ST60 log not showing speed through water.

At the back of the instrument, pull off the br and w connectors, make up a jumper with the resistor and 2 spare connectors and fit to the terminals on the instrument. The two wires from the transducer are redundant. Resistor value isn't too critical, your temp readout will be about 25 deg with 10k
 
Update from Raymarine dealer. Looks like it might be the board controlling the display! Apparently, it's very rare for the transducer to go wrong.

Of course the board is much more expensive than a transducer. Oh well, it's only money.

Well, my transducer went wrong, and so have others. That's when I found out how to fix it for about 10p, Incidentally, the Raymarine dealer I contacted couldn't help, but this forum did.
 
hmm - Raymarine DEALER ... ie - vested interest in you parting with your money via them ...
Can you borrow a head and/or transducer to test your transducer/head ?
Call Raymarine DIRECT and find out what they think - they sold us an upgrade to our ST50 tridata with 25% OFF the ST60 tridata ... certainly worth a shot .

There are also quite a number of ST60 heads going on eBay - if you know it's the head unit and if you're not bothered about new then you could quite easily get one of these.
 
Trust me, I will do some more investigation prior to shelling out a pile of cash to someone whose first response is to start changing components rather than fault finding. I did ask what would be step 2 if the PSB wasn't the corrupt component.
 
ST60 log showing ---

Many thanks for all the advice. Oddly the wind instrument was also showing --- but was working OK on the repeater by chart table.
Pressed lots of buttons and now working fine. Think I did a reset more by good luck than good management. Perhaps its the same with the log. Never had the temp display working, not sure what value that is, I know the Irish Sea is always cold!

The magnets are moulded inside the tips of the paddle wheel. should be able to detect them with the tip of a small screwdriver.

Airmar Speed transducers employ a "hall effect" device, this reacts to the magnets and switches on and off with the signal coming out on the green wire, power is supplied to the device via the red and screen wires. It is possible to simulate the pulses coming out of the paddle wheelbyt pulling the green red and screen wires off the back of the unit. If you then tap a bit of wire between the red and green terminals on the back of the unit the display should start to react by showing a speed relative to how fast you tap the wire!
 
Do you have someone nearby with the same instrument and will lend it to you to do a jury rig install and test? I did this recently with some of my gear and it very quickly highlighted what was wrong and then the solution was simpler by far.

Good luck and a cheap solution.
 
Update. Success!

2 things.

1. Pulled the transducer and got rid of the very small mollusc that had stopped my paddles wheel spinning.

2. Did a factory reset and then recalibrated the speed log.

Everything now Ok.

Thanks for all the tips and help.

Does a factory reset on the tri-data also reset the total miles on the log back to zero?
