6v Regulator for a Generator System

Looking at this, does it simplify things?
Alas, no. It regulates voltage but has no current limiter. It is a high-side switch for the field coil, whereas your generator requires a low-side switch. It does not have a cut-off function to prevent battery discharge via the field coil.
 
Ok, I thought it must be too simple. Commercial versions of it were only $25 (25 Euro at current rates).

There's not many commercial versions of my regulator at all, and they are about $175!
 
I did say it was a rough layout . Just a starter for you to improve on.
I suspect the cost of building your own reg won't be much different from buying an off-the-shelf one. Have you considered that? I see them advertised for around £32 ($50).


Do you have a link? I couldn't find any correct ones except at two or three times that price.
 
Sorry, no link. I confess to simply searching for "6V motorcycle regulator" and didn't check datasheets, so they may not have been 'correct'.

Alec, can you check the Pebble representation of the stripboad layout? It seems like a few components are missing. This is my first time with Pebble, so maybe I'm not reading it correctly.

C1, C2 and TVS aren't shown, because I added those to the simulation after I did the layout in Pebble. I can't re-open and edit my Pebble file because it got garbled . There seems to be a bug in the Pebble software: it doesn't save files accurately on my Win10 system. D1 and R1 aren't shown because they would be on a separate assembly within the headlight. R11 isn't shown because its format/size would depend on your choice of component. There is space on the layout to accommodate C1, C2, TVS, R11.
 
Yes, the Pebble illustration isn't showing very well for me either. Unfortunately, I can't access it electronically to place the remaining items. I'll print the picture out and manually add the items to the paper copy.

Just so I understand, the horizontal lines (black, yellow, orange, red, etc) are jumper wires, is that right? Why the different colors?
 
Yes, those are jumper wires. Arbitrary colour choice, except that I like to associate dark colours with ground/negative and bright colours with the positive supply or thereabouts.
