Title: Helix 9 G2N 2nd transducer part 2
Post by: Sodaksam on June 15, 2019, 12:43:39 AM
I added the high speed transducer on the helix 9 mega SI.  Worked great for a couple trips.  Good depth readings on plane.  I was looking at a lake map on the unit in the garage a couple nights ago.  I accidentally left the unit on overnight in the garage.  That night on the water the unit would give no depth info.  Nothing at all—like depth wasn’t an option.  It had speed and temp and time.  Talked to my friend who is the electronics rigger in the area.  He said I probably overheated the transducers, and they were shot.  He gave me an idea to restore the factory defaults and reconnect the transducers.  No luck.  We figured i needed 2 new transducers.  Not cheap.  I went out a couple more times with no depth readings which you really miss.  Suddenly tonight i was on the lake and 2D, SI, and DI all worked. Go figure.  I have 2 transducers on order.  I’m not sure what to do.  Will this resurrection last?  Should I replace the high speed TD as I’m to Lake Kabetogama in Northern MN which is rocky and new to me to save a lower un it or prop potentially?  Another thought is that he raised to Mega TD to eliminate the rooster tail, which it did.  Maybe the Mega is doing all the work and the high speed dual frequency TD is dead.  I know, long-winded question.  Any thoughts would be appreciated. Thanks, Sam

Disconnect the Y cable and test each xducer plugged directly into the unit  ...

If all is well - suspect a bad Y cable or intermittent connection in the Y cable  ...

Normally, wouldn't worry about the transducers.  Some folks never turn theirs off on a TM while on the water.  They can wear out over time but one night shouldn't do that and unlikely to be damaged by overheating.  Other types of higher power transducers could be damaged by overheating if not submerged in water.  If it turns out to be the y-cable, hopefully you can return the transducers.

I made the trip.  I brought an extra transducer just in case.  Never needed it.   Worked perfectly.  Hard to explain.
