1989 DT 200 Trim Senders?

[R_Andersen]

I have twin 1989 DT200's and neither of the trim senders seems to work at all. The one guage always shows '0' and the other trim guage always reads '50'. I have verified that the arm on the senders moves up and down freely but I get no change in reading. I haven't attempted to remove the senders yet, but I was wondering if they can be taken apart and cleaned up? These motors sat for over 4 years so I'm assuming there may just be a bad connection inside the senders.<br /><br />Thanks,<br />Rob

The sending units are variable resistors so the circuit resistance changes when the trim lever is moved. You can check this with an ohm meter by disconnecting the sending unit at any convienent connection point, hook the ohm meter to the sending unit wires, manipulate the sending unit lever and see if the resistance changes. If it doesn't, the sender is bad (not sure if it's rebuildable or not); if it does, the problem isn't the sender.

On my old DT-200 the sender died after about 7 years. It was basically worthless anyway so I never even bothered to check out why it wasn't working. On my new DT-225 I did't even bother to hook up the guage.<br /><br />Thom

Ok, thanks for the info. Since I have twin's I was hoping to get the trim senders working so I can make sure both motors are trimmed to the same position when running.....<br /><br />-Rob

The senders are a bit tricky in that a multimeter reading does not correlate to what is in the manual. I purchased a brand new sender to work this out. The drama seems to be in the gauge where the wiring in my DT150 was fitted in reverse (lomg story how I found this out). This problem would have existed from the factory as the gauge/sender setup could never have worked the way it was set up.<br /><br />Trace the wires to where the sender unit plugs in and make sure the wire colour correlate all the way to the gauge.<br /><br />craw
