I have a 18TRX. I have a Helix 7 with mega down tied into my Ultrex up front. About half the time, when I start my main engine the helix shuts off. The only way I can get it to turn back on is to remove the power supply from the back of the unit and plug it back in. My cranking battery is basically new, and it’s always been on a battery tender nonstop. I did not wire in my unit in, the dealer did.... but obviously it’s associated with my cranking battery. Curious what the remedy would be?
What specific cranking battery?
If you have integrity, nothing else matters. If you don't have integrity,
nothing else matters.
I guess I don’t know for sure other than it’s the interstate that came with the boat in 2019. I’m guessing whatever the standard is - I don’t have the boat at my house, it’s at the shop. I’m guessing as a group 27 battery, because I replaced my trolling motors with a group 31s.
There is no standard. Many dealers install undersized batteries.Originally Posted by itsahog

Mine came with a 31 series interstate agm cranking battery Mark.

Just because the battery is relatively new doesn't mean it's not going bad. You could put a volt meter on the bow and see what the voltage is dropping to when the starter is engaged. Hummingbird could probably tell you what the voltage level has to be above to avoid shutoff.
Thanks for the replies, I’m guessing mine is also the 31 series, I will confirm next time I’m at my shop. I’ll also take my voltmeter and take a reading. I’m guessing probably running the wires directly to my cranking battery will solve the problem, hopefully.
I wouldn't keep letting it shut off abruptly for to long, I've read it's not good on them.
What gauge is your wiring?
You taking power from the bow panel or wire direct to battery

Not sure, Looks like I need to run to battery- what gauge should I use?
it is from bow panel, dealer hooked it up, I need to run to battery from what I am reading. Need to determine what size wire I need.
What units do you have on the console and are they wired direct to the battery or through a fuse panel. Helix needs separate wiring from the battery. I installed a new breaker panel under the console from the battery then to the new units using 12 gauge to the panel then smaller to the units.
I just finished running 12 gauge tinned wire from the helix at the bow to my consul, hopefully that solves the problem. I’ll know tomorrow because I will have it on the water. The power it was tied into upfront was probably 16 gauge at best.....
Unfortunately it still does it, looks like I’m going to have to run wire right to the battery. I guess the good news is at least I’m halfway there! Lol
One question, since I’ve already got the ground wire grounded at the Council on the power block, can I just continue running the hot wire to the battery or do I have to run both of them?
I did check it is a series 31 interstate AGM battery.
31M AGM
CCA800

Ah 100
after running it fishing today, parking it at the shop checked with the ohm meter - shows 12.8 DCV

I just got through running 10g marine wiring to my console and bow graphs. I installed a water-proof fuse holder and shut-off switch in the transom compartment right off the battery. I haven't been able to test it on the water yet but both graphs are reading at least 12.9 volts and that was confirmed with a digital multi-meter. My console graph would shut off when starting the motor too. I found a bunch of corrosion on the connections under the console - that was me being in a hurry when I installed them initially. This time every connection has glued shrink tubing and is locked down. Cost me about $60.
You may be tricking yourself with the meter. The only way to accurately measure graph voltage is with the unit on. That is difficult since the plug is inaccessible when the unit is on.

I ran 12 gauge wire directly from my helix 7 to my cranking battery with a three amp
inline fuse near the battery, problem solved.
