I have been looking at references in this forum to electronic ignition systems for my CB77 and I think the above statement, although widely believed, is incorrect. Charlie's Place state that a regulator is needed for their system but I can find no such statement on the Sasche web site.

The installation instructions (https://www.elektronik-sachse.de/ZDG3/s ... 2/&lang=en) don't mention it and the wiring diagram (https://www.elektronik-sachse.de/ZDG3/H ... m_cb77.jpg) shows their unit attached directly to a stock CB72/77 electrical system. All that is done to install it is to disconnect the condensers and connect the unit in their place.

Given the cost of the C.P. regulator, this improves the affordability of the Sasche unit.

I have asked for clarification from Sasche but have yet to hear back.

You might consider the regulator as an insurance policy against damaging the ignition system and possibly the battery. If you do the correct wiring mods when fitting a regulator you will have a better all-round electrical system with proper voltage control.

Podtronics has been around for some time, and if you are feeling adventurous there are quite a few regulator/rectifier units out there for less. All these units are just a single phase bridge rectifier combined with a Zener diode to regulate the voltage.

I just bought one from SparckMoto for a CB160.

Great product from great people.

I'm not arguing that a regulator is not a good thing; the battery will especially love it. Given the cost of a simple regulator like a zener diode, Honda really should have included one.

Yes - they copied the Lucas system from a couple of years too early. Later British bikes included the Zener diode and heatsink. A very simple but effective addition.

When the 3-phase rectifier on my CB400F failed in the 70s I just bought a Lucas car rectifier for a fraction of the price and it lasted for ever...... :-)

Well, here is my correspondence with Elektronik Sachse. It seems that their web site is misleading and that the ZDG3 unit does indeed require voltage regulation if you are using your alternator.

Our system needs 12V from the battery, nothing else. Strictly
speaking you can leave out the alternator and regulator/rectifier.
Then you have to recharge every 2-3 hours. That's how we operate our
race bikes.

For road bikes with alternator you need a mechanism to limit the
alternator voltage to approx. 11V-14V. This is done by a regulator.
But the stock one will do as long as it's working as designed. You
*can* upgrade the regulator as well (we happen to build regulators
as well). But that's *optional* and not a requirement.
