1945 A charging wiring

If the L pole on the VR is feeding the light switch, will the lights be able to be used when the tractor is not running? Currently the light switch is fed by the lead off of the cut-out switch when running, and through the ammeter to battery when not running. This also allows a reading of discharge to register on the ammeter. I would like to keep the same functionality. Is this possible? I was thinking of just leaving the L terminal unused and feeding the lights with the Bat terminal. Not quite sure what to do. Thanks, Tom.

Yes they'll still light with the tractor off. The advantage of using the L terminal to feed the lights is that when the lights are on the current they use in effect kicks the charging system into high gear. If you don't use the L terminal to feed the lights, you will likely show a discharge unless you have the engine running very nearly full throttle whenever the lights are on. Example.... On my '51 B, the previous owner bypassed and did not use the L terminal. With lights on, it discharged unless running full speed. Now that I'm using the L terminal to feed the lights, it doesn't discharge until the throttle handle is less than an inch from dead idle.
