..

are they drawing power from the same bat? it maybe that starting the motor drop the voltage the finder receives

Sounds like you do not have your transducer connected.
You will know it is working if you have a bottom sounding. If you have a bottom sounding (depth reading) and it is correct then you may have to fine tune the finder to see the fish.
I have the same finder on my boat. http://njsaltfish.com/index.php/captainsfocus?sid=61

read the book that came with it you got to understand how it works and know how to set your unit before you can understand how it works and what you need to do to make it work and to get to what settings you want ..a fish finder is like a computer you got to program it to your likings .. I have a hd 10 structure scan on mine .. .now that's a nightmare to set but the book tells you everything you need to do and how to do it and how to get what your looking for and how to get to it

If you more then battery connect the fish finder to the second battery.
Or if the Depth finder is connected through the acc. on the boat. The power is being cut off be fore the starter is engaged. By pass this and connect through a correct size fuse.

Hi,

Hope my info solves your problem,
Thanx for using fixya.....

I don't think your old fish finder is the LMS-332C GPS Receiver listed above in the description. You don't need the speed wheel for the fish finder to function just the transducer and transducer mount. You should mount that on the back of the boat towards the center but not too close to the motor and not too close to the side of the board. Don't let it hand below the level of the boat. That should keep it from getting hit by the trailer or dragging on the bottom. Try to make it as level as possible. The green and white wires may be for the speed wheel but i'd need a model number for clarification. Hope this helps.
