Has anyone experienced your helix units shutting down while on plane? They just shut off and the boat is not even in rough water.

Sounds like loose connections to me.

I just checked them and they seemed fine but I'm going to reconnect them.

mine does that occasionally..,and my hill graph I cant even use because it just flashes. I know my problem is that the person who owned the boat before me used too thin of a wire .I need 14 gauge wire for both of them. I just suck at wiring and haven't attempted it yet

I would use 10 gauge wire directly to battery with a fuse closest to battery. Check collector makes sure making good contact to pins. Also check for any loose connections at the battery.

rewired all mine with 10 ga never another issue, use star lock washers on terminals and double hex nuts on battery connections, also check voltage to if low could do it been there also.

Is it wired all the way back to the battery or did it get tied into existing wiring harness. The proper way is all the way to the battery. If it is wired into your harness, there could be a loose connection somewhere and the wiring probably isn't the proper gauge wire for it and you aren't getting enough voltage for it so any vibrations when running can cause it to lose juice and power off. Also, which type of connector does it have on the back of the unit. Some of the older connectors need to be tweaked a bit to get a good connection even though they appear to be tight.

Mine was doing it. I put some corrosion protection grease on the plugs in the back of the graph and it stopped doing it. I narrowed it down to the plug before I did the grease thing.

Good info. I've got 2 of the Helix 10s at the console and they both do it at the same time. Will run the 10 guage and see what happens. Thanks guys!

Mine does it time to time in any kind of water conditions. Humminbird has replaced my cable collector and it still does it. So my next step is to send the unit back and see what the issue is?

Mine was simply because the plugs were loose. I used/wrapped Teflon tape on the male power side around the post to take up any slack between the two connections.

Like stated usually a connection issue. I have a 2001 Skeeter with a 10 mega mounted on the console. I am wired to existing 19 year wiring a no issues. I would check all the connections before running new wire directly to the battery. If that does not fix it then it might be an internal issue

It's virtually certain a connection issue. I'd strip everything and run new wires from the battery before I'd squander a bunch of money sending anything to Eufala.

Don't know what kind of boat you have, but that's normally an easy wiring job. I've rewired all 4 of mine.

Don't know that I'd use 10 ga. A lot of wire for very few amps but go ahead if you have it. Other than hard to work with, won't hurt anything. 14 or 12 should be enough unless you're running a 30' boat.

Get good wire, good lugs, install properly, and I'll bet your problem goes away.

Shoot some cleaner on the posts in the cable collector. Good maintenance anyway.

GO FISHING !!

Have you checked the software is updates?

All my updates have been done, all power wires have been run to the cranking battery. I may try to spread the pins to see if I get a tighter fit...
