Default non electrical systems

Discussion at the airport today amongst some RVrs. What constitutes a non electrical system? Can one have a battery and starter but no generator/alternator and qualify as a non electrical system in an airplane? I have not been able to find an FAA definition that addresses this.
Thanks

The absence of an alternator or generator means you don't have an electrical system, per the FAA's definition.

An electrical system is defined as having a Battery and Engine Driven Generator. An alternator IS a generator!

If you have a battery and starter with no engine driven generator, you do not have an electrical system. ref: ?91.215(b)(3)

It depends on your context. Are you alluding to Mode C / ADS-B waivers for aircraft without engine-driven electrical systems? If so, here it is in a nutshell:

If an aircraft was originally certificated without an engine-driven electrical system, and has never had one installed in it's history, then it is eligible for the Mode C / ADS-B waiver. The key gotcha here is that it cannot have ever had a generator/alternator driven by the engine ever in it's history. Example: If you have a J3 cub that came from the factory with an A65-8 engine without a generator, and then subsequently in it's history had a had a C85-12 fitted to it with the generator pad on the accessory case blocked off and it never gets used for a generator or alternator it is still eligible for the waiver. However, if a previous owner installed a generator and operated the aircraft, even for a day, then the airframe is never eligible for the waiver. Even if a subsequent owner removed the generator or installed a A65-8 in its place. It cannot revert to being eligible. Only aircraft that have never had an engine-driven electrical system in their history can operate under the waiver. This means that most Rotax-powered experimentals, even with a rope pull starter, are not eligible as the Rotax has a lighting coil on the flywheel. Hence it has engine-driven electrical syatem.

Note that a wind-driven generator or alternator does not affect the eligibility as it is not engine driven.

So, no provision that the generating system has to be able to support the ADSB/transponder installation?

Nope, capacity is not mentioned.
