Transducer question

[Larry&Leisa]

It appears I have 3 on the 370 and none of my electronics such as depth, speed, temp, record accurately or at all (which I knew going into this deal). I have tried to search here and on the net in general but I can't find any info. Can one test a transducer itself (and how)? Are they interchangeable or brand specific or is it just different frequencies? I understand that it might be the displays as well, but just trying to understand the transducer. (I'm also not sure if these are thru hull or in hull yet)

I believe there are only two frequencies and multiple transducers on the same frequency will interfere with another. I would test each component individually.

I have two but I use one or the other.

What make and model of electronics do you have. You say you have 3 transducers, but you don't know if they are though hull or not which is pretty basic, but probably irrelevant. The parameters you list: depth, speed, temp are most likely handled by 1 or 2 combination units not 3.

We need more information to help you.

I'm assuming these are the transducers.. or I could be a moron... but this really is all new to me. :huh:

The electronics are :
Raytheon L750 Fishfinder .. display lights up.. no accurate readings
B&G LCD Chartplotter.. lights up.. but I think the board is probably toast as the on switch also controls the contrast ( when there is a contrast button)
B&G Network GPSplus.. won't power up
B&G Network Quad.. won't power up
B&G Network Pilot.. won't power up
Furuno 1731 Radar Display.. array turns.. no targets acquired..

Thanks for any insight. :smt001

The two transducers side by side are likely the speed and depth for the Network Quad.
The B&G Network instruments get both power and data over the single network cable. The fact that none of them power up may mean that the "first" unit isn't getting power, so subsequently, none of those down the line will, either.

The "first" unit will have one of the cables tied into the power supply, rather than being daisy-chained in between other units. This would probably be the Network Quad. Check the wiring and the power to that unit first.

The B&G Network instruments are top notch. I only have the autopilot, but I promise you no one could give me another autopilot for free. Despite her ancient technology, she'll hold me to 0-65' of cross track error (per gps) through 4' quartering seas- straight as an arrow.

BTW, all the manuals are online at B&G.com

Thanks for the info T. I've found the manuals already, but back to my original question.. is there anyway to 'test' the transducers and if I have to trade out some of the electronics can I use the same 'ducers? ( and at least I did figure out that those WERE the transducers :smt038)

You won't be able to use those ducers with new equipment. But the housings are still good so you can buy new "inserts" to go in the housings specific to whatever you upgrade with.... most likely..really depends on the exact housings you have as they do vary in size slightly. There is an adapter cable to make your Raymarine ducer work with new Raymarine equipment. So to answer your question, you likely have options, the exact options depend on exactly what you have there. There should be labels on the "plug" end of those ducer cables with p/n's.

Thanks Jim, good info. So really there isn't a way to test the 'ducer to see if that's the problem rather than the equipment.

if units wont power check voltage on power cables first
when voltage is too low they will not turn on

Contact Myles Electronics at BandGservice.com. He's extremely knowledgable about B&G, especially the older stuff.
As I said, you need to check for voltage at the units and be sure they're properly networked. It could be as simple as a blown fuse... the fact that none of them power up would seem to indicate this.

If you confirm power at the units, call Myles and he can help you troubleshoot.

Thanks for all the help guys. I really haven't had the time to get to checking out the power supplys. Just was thinking about if checking the transducers might be easier or if was a source of failure to look at first.
