• Do you need to unhook the battery from the charging leads to test the charging leads? What if the charging leads show 0, but the battery lugs on the converter show 13.6.

• I have a 2021 Imagine XLS that I purchased new in August 2020. We have been out on two trips of about 2.5 months each with no problems. We returned home in early Feb and after being home a few weeks I noticed that the interior lights were really dim when I turned them on. I checked the batteries and sure enough they were low. I charged them and they were fine for a short time when the problem reappeared. After watching your video I tested my system with a multimeter and there is no power coming through the RV charging to the batteries. Obviously, I have a blown fuse or something similar. I have checked and all my breakers and fuses in the electrical panel are good. There is one inline fuse and one inline breaker near the battery. I've checked both of them and they are good. Where do I look next? thank you

• I dont know where my battery is. It isn't there. I have a 1988 Fleetwood Terry I just bought. The panel shows my battery as FULL

• Thanks

• So where’s the fuses or breakers for my converter if 8m not putting out power from it?

• This Battery Tender is excellent!ㅋ>imgs.love/BatteryTender?Ф    Superior design, waterproof and fantastic for my wave runners!! I highly recommend it!

• The Coronavirus brought me here.

• I press the trailer, Batt. button and it says full charge. Yet I know for a fact that the battery is nearly dead. The trailer is plugged in constantly since my sister lives in it. So, to get a "real" reading, should I try disconnecting from the AC power?

• If I'm plugged in and my battery isn't charging where is a good place to search cuz I'm not finding on the converter

• Thanks for posting

• I'm not getting 12v at the battery connector going to inverter…what should be my next step?

• good information for rv simple and to the point. Good video.

• Now I want to go check my battery and charger just for fun!

• Couldn't ask for a better tutorial. Thanks!

• My batteries are weak or dead in front of my rv how do i charge them ?

• the charging system has to have a source of energy.. so this is plugged into an AC source?

• Is it the same voltage for AGM batteries?

• Thanks for the quick service, the plans arrived yesterday. [ Check Details Here=>t.co/y2DqsHWwZD  ]  I have just about finishing a boat when they came with an idea on how to finish up, and they gave me a few lessons in boat building! Thanks to them!

• So what do you do if your charging system is showing no voltage?

• Great video,

• Very informative, and to the point. Thank you.

• Thank you.   If, while plugged into 110, the trailer charging system is working properly and the batteries are up to charge, but don't charge while hooked up to the truck after a day of driving, what could the problem be?

• I reconditioned my dead car battery a few weeks ago with your program and it's been working perfectly since then! My car battery was completely dead before I used your methods [Check Details Here==>https://paper.dropbox.com/doc/Reconditioning-Any-Type-of-Dead-Battery-znFRbqzq5jpI3ZJjZKXX1 ]. This just saved me hundred s of dollars on a new battery!

• does it stop charging when it is full or always continuous charge? I leave mine connected all the time.

• Thanks for putting this up

• ty happy holidays
