Volvo D6 Trim Issue

2007 D6 with outdrives... Starboard engine will not trim, port engine will. I took a look and the starboard side is definitely low on fluid. I didn't have any on hand to top it off but I don't here the pump running. Is the EVC system "smart enough" to know it's low on fluid and would stop the drive from trimming? Wouldn't it give me an error if it was? I'm going to pick up some fluid but it there anything else I need to look at? I have read that relays can go bad and sensors. Anyone gone through this?
 
not sure EVC is smart enough.....doubt it is. I would get her to the right level and see what happens then.
 
I just had mine out and no sensor in reservoir that I could see. I did replace my trim motor because it was looking tired.

Easy to test. Disconnect wires going to trim motor and measure with DC voltmeter. If 12 volts is there when calling for trim it’s a bad motor. If not it’s a relay by motor or potentiometer in drive.
My motor looked really bad from outside and worse inside. Still worked.

Thanks wilks, My motors looks better than that, hopefully it's just the relays... Heading there shortly to take a look and I'll report back.

Found the motor only on amazon for $50. Works great

Problem solved!!!
Topped it off with fluid and still nothing but the barn was quit enough that I here the motor clicking.

Pull both relays and ran to Autozone and grabbed 2 new ones, $16 each, put those in and presto, trim works... Fingers crossed that this will be a permanent fix

Always appreciate a cheap fix when you can

Problem not solved!
Ran the boat this weekend and once again no trim on the port side. I got back to the marina on Sunday and with the engines off and the lock turned on the EVC the trim worked... I was just on the boat an hour ago and tried it again and with the lock turned on or off no trim. I´m stumped, anything I should check?
 
When the port side does not work and stbd does, check the voltage going to the trim pump motor. Mine had to butt connectors by the motor to put meter leads in. Have someone look at meter (dc volts) and someone run trim. If the motor is bad the voltage will go either + or - 12 vdc. This makes pump run either way. If the drive is all the way one direction then the voltage will only be there in one direction. Make sense?

Thanks wilks, I think I understand... I'll need to find someone give me a hand. I did go ahead and order OEM relays to see what that does... I can hear something, maybe the motor, clicking when I hit the button. this is what it was doing before and the new relays made it work, but not for long.

Most likely the clicking is the relays.

I also posted on Boatdiesel.com and someone told me it could be just the contacts where the relay seats. Of coarse its a bitch see whats going on but I'm going to take a look at the too. Once I figure this out, which i will, I'll post back and let ya'll know.
 
Update: went to the boat today and pulled and reseated the relays and the trim is back online. I'm about 98% certain that there is corrosion in the plug that the relay seats in. I pull them again and sprayed some electronic cleaner in there and also in the pigtail for the motor. I ran them up and down a few times and everything seems to be working again.


On a side note I did notice that the motor on that side is a little louder than the other side and that side moves a little slower than the other side. Would that be indicative of the motor going out?
