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 - The 8N and the Fox - by Zane Sherman. Dec. 13 1998, Renfroe, Alabama. Last niht I dreamed about the day that I plowed the field of about 10 acres over on what Jimmy and Dandy called the Ledbetter field. I was driving the 1948 8N Ford tractor that Jimmy bought in 48 new This was prebably in about 1951 and maybe even befor the house was built. This would have made me to be about16 years old and I drove the tractor for nothing and would have paid to drive it if I had had any money which I didn't, but neit
