I thought I knew how TC circuits work. How will a series resistor decrease the discharge time?
On a side note, and I haven't really thought this through, but one wonders why "we" can't just go to a solid state device for the VR. It might even be possible, depending on field wiring and current, to use an Alternator regulator AS-IS at least for the VR section.
I recently gutted a defective VR on my "new" Cub Cadet 102 and replaced the cutout relay with a bridge from RadShack, so that part is pretty easy
There are & have been SS VRs for generators, just not wide spread, probably due to volume demand.
Time constant is RC for a resistor-cap ckt and L/R for inductor-resistor ckt.

Today's Featured Article - When Push Comes to Shove - by Dave Patterson. When I was a “kid” (still am to a deree) about two I guess, my parents couldn’t find me one day. They were horrified (we lived by the railroad), my mother thought the worst: "He’s been run over by a train, he’s gone forever!" Where did they find me? Perched up on the seat of the tractor. I’d probably plowed about 3000 acres (in my head anyway) by the time they found me. This is where my love for tractors started and has only gotten worse in my tender 50 yrs on this “green planet”. I’m par
