Default help with wiring in a heading sensor to the minn kota terova

im going to be setting up a bow mount minn kota terova i pilot trolling motor, and in the instructions it says not to use anything else on the battery that your using for your trolling motor. does this include the heading sensor? also i immagine it would probably be best to have a fuse for it. what type of fuse would you suggest for it? Thanks for the help!

Fuse for the trolling motor or heading sensor? I think most people wire the heading sensor to the boats electrical system not the TM battery.

I never installed mine. Trolling motor works fine without it. I believe it’s needed for being able to make adjustments while in Spot Lock. I didn’t want the clutter on the deck.

I just installed my sensor on the back of my boat near cranking batteries. I wire it up so when batteries are cut off it would not draw any current if I let the boat sit for awhile. I was told by a MK dealer no fuse needed.

Mine runs on the cranking battery, but I also have a battery switch that shuts it aall off when not needed,
As for function, it is my understanding that the heading sensor comes into play when you use "auto pilot" (N) so the boat tracks in the direction you select. I use it all the time to work a shore line.

The heading sensor calls for a 1 amp fuse. If you don't have any other battery on board, then you have no choice but to connect it to the trolling motor battery. It uses little current, so it shouldn't be a problem. Not sure if it uses power while not in use. I know when you first power it up, the led turns on for 3 seconds, then goes out. Once it's paired, it blinks every 3 seconds while in use. Anyway, I'd consider putting a switch on the positive lead, to avoid battery drain. Or just disconnect it. No need to re-pair it after disconnecting it.
