Projecta tech support said heat sensor cable has deteriorated. To fix, cut off old terminal connector and fit new one. Crimp, not solder connection.
We did this and still not working.
Given the device is 4+ years old is it likely that the unit is "Stuffed" and needs to be replaced.
We need a solution as we can only charge house batteries with solar ATM (3x 120 ah) and they are 3 years old and not holding charge very well either.

Sound like charger has not been working for properly a while, not fully charging the batteries will stuff them. also when you put in the 3 batteries were they all brand new, if not putting old AGM'S with new disaster. charge will only recognize older batteries and not fully charge any thing new to capacity. I found this out also the hard way. Auto electrician said all would work ok. Three years later my new batteries stuffed old battery lasted an extra 6 months. Some "experts" I now take with a pinch of salt. Do you own research some times need lots. I found this out when I changed to Lithium system. So much conflicting rubbish. Good Luck

Been through all that, Aotolecky told me gel would work with my 2 agm's. Wrecked the lot. Existing batteries all matched been in 3 years.
The charger has been fine until these errors started coming up. Looking at replacing the Projecta with same and new AGM's. Hoping I can hold out until I get to the coast as prices are rediculous where we are now.
Try Victron. Long reliable history & ours have never missed a beat.
Enerdrive also have a great reputation but are more expensive.

The Projecta charger incorporates voltage sensing wires inside the charging cables.
These voltage sensing wires are insulated from the charging cables up to the point where they connect to the battery.
If the voltage sensing wires become broken or the charging cable has been cut or extended then the charger can't measure the battery voltage and an "OLC"error is displayed.
OLC is not generally a temp sensor error !
If you cut the charging cables (+ve and -ve) you should be able to see the insulated voltage sensing wire in the centre of the cut cable. You may need to strip back some of the insulation of the sensor wire to ensure that is able to contact and measure the battery voltage.
Quote from p13 of Projecta manual
Note: These battery chargers include sensor wires that run parallel to both the positive and the negative DC leads. This allows for accurate voltage measurements
to be taken directly from the battery. It is strongly recommended not to cut the DC leads during installation. However if the DC leads are cut, ensure that the sensor
wires are included in both positive and negative connections

Snippy,
A couple of years ago I was looking for a good MPPT controller & tripped over this crowd - their prices were good. That is if you need to get new gear & Bob recommends the brand too.
Before going elsewhere & as a temporary solution if all else fails, can you go back toward the charger/controller & jumper in new cables ie shift the battery connection point back towards the charger? The sensing may not work correctly & you will have to monitor the voltages more carefully with a multimeter.
PS - did your "Aotolecky" help with the cost?

Re=did the connections as advised by Projecta, still no go.
Autolecky, no help there. I asked for a quote to do our electrics when we bought the rig. "Let's call it $3,000 and see how we go on the day." Not hard to work out my response to that one.

You obviously want to stick with Projecta, I have their solar panels which are brilliant. Victron (all my electronics) they do have a 50amp charger, maybe they have other models but I haven't looked thoroughly, that charges 3 batteries independently.
Don't know how you would wire that in!

Hi Ken
Now I am worried (I think)
In my motor home I have a Projecta IC2500
It was under the bed and difficult to get to and see what was happening
I cut the wires added anderson plugs to each end and when I need to connect, I connect from outside the bed and can also use the the projecta to charge other batteries .
I obviously did not read the manual about this sensor wire(I did it about 3 years ago)
I do not get a fault and seem to have no problems
What should I do about this sensor wire ?
Is it possible I have clamped the sensor wire when I added the anderson plugs and all is ok?

Hi kgarnett (Ken)

Thanks for the above info, it is something that I shall remember
So this is why you people are techies, and I am just the oil rag, assisting the engine driver
I had an (expensive to me), Projecta 15 amp, 240 volt battery charger. It does not have a screen just a mode button
I had it hooked up to my house batteries, under a seat. As I was parked under a tree, with 240 volt available
I had the 12 volt wires going between the enclosure box, and the seat, while I was sitting on the seat, for nearly 10 days
Next time I used the charger, was on power mode, and it would not produce any more than just above 2 amps, same when I put it back to battery charging
I threw it away, as I assumed that the internals, were just not robust enough to travel in a motorhome
It now seems like I may have crimped the wires, and travelling had broken the sensing wire/s inside the insulation, of either 12 volt pos or neg

Hi
If it was mine and I was given the information given here about the sense wires, I would open up the unit and trace the internal connections for the sense wires at the control board. Then make up two new wires and run them to the battery terminals externally and firmly connect them. If that fixes the problem then make a permanent solution using that principle. If it does not then look for other problems. Any electrical tecko could do that for you.

Here are a couple of photos of the voltage sense wire which is incorporated into the charger cables.
If the cable has been cut, you will need to strip back some of the sensor wire insulation so that the sensor wire is in contact with the current carrying wire. preferably close to or at the battery. There are sensors wires in both the +ve and -ve cables.
At the charger end the sense wires are drawn out of the current carrying cables and are connected to the circuit board. It would not be terribly difficult to install fully separate sensor cables. If it were me I would install a polarised two pin socket on the back panel of the charger so that I could run separate sensor wires direct to the battery.

I took the wires out of the anderson plug today
Sure enough found the mentioned wires that I had not stripped back
The insulation was just broken from crimping the connectors, so I guess just making contact with the main wires so not giving a fault on the unit.
I will have to go back to reading manuals more carfully
Thanks for the information

the issue only becomes apparent after modification from the existing supplied projecta wiring. one needs to be aware of it if shortening/lengthening the cables or changing the terminals.
The IC range of projecta charges are excellent bits of kit, usually, with very fast voltage sensing and stable output.
That said, all machines fail eventually

The cables weren't modified or lengthened, they simply failed. Problem started intermitently a few months ago and gradually got worse.
Cutting and replacing the lugs was advised by Projecta, and also others on this post.
