    After reading a thread on here about EBL problems....

    I decided to try and familiarise myself with my Moho EBL setup...

    Apparently its a Schaudt EBL251... installed under passenger seat on a 2014/5 Knaus A class.

    From new (April 15) I had a Growler and 100w solar fitted via Vanbitz.

    Now whilst reading the instruction manual for the EBL.. I have come across something plugged into Block 2 - which as far as the manual goes is a socket for a solar regulator...

    However, Vanbitz have fitted a separate regulator in the cupboard immediately below the panel ( Victron MPPT75/15...)

    I seem to recall them saying I got a free battery master with the install also...

    Anyway .... the EBL block2 has this black box plugged into it... it has a single LED light on - currently green

    Any clues as to it's function?..

    It is the battery master, it will be connected between the solar regulator and the ELB solar input for the starter battery. The unit switches on when the hab batteries are above 13.6v and trickle charges the starter battery. Is is a trick used when using a solar regulator with a single output.

    Yes its the battery master that will show a red light when transferring a charge from the leisure bat(s). I fitted mine as instructed between the leisures and starter batteries. However mine does not transfer any charge until the starter battery drops to around 11v. Is mine duff?
    Need @eddievanbitz to comment on this.

    I'm sure I read that the MTTP installed has "gubbins" inside to dual charge - like eg 70/30 - Hab and Starter regardless... and can be user altered via an interface lead or via Wifi ... if one "feels the need"...

    11volts is flat

    It transfers when there is a voltage differential of 0.75VDC

    what is the voltage on the red wire when the engine battery is say 12VDC

    Vehicle bat was reading 11.4v and got 13.1v on red lead (leisure bats) with fuse removed and hey presto stuck fuse back in and got the red transfer light so its down to bad connections on the single arm blade holder connectors supplied with the battery master. Have now replaced them with more adequate fuse holders. Now starter bat over 12v and leisures 13v. So bat master now back to green light and being allowed to do its job.
    Thanks to OP for posting this thread and Eddie for informing.

    The Battery Master doesn't need external or additional fusing, so long as the original wires are not extended as the Battery Master has automatically resetting internal fuses.

    The "single arm blade holder" should only be used with the supplied shrouded blade, which keeps the connection secure, a blade fuse shouldn't be plugged into the splice

    Soldering is obviously better
