I am having a problem with my trim and need some help. The trim switch on the cowling that I added works perfect with no problems. The switches at both the shifter and the bow do not work properly. The shifter only trims the motor at about 50% speed and the bow only about 20% speed. I thought that it may be bad wires so I ran new wires from the back to the shifter with the same results. I thought it might be from a voltage drop so I ran jumper cables(from car) from the motor to the the shifter with the same results. I am now leaning towards the solenoids being week but am not sure if this happens or they just go completely. Any suggestions or ideas would be appreciated.

Thanks

Wiring and switches should not be an issue either they work or not... The relays are what power the trim motor so I would look to the connections on them and the grounds need to be checked real close...?

Also under normal conditions a relay either works or doesnt its just a heavy duty remote controlled switch...


Be sure to check the connection from the starter relay that connects to the trim relays...

sounds like you have incomming power problems from the switch to activate relays.... check the voltage comming TO the forward switches willing to bet its low and chattering the relays. thus causing things to run slower than normal

It's possible for a relay or solenoid to make poor contact and arc internally if the coil voltage is low. This could be a combination of inadequate wiring (small or dirty connections) and solenoids damaged by the low coil voltage over time.

hope it helps.
