Easiest way to see if the Ablemail is working?

I might have a 007 available for the right price?

Just asking for a friend here, but can you change the cut off voltage on the LB on the BT module? Setting 4 works great, but that pesky 13v! Fridge comes on, LB volts go down below 13v, no AMT, I'd be buggered if the sun didn't come up!
I would love to reduce the 13v cutoff to something less so the AMT works through the night.

The 13v threshold isn’t an issue though as the AMT will work regardless when the starter battery gets to 12.1v as long as the LB is above 12.4v. I’m on setting 3 and it works fine keeping the starter battery at about 12.2v.

Now I am going to make an assumption that "Battery Type" is the battery its charging, not the Leisure battery. So now down to 4 or 8.

No, it’s the leisure battery type. Starter battery is assumed as lead acid or AGM. The reason for a smart alternator setting is the starter battery will sit at a lower voltage (about 80%) on a smart alternator vehicle so it has capacity to take charge from the alternator on overrun and regenerative braking. So for a T6 it’s setting 3 or 4 depending if you have a lithium or LA/AGM leisure battery. Or 7 or 8 if you have high parasitic loads. In reality the default of setting 4 works fine regardless of LB type, it just may sacrifice more LB capacity by kicking in earlier. Either way the AMT kicks in when the starter battery gets to 12.1v anyhow which is plenty to guarantee starting and prevent damage to the battery.

However to satisfy my curiosity Im going to have to go through the hassle of taking my electrics box apart and checking.

Why? The BMT trace shows it working and keeping the starter battery at 12.1-12.2v ish. All the little spikes are it working. If it wasn’t there would be no charge spikes and your battery would keep depleting below 12.1v.

Thats strange. Jonathan at Ablemail know I had a lithium lesire battery when he fitted my AMT but Im sure he said default number 4 is fine. I even remember he used his laptop to do the setup.

Setting 4 is probably more suitable for a Roamer though when it rests at 13.2volts.
I would rather have that with the 12.1v safety net if necessary, I think?!

As I mentioned, setting 4 will work fine, it will just sacrifice more LB power and earlier. Not really a problem, but also probably unnecessary in many cases. I’d be surprised if he left it on setting 4 if he had to use his laptop as that is what it is set on out of the box. Possible he tweaked the figures or had a completely bare unit.

The battery type on the instructions is 100% the LB type, not the starter.
