Q 5. -This is the reason why IA said not to install a lithium aux battery with the SmartpassSo further to this post:

I've now received answers back from CTEK Technical Support:
Q1. - Why would the temperature sensor appear to be shrink wrapped onto a ring connector and attached to the negative terminal of the service battery?
Q1 Answer: Strange attachment of the temp sensor. Usually, the hot spot area is on the top of the battery around + terminal.
Q2. - Why would the smart alternator cable not be attached (the vehicle does have a smart alternator)?
Q2 Answer: Connect the smart alternator cable to ignition on signal (KL15+) if you have a smart alternator. If you don´t know if your vehicle is equipped with a smart alternator? Connect it anyway.
Q3. Why is the LED between the service battery and output consumers permanently lit when nothing is connected to the Smartpass output terminal? Doesn't this indicate that the service battery is providing current to some consumers?
Q3. Answer:
View attachment 7822179
[I've queried this as the light is not flashing and exclamation mark LED is not lit]
Q4. - Would there be any benefit to this system in fitting a D250SE but not attaching any solar power input?
Q4. Answer: Yes a D250SE will top charge your service battery. The reason of
above led indication can be missing D250SE or/and not activated smart alternator function?
[I don't understand the second sentence]
Q5. - Are there any wiring diagrams or schematics to show what's inside the Smartpass?
Q5. Answer Unfortunately, no diagrams. available, but a Smartpass 120S is a smart combination of relays (actually MOSFETS) that connects starter and service batteries. This enables current from your alternator to charge both batteries. The SMARTPASS 120S will not control the voltage applied to the service battery. For that you need a D250SE installed in parallel. The current through the SMARTPASS 120S to a service battery depends on the alternator output voltage, cable length/ dimension and the charge acceptance of your battery. The max continuous current is 120A. Start assistance. SMARTPASS 120S automatically connects the service and starter battery, if the starter battery on its own is unable to start the engine. After the start assistance function has been activated, SMARTPASS 120S will display a fault indication that remains until starting has been achieved without the use of the start assistance function.
