Thread: HB depth reading issue

Call the Humminbird Customer Service folks back. They will let you know what the next step is.

Customer service sending a bead for the trolling motor head.

Just out of curiosity I ran a ground from the metal strap holding the transducer on the trolling motor to the HB ground. It cut out about half the interference even though it was not wired tight.

It sounds like you may have grounded the foot of the trolling motor when you did that. Check that trolling motor fuse with a meter, not just visually as it should be in the internal trolling motor wiring to ground the foot of the trolling motor. You should tell the Humminbird CS folks this so that they can tell the Minn Kota folks this (they may be working with them to find your trolling motor interference solution).

Sorry to be such a neophyte at this. Just want to be sure you are referring to the 3 amp fuse in the trolling motor head. I put another 3 amp fuse in even though it (my second fuse) did not appear to be blown.

No apology needed, you did well by trying the other fuse. Call the Humminbird Customer Service folks, they have access to more information on trolling motor interference then I do.

Some interference issues are caused by Bleed back thru a multi-bank battery charger ...

If you have the electronics battery hooked to a charger that is also connected to another battery ... Dis-connect the electronics battery as a stand alone battery and test for interference ...

Thanks. Tested the same
