installation wiring question

I have a Next Step 2 (i.e. this one http://www.amplepower.com/manuals/ns2/ ) that was installed by the previous owner of the boat. The boat's wiring was a real mess and in cleaning it up I wanted to validate that the Next Step was wired correctly.

My boat has 2 batteries (1 house, 1 starter) and one engine (one alternator). The existing wiring does not have any wires connected to TB2 (in fact there is no wire block on top of table 2, it is just pins sticking up) When I look at the manual ( http://www.amplepower.com/manuals/ns2/ ) page 2, TB2 Pin 1 says it is optional, all good, but if that is optional then what powers the parallel solenoid? I do have a solenoid, but there is no hot (small guage) wire going to it.

Thanks

This may be an early NS2 when the parallel solenoid was an option.

thanks Coulomb, but I don't think you understand my confusion.

If you just look at your online manual here ( http://www.amplepower.com/manuals/ns2/ ) it says that the wire from TB2 PIN 1 is optional, but it does not say the solenoid is optional. If you don't have a wire from PIN 1 then how is the solenoid powered?

thanks

Sorry, in the very early units the code to operate the parallel solenoid was only programmed into the microcomputer if the parallel option was ordered. With the code, a terminal block was also added, and I think a parallel solenoid was shipped with the order.
