wiring?

6 posts in this topic

I just got around to rewiring my hb flasher and now when i use my trolling motor the flasher will not show the bottom my transducer is on the transom and i have a bow mount. If i am running around with the gas motor it works just fine slow or fast. I would rather not have to have two batteries in the boat since i don't have room. My other boats that i have owned have only had one battery and everything ran fine at the same time. I have it wired through a fuse pannel with a 1 amp fuse that was in the manual. There is nothing in the troubleshooting that has anything to do with it. Any suggestions on what to try?

So I'm clear, you have the trolling motor and the depth finder on the same battery, correct?

If so, that's likely the problem... you're getting interference from the trolling motor. Do you have a vexilar, or other 12V battery? Try (to isolate the problem) wiring your depth finder directly to that, and see if it works better.

Yes you are correct marine_man. I've got two extra batteries for my ice fishing flasher i'll try using one of them this afternoon when i go out and see if it works. I've always used one battery in every boat the only thing that is different is that they where transom mount.

And that's a possibility as well for why it won't read, but let's start with the more straight forward stuff first.

Well i made it out for 4 hours and it worked fine hooked up to the other battery. So is there anyway to make just one battery work or do i have to live with a extra battery in my way.

Not that I'm aware of... Trolling Motor interference with a depth finder is something that happens... and as far as I know there's no solution short of a separate battery.
