Ebl 99 not charging leisure battery while driving (1 Viewer)

[Adamsolifier]

Hello guy, my ebl 99 unit is not charging my battery while driving and my fridge stopped working while driving also. The d+ signal has 14v power coming to the terminal into the ebl unit. I changed all the fuses with no luck. Anybody know what this may be?

Have you checked the multi-pin plugs and sockets on the top of the EBL.. ?

They are prone to overheating and failing... I had to change one on mine that supplied the fridge.

Switch off all power, 240v and 12v, then examine each plug, look for signs of heating, a brown discolouration, may not be noticeable until you pull the plugs out.

The plugs and sockets can be bought from Planet 12v

If you have to replace, you will also need a crimping tool .. also available from Planet 12v.

Took the pins out and looks to be all clear. I did change the 2amp fuse with a 3amp fuse a couple weeks ago and before it stopped I heard a lot of clicking coming from the unit itself. Could there be an enternal issue with the unit?

Hi and welcome.

Lots of clicking sounds like a relay trying to operate, possibly another fuse has gone or the relay failed.
Not sure if there is an internal fuse on that model.

Have you checked for fuses (20a ? ) near to the starter battery positive terminal .

Here's the EBL manual which includes a wiring diagram.

Yes I went and actually changed them all just to make sure. I feel the issue may be the unit itself. I have power going to the pins, but seems to stop there. Does anyone know how i could bypass the unit and charge directly to the battery?

Have you checked the fuses by the starter battery a 50amp for charging leisure & 20amp for fridge.

Yes, you can by a battery to battery charger (b2b) and wire directly between your starter battery and leisure battery but that probably won't help your fridge.

yes all the fuses are brand new

hmm, yeah im just thinking about how to get power to the battery in the back without ruining anything.

For the split charge system, the power comes from the alternator/starter battery to a screw terminal at the back of the EBL. On that wire there is a 50A Maxi blade fuse, located very near the starter battery. There will be 3 fuses there, a 20A that powers the fridge while the engine is running, and a small fuse, maybe 5A, that is for the D+ signal.

After going through the split charge relay inside the EBL, the power goes out of a screw terminal at the back of the EBL, to the leisure battery. On that wire there is another 50A Maxi blade fuse, located very near the leisure battery. Also next to the 50A fuse will be a small 2A fuse for the battery voltage sensor wire. If that small fuse has blown, the EBL stops working. To get charging power to the leisure battery from the alternator/starter battery, both of those 50A fuses need to be good.

You can check if the leisure battery connection to the EBL is OK by looking at the voltage at the Auxiliary Charger 2pin connector on the EBL front panel. It's probably labelled 'Zusatz Ladegerat' (= Auxiliary Charger). You need to put a fuse in the 'Zusatz Ladegerat' fuse slot for a connection to be made.

On the EBL99 there isn't an easy way to check the starter battery power is reaching the EBL. Except checking the screw terminals at the back of the EBL, which can be a bit awkward to access.
