I'm hoping to get someone to point me in the right direction to cure the interference in my new Helix 10 SI Mega. I have done a search but the results come back rather broad and unrelated to my problem. The facts.....
Installed new Helix and Ultrex last week.
The wiring in the bow panel was turning into a plate of spaghetti so I added a Blue Sea fuse box to the bow. I ran 16 ga wire from the Johnny Ray wiring blocks at the cranking battery through a switch to the fuse box. The fuse box has the Helix, the heading sensor, a digital clock/air thermometer, and a indicator light.
Also behind the bow panes is the 24v TM cables as well as the factory wiring for the tilt/trim and anchor light. All this wiring gets a little crowed together....my first concern.
Here's some pics of how the transducer and I-Pilot link wires are routed....
Here is a couple of examples of the interference I'm getting.....
Easy to see when the trolling motor is on and off. The depth also jumps from actual depth to something much more....usually 18 or 19 feet but once I saw it reading 524 feet.
I'm assuming that my first step would be to get the power to the Helix off the fuse box and run dedicated wire to the battery. Should that be shielded wire?
Should I try to get the wires coming out of the panel into the Helix separated from the transducer cable? How about the close proximity to the trolling motor battery cables?
I have seem posts referring to ferrite rings to help with this....what size and where do I find them?
I'm just trying to get pointed in the right direction before I start tearing everything apart.
