Thanks!

Hello ,I have 2 instruments and a new transducer.Since there is a fault with both I am looking for a wiring diagram.Can anybody help ?

Thanks

I have a diagram but it doesn't have component values and probably wont scan. My Seafarer3 is currently not giving any readings. I'm hoping the transducer is just clogged with Essex mud. I'll look out the diagram and see what can be done with it.

Thanks very much julianc
Does the manual tell you how to adjust the depth ? I am about to give up with the Seafarer.But being a steel boat means cutting a new hole in the hull since all transducers have a bigger diameter .But awould try once more if I had the manual and the wiring diagram.My son lives in Canada ,maybe you could copy it and send it by mail.Please let me know if that is possible.

Regards Cormoran

I can have a go, but its about a 5th copy already - I tried re-drawing it but didn't get very far.

I don't have a manual sorry - just the schematic. I don't think there is any user way to adjust for transducer to keel, there might be a variable resistor deep inside but that would be quite difficult to calibrate.

The big benefit of these old machines is that they are analogue. Digital machines always let you down when there is too much clutter. With a Seafarer you can SEE the clutter - the brain/eye is a much better signal processor than we know how to code.

Of course a modern digital fishfinder is just as good.

How do you know both your head end units are faulty? I brought ours home and connected a condenser mic to the transducer and got enough of a reading from it to tell what was going on.

Think I'm going to have to renew the transducer - what a pain! the current one looks like its epoxied into the wooden hull.
