Topic: Voltage | Bass Cat

Voltage

A couple yrs back i ugraded my graph wiring to the package Bcb offers. I hooked my 2 graphs a 12 gen 3 and 9 lowerance along with the nema. I have had not the first issue!. I added a 1042xsv and the gls10 recently. Since the addition seems im seeing some 11.8 volts on my front graphs. With the addition i used 10 gauge marine tinned wire. I use a big northstar that is 2 yrs old. I check my voltage before i leave after my charger has been unplugged a couple hours. Shows 13.1 volts consistently! I do fish alot without running the big motor. Livewells , garmin units running all day. Big motor hasnt let me down yet. Why such the voltage loss? Am i losing that much at the terminal block at the console?

check the voltage at the dash voltmeter when this happens and then you will know the actual battery condition. If you ave a voltmeter check the actual battery when this occurs

Make the graph end wires as short as possible.

If you are now seeing this on your other graphs then you battery is getting tired possibly. It could be dirty terminal posts and loose connections. Use Vaseline petroleum jelly on connections to reduce corrosion issues.

The wire is enough to carry the amperage, though the graph wires are all too small in our opinion. Make those short and keep travel low on those lines.

Clean connections. Not thinking the northstar is bad. Im gna investigate a little more. The garmin power wire is kinda long. I may shorten that wire some. When i installed the new unit(garmin) i did check voltage at the terminal block and it was good.
