Location: Long Prairie, Minnesota | Hey all…..hope someone smarter than myself can throw me a bone here. Bought myself a 681VS late last summer and it came with a Helix 12 on the console all wired up. Here is the problem….when I am running the big motor going between spots, it works fine. When I get fishing it will run for a bit, but within 15 minutes it says there isn’t enough volts and shuts down. Figured I fix it this spring. Pulled the boat out this weekend and got everything going. Fired up the Helix and right away said “low voltage” and displayed 8.2V. Grab the multimeter and tested the battery and it was at 12.59V. So looking at the power wires for the Helix, there are three wires coming from the graph. White (which is hooked to the positive terminal with 30 amp inline fuse), black to the negative terminal, and a green wire that they just have hanging there not hooked up to anything. Should it be hooked up to something? Why would the graph read such a low voltage when the battery is charged and working fine? Any help/suggestions would be appreciated. |
