I wanted to have an idea of how much the few phantom loads were drawing when the devices were not in use. The easiest place to test this is at the fuse panel but FR leaves a lot to be desired with their fuse labeling! I started by simply pulling fuses one at a time to see what went where. In this 'table' I have listed the fuse number, followed by the label that was on the panel, and then what is actually powered by that fuse.
# : Label : Devices
1 :
2 : Porch : porch light, sink light, awning, awning light, water heater, water pump
3 : Kitchen : dinette light, L/R light, L/R vent fan
4 : Bath : bath vent fan, bath light, entry area light, kitchen light, range hood
5 : Refer/Furn : firdge, furnace
6 : Living Room : LP/CO detector, tongue light
7 :
8 : TV Boost : TV antenna amp
9 : Radio : stereo, 12v socket and usb charger
10 : HHT : tank heaters
11 :
As you can see there is a WHOLE bunch of stuff on the bath fuse that isn't even near the bath, and what the heck does the tongue light and LP/CO detector have to do with living room? I don't know that I will take time to redistribute any of these but it will sure be nice now to know which fuse is causing the problem!
I did rearrange some of the circuits where it was easy to do so. The changes look like this...
# : Label : Devices
2 : Porch : porch light, tongue light, awning, awning light
3 : Kitchen : water heater, water pump, sink light
4 : Bath : bath vent fan, bath light, entry area light, kitchen light, range hood
5 : Refer/Furn : firdge, furnace
6 : Living Room : dinette light, L/R light, L/R vent fan
7 : Detector : LP/CO detector
Now that I knew where everything went I could test for the current draw of the devices, and where necessary get behind the device itself to isolate it...
- Fridge and furnace together = 15mA - not worth digging deeper
- LP/CO detector = 55-77mA
- radio = 42mA - powered off
- usb charger = 38mA - nothing plugged in
This tells me that the radio and usb charger are going to eat about 1Ah of battery capacity per 24 hours. Not the end of the world, but I might install some switches for them in the future.
