Hello all, this is my first( of many I guess) posts as I've almost finished to restorate an old 1976 Kz750 B1.
My charging circuit wasn't working so I've replace the regulator\rectifier with a YAMAHA one (see pic) and it's working pretty well.
The only downside of this readjusting is that the field coil has become a permanent-on unit (brown to 12v, green to earth), as the regulator only work on dissipating the extra current, not by stopping\limiting the field coil as the original one does.
I was also considering to not drain the battery when the engine is not running to attach the field coil after the engine run switch so it will be powered only when RUN is selected.
I've read a lot on this forum in the past days but I haven't found a solution like this, do you think this may work on a long term or there is something I am no thinking of?
I noticed almost every time the solution is to buy regulator\rectifier from
oregonmotorcyclepartsoregonmotorcycleparts
and honestly they looks great, but at the moment due to covid and to shipping costs and time to deliver to Europe I would prefer to use a different solution.
Thank you for this great and super helpful forum.
Merry christmas all the way from Italy.
