All trim stopped working,Troubleshooting

[jonny rotten]

I just put in new trim solenoids,Was working fine in driveway and first time out.Got to the ramp back..nothing
The solenoids click,up,down
Troubleshooting:
12v at solenoids
Used a jumper from 12v at solenoid directly to pump (blue,up)Nothing, no spark no movement
Used a jumper from 12v to small blue terminal WHILE using up at throttle,spark moves up (no button,nothing)
Used jumper from large blue terminal to small blue terminal While using up at throttle,spark,moves up(No button,nothing)


I cant figure out why if put power directly to pump I get nothing but if I use a jumper it only works when switch is applied,grounds at terminals are tight with no corrosion

Is the black wire coming out of the motor attached to the ground stud on the mounting frame?

Yes tight with no corrosion,I though maybe ground,how would I test.I'll loosin it it up now, clean and tightin,but I doubt that's it.And if bad ground why would it work with jumper,but only with switch applied?

Mr. Don S. , i'm having trouble w/ my Adobe and cant open the file . is there another way I can get it ?
While i'm at it , and I hope i'm not hijacking , my trim doesn't go down all at once . it stops , I release the button for a few seconds , then does it 5 or 6 times to get it all the way down .

Blacksting, you need to start your own threads when you have questions and not hijack other peoples threads with your questions.
