Trim Up and Down Problem - Clicks Both Ways

[djfam]

Started out de-winterizing today in preparation for striper season. I had to replace a bad trim cylinder, which I did and when I went to bleed to system, nothing except clicks from both up and down (the tilt motor ran minutes before I started the work). This is a 1982 Mercruiser 470 with dual solonoid - 1 for up, 1 for down. I just bought the new batteries today so I know I have plenty of juice. Per the manual, I followed the test for no operation/clicking on page 531. I tested voltage at the input of both solonoids - 12v no problem. I tested voltage at the output side of the solonoid as the up/down switch was being pressed - 12v as well and 0v when not pressed. This is what I should expect. correct? The down solonoid appears to be the one clicking loudest. Am I looking at bad solonoids or should I check something else? The manual is somewhat ambiguos at this point. Is it normal for both solonoids to go bad at one time? Also - I cleaned and checked all the connections as well, so I dont think it is that.

Any help you can provide is appreciated!!! Hopefully my fishing season is not a goner!

If your getting 12 volts on the wire going to the motor it will run if its good.

Ayuh,... It sounds like the solenoids are Workin', but the motor ain't...

Make sure the Motor is gettin' a Good Ground...
If it is,... The motor might be goin' Bad...

So I did a check of all the wiring and found a bad ground. The motor is now working both up and down. The drive isnt moving yet, most likely since I still need to bleed the system after putting on the new trim cylinder. I ran out of daylight to do it today. I'll let you know what happens.

Thanks to everyone who commented and helped out.
