I have HD’s gen 2 10 and 9 touch. Sonic hub and lss 2 if I am not running big motor they flash and then they shut down. If I hit trim button they flash. I am wanting to try to re wire them directly to the battery. Not sure of the best way to do it. I have heard that you need 10 gauge wire Wich is not a problem but not sure of best way to do it and also don’t want battery to drain due to something pulling power any help is welcomed
The way I done my last boat was to run 10 guage tinned wire to a 6 circuit Blue Seas fuse block. I then connected each units power cord to the fuse block. If the power cord wires needed to be extended I used 14 guage wire. I also added a 20 amp switchable breaker about a foot from the battery in the 10 guage feeder.
When you park the boat just turn off the breaker to kill power to your units and isolate them from the batteries while they're being charged.

Thats coming from a voltage drop. I don't remember for sure but I think 9.5v is the shutoff point for hds units. Turn on your voltage overlay and hit the trim button to see what it drops to. My guess would be a bad ground at the battery.

I'm inclined to agree with Semo that it's a voltage drop. When I had a 27series battery running my TM, and my Elite 5DSI is wired through the TM power line, the depth finder would dim - flicker - shut off once the battery had been used heavily during the day. Let off the TM and the screen would quickly brighten back up, but get back on the TM and within a very short time frame the screen would start dimming out and eventually the unit would shut off. I went to a series 29 battery and have yet to experience that again, even after long hours of heavy TM usage.Quote:

+3 on voltage drop. I've had it happen and installed new battery.
Good connections work miracles and so do good batteries.
This also happened to me, voltage was the issue, cleaned connections and installed a new battery. No issues since.
Yep. Me too.Quote:

Thanks again for this valuable information!Quote:
