The three wires (usually yellow) that charge the battery and run the lights etc. go directly to a regulator/rectifier to provide the proper direct current voltage for the 12 volt DC system.

The separate wires for the ignition system go directly to the capacitor discharge ignition (CDI) unit which powers the ignition coil and the spark plug.

+ 1. The exciter coils of a Generation 1 stator powers the CDI (ignition system) with alternating current, regulator/rectifier uninvolved.

Besides the three wires mentioned, does your replacement stator have two separate exciter coils with two wires connecting them?

Race Tech aftermarket stator works fine; upgraded regulator/rectifier also, even though stock R/R would probably handle everything.

Just a characteristic, assume it's the same for all upgraded stators: Race Tech says higher-output stator actually produces less power at lower rpm than the stock unit; higher output at higher rpm.

Was your bike running before you started this Hi-output stator project?

How many wires are on your replacement stator? Do they have OEM style plastic connector terminals on their ends? Or do you have to cut and solder splices?

Do you have and Know how to use a VOA meter? Do you have a service manual? Did you test the 2 wire connector on your OLD Stator and compare it to your Hi-output stator.

Has the "Doo-Hickey" been upgraded on your bike or should it also be attended to while you are in the LH side?

Just a quick comment on rectifiers. They are just a voltage limiter that keep you from frying your battery, etc. Most bikes will produce more juice than needed and the rectifier dumps the excess to ground.

My bike was running with the oem stator.the esg 450 stator came with a plug and play connection and it didn t start the bike at all but i didn t put the meter on it to know the output i just sent it back to electrosport .my doohickey is done i put the 2014 in it that is made on one piece and a lot thicker and i had to remove 3 coil of my actual spring to make it pull again with 1/8 play .the teflon had some groove in it and even the new spring was not working anymore.

Sorry djeady, that is incorrect!

The Rectifier portion of the VRR converts AC (Alternating Current) from the Alternator Stator windings into DC (Direct Current).
It is the Regulator portion of the VRR which limits the Voltage, by dumping the excess to ground.

Voltage Rectifier Regulator.

And as has been previously discussed has nothing with Spark on a Gen 1 model.
