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 - Hydraulic Basics - Part 2 - by Curtis Von Fange. In the last entry to this series we gave a brief overview of hydraulic system theory, its basic components and how it works. Now lets take a look at some general maintenance tips that will keep our system operating to its fullest potential. The two biggest enemies to a hydraulic system are dirt and water. Dirt can score the insides of cylinders, spool valves and pumps. Wate
