A test bucket wont work, A 200 khz transducer will generally not work in anything less than 2' of water, due to surface clutter. If the transducer is working, you should hear it make a ticking sound.

When you got the 17000 foot reading was your range set to auto?

How is the transducer situated on the boat? Sometimes turbulence and bubbles from the hull can cause erroneous readings, including unrealistic depths, or no depth at all. Stop the boat and turn off the engin e and anything electrical to see if problem repeats itself. If it only crops up when the boat is moving then it is most likely the transducer location.

SOURCE: Depth Sounder does not display depth

I will see if I can get mine off the hull for testing. Still have found no procedure. Thinking about just replacing the sounder with another unit.

It sounds like you have a software problem. The first thing to try is to go to http://www8.garmin.com/products/gpsmap235s/download.html and download their updates. If that does not work, you will have to take it to an electronics depot, unless you are comfortable with opening it up. There is a possibility that a connector has come loose inside the unit.

Why doesn't the new cooling fan motor work?


Did you check voltage and ground at the fan connector? Check applicable fuses. Can you check applicable trouble codes? Will the fan turn on, if you turn on the ac?

Some fans may not turn on, till the temp reaches around 220 degrees F, that excludes the ac.

There several issues that could cause the fan not run, another issue could be the coolant temp sensor. Does your temp gage work ok?

My two year old Garmin 95 depthfinder has worked great until a month ago when the depth read-out started rolling over rapidily and continuously between 18ft and 32 ft. In adition, the water themperat


Hi Tom!

I believe I'd start troubleshooting with the power supply. Disconnect and clean the cable ends with Fluid Film (I swear by this stuff) Check the crimps and make sure they're not loose. Pay special attention to the ground connection.

With your temp not reading correctly in addition to your depth rolling, this usually indicates a common fault. (Usually ground.)

Check the data cable and socket on the control head for corrosion (again, Fluid Film is your friend) If that doesn't fix your problem, then a "hard boot" or reset of your system might solve the problem(s).

Hope this helps you out.
Good Luck!

My Garmin 400c dual beam transducer keeps freezing up, it will flash "0" depth and then go to a "updating software" screen.


check your battery voltage. Low voltage can cause errors end prevent the sonar from starting up. If charging the battery doesn't work then contact garmin for a replacement.

If the transducer is out of the water, you will not get a reading and see the flashing depth. You should hear and feel the clicking in the transducer when out of the water and working properly. Are you getting a temp reading when out of the water?

This sounds like an oven thermostat problem. Try checking the oven control knob for voltage as you turn up the temperature as well. There may simply be a failure to pass voltage at the contact points and a temp control may solve the problem.

Built in transducer is not picking up/transferring depth to graph


I havew a Minn Kota trolling motor on a Z21 Ranger. Minn Kota has a built in (puck type) transducer on the motor. I have a lowrance 135x on the front. The lowrance will read the temp but will blink the depth. I switched out the depth finder with another 135x with the same results. I have a 522c gps unit networked together and mounted on the console that works fine. Any suggestions on the problem with the 135x?

Charging problem 1991 volvo 240


14.6 means your voltage regulator or diode is suspect Despite having new alternator .Ive cross refrenced your smptoms in the haynes workshop manual and alternator is your only end answer.The haynes test is to start vehicle with multi meter connected across the battery terminals,increase the engine speed until the reading remains steady should be approximately 12 to 13v and no more than 14v.switch on as many accessories as possible(headlights heater blower radio etc)check that the alternator maintains the regulated voltage at around 13 to 14v.If the regulated voltage is not as stated then alternator is to be repaired/replaced.Good luck with it and a happy new year.
