Wiring a VSR
Submitted by Jackfrost80 on Mon, 2022-09-26 13:34
Still rewiring the boat and onto the switch and VSR which I had installed by a boat mech.
He has wired the positives to position 1 and 2 on the 4 way switch using 30a cable but looking a diagrams I should have it wired to the positive of each battery.
Should I replicate whats been done or run positive wires to the batteries? At the moment it's running 30a to 115a battery cable...
I think I've come to the answer typing this but keen to hear thoughts.

go with the manufacturers
go with the manufacturers specs - chuck a fuse inline if unsure

wiring a VSR
I'm presuming your VSR has 3 conncetions, Battery 1, battery 2 and an earth wire.
Battery 1 will be the main starting battery, battery 2 will be accessoriies/house/whatever.
Providing the battery switch reflects these battery numbers (ie #1 is the starting battery)
it does not matter if the VSR is connected to the switch or directly to the batteries
NOTE : if you are running the motor with the batt-switch set to '2' the VSR WILL NOT charge batt-1

Cheers mate. Yep that's
Cheers mate. Yep that's exactly what I have and I run the motor on '1' as my starting motor and have the anchor winch connected to '2'.

ALWAYS........
... have your motor running (fast idle) when using your winch
Check and se if your FF/chart plotter can show voltage on the screen. If it can then set it up to have a permanent display. You will then be able to monitor the charge on batter 2 and watch what happens when the winch is under load.
If you have a voltmeter on the dash, check which battery it is monitoring - probably battery 2 as Im guessing the dash electronics are all battery 2.
If this is the case you should consider adding a VM showing batt 1 voltages

All good mate, always use the
All good mate, always use the winch with the engine. I have voltage display on my Furuno and I have Century battery monitors on both batteries with alerts to my phone if they drop below 70% charge and then again at 50%.
