Hi All,

I'm planning on installing a second solar panel tomorrow. I'm pretty confident I know what I'm doing with that and, aside from cable routing, I don't forsee any problems.

On the recommendation of those who know on this forum, I also bought a battery master for trickle charging the engine battery from the leisure batteries. It's an N&B Arto 79 2012 3.0L so it has a B2B charger fitted as standard, but that only works when the leisure batteries are over 13.5v so it didn't seem to be working very well in the winter.

On scoping the job today I noticed this small device which has similar wiring to the battery master - so I'm wondering if I have one already fitted, or if this is the device that N&B fit to do the charging (and which doesn't work until the LBs hit 13.5v). It's completely unmarked. Any ideas what it is? Or, if not, how I can find out?

Thanks

Chris

Yes, a battery master and the green light indicates its charging your engine battery (y)
You now appear to have a spare.
