Humminbird problem???

**Locator79** · 07-05-2010, 11:18 AM

Replaced the transducer on my unit a couple weeks ago, and everything was working fine. Now graph reads fine if I do not hit the pedal. I can the turn the TM in either direction, and graph works. Once the pedal is hit, and TM is in motion, I get a fuzzy distorted screen (depth and temp still works) I let off and screen goes back to working properly. I have had this unit and TM on my boat for the last 2 years and have had no problems. I have not changed anything other than the transducer. Anybody ever had this issue before?

Sounds like you might have the transducer too close to the prop?

I had that problem when my troller and locater were hooked to the same battery. If the voltage dropped below a certain level that would happen to my screen. Try hooking your locater to a seperate battery and see if that helps. It worked for me.

Good advice.

Also go to Humminbird support FAQ pages and search noise.

I will try that. I don't see why it would make a difference now??? I have ran both of them of the same battery for years and never had a problem. I did notice today that if I have my TM set at 1 or lower I have no issues, I can also run at 10 with no issues. Anything else is distorted. As far as my transducer goes, I have it as far back as it can go without touching the skeg on the TM, this to has been the setup I've been using for years.

Cable routing could be the problem. Never run a signal cable parallel to a power cable (no more than 12 inches). Intersect power and signal cables at 90* when possible. EFI/RFI will bite your butt. Guaranteed.

Have your battery load tested. It could be on the verge of dying.
