DC and AC Loads on a R31

[Newtugnut]

Based on a Link10 battery monitor I put in, plus an AC ammeter, here is the current list (no pun intended) of the various loads. More will be added later. I may have missed some in the TBA list

Note that all lights are LEDs except for the running lights.

DC LOADS
.8A Quiescent load (house battery sw on)
.3A Quiescent load house battery sw off)

Vee Berth
Rope light .7A
4 lights @ .2A ea., night light .1A ea
TV 2A
Fusion Stereo .9A

Head
5 lights .7A total
Head pump TBA

Main Cabin

Dinette lights .6A
VHF Radio RX TBA, TX 1W TBA, 25W TBA
Plotter (Radar off) TBA, (Radar On) TBA
TV 2A
Engine bus heater: Low 5A, Medium 7A, High 10.4A

The Cave

I did not see the Nova Kool refrigerator. Good list and thanks for the effort.

I'm concerned by the quiescent DC loads. Those will kill your batteries when the boat Is stored.
When the battery switches are OFF the only load should be the bilge pump sensor and that should be a few micro amps.

Many other items are powered all the time such as CO alarm, Propane alarm, stereo memory. The Garmin autopilot pump controller has power connected constantly, even when off it probably draws a small amount. The battery charger will draw some current from the battery when AC is off. The automatic charge relays are constantly sensing battery voltage.

I have a Victron battery monitor in my R27 and see almost 200ma current when all battery switches are off. The battery monitor itself draws a little bit of current!

I disconnect the batteries during winter storage.
