controller reading( -1 volts) on rv battery, then checked the controller on my daily driver 2010 toyota pre runner.. still read (-1 volts)

the Sunforce 60031 i had went bad after about 1 1/2 years and i went back to my old Sunforce 7 amp controller which works just fine for my needs (110 watt panel with three batteries).

It's not reversed polarity. If the polarity is reversed the 63001 is completed non-responsive. I have the same unit. It is displaying -1, but otherwise appears to be functioning normally

I agree with T. Thomas, sounds like reversed polarity - it's easy to do as the documentation is not very clear on the wiring.

Only thought I have is that you have the polarity reversed on the battery leads. If the leads are correct, the controller is faulty.

I made my own. The controller has terminal strip screws for all the inputs and outputs. I have the controller within 5 feet of the battery. Use at least 12 gauge wire for each, the positive and the negative. Larger gauge would be better. I crimped on connectors to fit on the controller screws and my battery has screwed studs that I also crimped connectors on to fit.

lets say your battery is at 11v and a high sunlight charge from the panel pushes in 13~14v, the read on the battery will show a "soft" 12v. the shade comes in and the battery goes back to 11v. Next time you see it, be amazed to see how many amps your controller cranked up.

Install on the positive and negative on the battery. Use a volt meter and check to make sure you have all the batteries in series and it shows 32 volts. Make sure when installing you switch to tow mode to avoid shorting out any micro relays in golf cart. If yo need additional help please contact me

I just took these readings from my solar charge controllers remote display. It appears to draw about .4 amps on low and .5 on high. I ran it for a while on both settings and it held steady at those readings. It was plugged into a cigarette adapter I'd install in the RV for small load devices.

I had the techs from the battery company hook mine up when they replaced my batteries and they hooked it up to the positive on battery #1 and the neg on battery #4. I haven't used it yet but I will this summer when I leave Florida.

Mine did the same thing. Called traxxas and they walked me through resetting the battery mode. No charge for the call. Somehow I put it in the wrong battery mode.

The aux pwr connection must be at least 4v. The min volt reading can read down to zero v with the same accuracy...it cannot read negative Volts.

Can not be certain but would guess you have a battery with calcified plates causing a short. Bottom line a dead battery.

Check you volts coming from the panels. It should read about 14-15 volts. What type of batteries do you have? Sounds like the problem is with your batteries.

what are you measuring? Are you measuring batteries? If so, then it's pretty normal to have a higher reading except the 3.7V one.

Yes, set the scale for DC range, and place the two probes using the correct polarity so the meter reading is a plus (+) reading. If the batteries are under load when doing this, the voltage may be less than 24vdc. If the two batteries are not connected to the trolling motor, the reading could be 24vdc, otherwise, if near zero or substantially less than 24vdc, the batteries are either bad, shorted, etc. or need recharged. Also check each battery separately.

Also this should read the battery resting voltage (what your battery has in it stored right now) without even turning your key. When the engine is running game and the alternator is going it should read 13 or 14 volts. MIne reads 14.5 or something like that and it is normal while the engine is running.

A test you can make is to directly connect the panel to the battery, correct polarity important or you will fry things. If the voltage is 17 volts or under you are good to go. If it is still over 18 volts you will be over current and ruin the battery. You cannot have the controller set to 24 volts for your 12volt battery!

You might have a bad battery. A cell can be intermittent and the voltmeter will still read okay, since it doesn't check current. I suggest you test each battery with a battery load tester.

I know I'm really late on this conversation but as an alternative to the answer from Bill L. is to take your vehicle to an Autozone or O'Reilly's or some other auto parts store that will connect a code-reader to your vehicle for free, make sure the code is from the O2 sensor and have them clear it. Disconnecting the battery on newer cars can be a bigger pain because of all the advanced electronics. At the very least it will save you from having to reset all your radio presets!

There are many reasons this could happen. The most likely is that either: 1) Your system is wired backward. 2) Your wires are too thin. 3) You are running too much current through the controller. The controller has a max amp rating that is 3x higher than it's continuous current rating, meaning, if you are always pulling full power from your batteries you will ruin the controller.
