I have an 82 Mercruiser 260 ( 5.7) with a prealpha drive. It has been trailered due to storm repair work. During a periodic start up with muffs, I noticed that at one point, the water wasn't flowing out of the drive as it had before. The exhaust risers was getting very hot and I suspected that the impellor was shot so I shut it down. Total run time was about 10 minutes at 15oo rpm.
Then, I attempted to adjust the trim down, and realized that it was suddenly inoperative. It will click once when I try raise it at the control handle... without further response from the trim motor. If I try to lower at control handle, not even a click. At the trailer remote switch, I get a click when try to lower, nothing when trying the " up". I checked out the manual # 6
troubleshooting steps. I tried to apply a ground via a jumper from 12- on the bat to ground connection on the pump. Nothing.I briefly touched the jump from the 12+ to the ground at the motor and got the expected sparks. I jumped both solenoids, green
and blue wires, with no response. I cleaned the bullet connectors for the trim switch and even disconnected them and tried.. same lack of response.
Since it will not spin when I jump the solenoids, I doubt if they are the culprit.
I am going to buy a multitester and check the 110 amp fuse. I tapped the motor with a rubber mallet. I took a look at the trim sensor wires to see if they got cooked if things got too hot back there.I used merchant seaman phrases at it, no response. It is stuck in the up or raised position.
I would appreciate any further suggestions. ( I expect that I will just have to
go through the entire voltage check procedure ) Thanks
