Battery power issue
I have a 1981 T-21 I believe. I believe because I just don't know yet. Bought this baby from a guy that had jury rigged just about everything. I was hauling it to a place to begin to work on it everything was fine. Disconnected from the truck went to the RAISE/lower switch went up fine. Decided to check the inside lights, FINE, Today, went over to lower the top ------nothing. No inside lights no lower switch nothing. No power at all on DC and never put it on AC, any suggestions. Nothing changed from everything worked to nothing worked but 12 hours elapsed.
Very curious. :confused: |
Battery still charged, check with multimeter or testlight.
Was refrigerator left on 12volts. will drain battery real quick. Check for bad connections at the battery. Fuse blown (not likely) loose connection elsewhere than battery. |
Thanks didn't even consider the refrigerator being on. I'll start there.

And, Beekeeper - if you placed the Master Switch into the "Raise/Lower" position (you would have done that to attempt the lowering), it will disable ALL internal 12V electrical items (lights, water pump, furnace, etc.) except for the 12V feed to the refrigerator. That is ALWAYS active if selected at the refrigerator switch.
But, if the Master Switch is in the opposite position and all 12V equipment is dead, you probably have a dead battery. It can be charged by the onboard converter if you plug the trailer into 110V AC shore power. If you have a multimeter, a fully charged new battery should read about 12.7V at the battery terminals under no load. - Jack |
Master Switch
But, if the Master Switch is in the opposite position
I have to find the Master Switch. I am not with the camper right now but I truly believe that is the source of my discontent. We were checking all the switches, and most were unlabeled and when I went to let the top down...nothing worked. It's like, there is one switch that is switched and where is it. Claude |
Claude, I'm not real familiar with that vintage of a Hi Lo, but I'm sure you'll find the Master Switch right inside the main door at floor level to the left, Typically, push the top of the switch-- everything is on. middle position--travel position, nothing on but refer if selected to 12V--push the bottom of the switch--power to the raise/lower switch (usually right next to the Master). I'd suggest you take a bit of time to view the videos. Not all will apply, but many will explain the uniqueness of Hi Los. Welcome!

Bee, In the "search" mode, enter" HiLo "video" owners manual.. youtube". I'd really like to see these vides in the Reference Manuals section for faster access by all.

I always have have to add this caveat. On my 2001 tl the raise/lower position is pushing in the top of the toggle and "everything on" is the lower spot.

I think Hi Lo workers did that just to keep us on our toes!

Thanks Jack.
In the video the master switch is shown as two separate switches. On mine, the master switch is one switch (I believe) I will see if I can post a picture of it. I will replace the switch and see if it is it just a broken switch. (For a start) |

That certainly IS a possibility. In that case, I'd suspect a dead battery.

Brand new battery. Been working to much to get squared away on the repair. I did however, get the picture of the switch taken and the solenoid outside. Power comes from the battery directly into the solenoid. Maybe it has an open somewhere. Will begin in earnest tracking wire breaks etc soon as I get a day off and a tester. I appreciate all the info. https://www.hilotrailerforum.com/memb...ydraulics.jpeg

I may be stating the obvious----but were you reading the batteries with them plugged in to shore current and or the truck? in checking them- make sure they have time to "rest". I would make sure they have no charge going into them or out of them for at least fifteen minutes or so and preferably over night to get a good indication if they are holding charges or not. unplug them from everything- including your tow vehicle and let them sit. then check after awhile and see what you got. It SOUNDS like the refrig is using more than you can out back in while you are on the road on DC. and it takes a good deal of charge to top things back off even if you are "plugged" in.

Then, to me, this sounds like a short of some kind though I wouldn't know where to start. Maybe a bad ground which is intermittent?
