starter issue. UNLESS turning the key to ON also switches the +12v to the starter solenoid and the START portion of the switch grounds the ground side of the solenoid, then it could be a stray grounding issue. You could disconnect the START wire from the ignition switch and see if turning the switch to ON still causes the problem.<br /><br />I'd reccomend you get the manual for your motor and study the wiring diagrams. then grab a volt/ohm meter and determine your electrics are doing what the wiring diagram says the outta.<br /><br />-W<br /><br />

Thanks for the info. I have the manual, but it is vague about certian voltage readings in the trouble shooting. I will give it a try again and see what happens.

It's all pretty much straight 12v DC all the way.<br /><br />If it's like my late 80's one, in the end game the fat blue one (solenoid to motor) should go hot for up, and green hot for down<br /><br />-W

dobbslee,<br /><br />I had a similar problem with my tilt motor. Solenoids were clicking. <br />I first checked battery voltage using my volt/ohm meter. Then checked the connections to the terminals on the solenoid, and also checked the terminals when hitting the tilt switch. This confirmed I had voltage coming OUT of the solenoid, 12 volts. <br />Then I used two jumper wires and connected them to the tilt motor, black, green, and blue. I don't know what color wires yours have but my two power wires are green and blue. Check them one at a time to +pos. <br /><br />My problem was my motor. It didn't work when connected to the battery. After taking the motor off and then the end cap off the motor, this was confirmed.<br /><br />Hope this helps.
