Recently our sounder quit. It is an AIRMAR B-66-V, 6 pin plug
. The Garmin
unit is flashing a “SOUNDER TURNED OFF” message. There is no setting to turn sounder on and or off.
Took the main Garmin
unit to SEA-TRAC for testing and it worked as designed with their in tank test area, with their sounder connected. So there is little doubt that that our sounder has crashed.
I have checked all wires and pins for issues, with no change. Thinking that there might a broken or defective pin in the sounder, 6 pin plug
, I replaced the wire set to the sounder and main unit, which produced no change.
face was checked by a diver and cleaned, no change.
Right before the problem developed I had been running speaker wires very close to the transducer
The rest of the Garmin 198c works perfectly as it always has.
Really am running out of items to check, so I am thinking of installing a through the hull
unit until we can haul-out, and replace the sounder. Cannot afford to haul at this time.
Apparently there is a fly in that ointment as we have cored hull
of wood with glass either side, for a total thickness of 1 7/8 inches. 1/2 “ of glass outside and 3/8” inside with a 1” core
. Is there any way this can work
with a water
for the sounder. All thoughts appreciated and welcome.
