Parasite Draw On 12volt System
« on: October 09, 2018, 08:24 AM »
So! I noticed when I switched to my house batteries and just wanted to draw on the batteries for lights. The TV on/off light was on as well as the micro wave light was on as well as the TV antenna booster light was on. How do you guys by pass all these other draws on the batteries so your not sucking them down with unnecessary draws? Hm?

Are you aware that you posted in the parent directory and not in the electrical section? Anyway, aren't the TV and microwave 110 volt? Are you still plugged into shore power? The antenna booster, if it is the original, usually has a switch.

 :)rotflmao I have no idea how things are hooked up in this rig. D:oH! When I hit my inverter every thing comes on. TV, I have one of those new fancy HD antennas that you have to hit a button and it lights up like a pinball machine. The micro wave lights up. The inverter lights up. Shoot the hole rig lights up like the Christmas tree in time square in December. D:oH!

Well, If you are turning on the inverter then you are turning on the AC converted from the 12 volt batteries. That is why things are lighting up. Simple solution is to not turn on the inverter and just use the 12 volt lighting instead. There has to be a switch on the inverter.




And you are still in the root directory, you know the place, where it says " do not post here". :)rotflmao :)rotflmao :)rotflmao :)rotflmao :)rotflmao :)rotflmao :)rotflmao :)rotflmao :)rotflmao :)rotflmao :)rotflmao

well, now you know the answer. It's getting on your hands and knees, and tracing source to destination. My RV I thought I would get away with not doing specific maintenance or maybe letting certain things be - but the truth is, the whole rig had to be gone over when I first purchased it, and it did take a lot of time, and trial and effort!


For example, I've pulled about 20-40 feet of wire out of the chassis dash, and sorting electrically in the coach - both jobs took a few days worth of effort and hours of my time. It's all good to go for now because of that time and effort investment.
