Sargent EC50 problem (leisure battery)

[LiviBob]

Hi all! Some advice please on a Sergent EC50 problem please.

My leisure battery is fully charged (tested on voltmeter at 13v). I have a solar panel which constantly charges and of course when I plug in to mains.

Problem is, when I select L battery on the EC50, it alarms and flashes red LED by the battery symbol and the bottom LED of the charge indicator. Lights etc don't work when L selected.

So, I have a full battery but it seems the controller is not registering the charge. Have checked fuses at the battery end and on the EC155 unit, all seem to be ok.

Can anyone advise me please?

Many thanks,

David

what's the voltage of the battery at the terminals?

got a multimeter to test it?

and post a pic of the fuses you tested. . . the Sargent should have a fuse at the battery connection points.

13.77 V at the terminal (see photo) and fuse ok. Fuse ok in the EC155 unit as well.....

is it a EC155 you have?

Yes. And it seems to be working ok.

The EC50 thinks there is low voltage in the leisure battery, but we have proved it is 12V +

i would disconect the powerplugs for the EC155,

and check and reseat them.







and check that you have LB voltage on pins 8/9

starter battery SB voltage on pins 5/6

and a good ground on pins 2/3.

Thanks mate, I'll give that a try.

that will effectively reset the EC155 and the EC50 panel . . . .

which may also work if its all got confused.

Thanks mate, I'll give that a try

Resolved.....!! There is a small set of fuses under the driver's seat which I didn't even know was there. After taking half the van apart, we found it.....!!

Thanks for your help!

Good thing is you found out now not in the middle of a trip (I hope!)

This may be a bit late but I felt I still wanted to share my problem in the hope it might help others, my system is the Sargent ec50 control panel with a Sargent ec155 power supply unit, I’ve not been able to use mine for 12 months due to the control panel intermittently kept beeping and shutting down the system suggesting a low leisure battery, I have two batteries linked in my set up and I’m happy to say I’ve finally discovered the fault, it turned to be a loose battery clamp on the negative pole of one of the batteries and a poor earth to body cable on the same negative pole.
Hallelujah hope this helps someone else

It's very easy to miss faults in the ground side because of the way vehicles are wired everyone tend to trace the wires which are almost all positive, but they're vital for a complete electrical circuit.
