Did his warranty cover all of the replacement parts? In other words, you have only paid for the original cost of the kit, and the 2 replacement rec/reg units were supplied at no cost to you?
hugh is actually the one who sent me the dyna regulator. i believe it is from RM Stator. i was not given an explanation other than he has been testing with the dyna regulators and they seem to hold up better, so I will offer my own explanation The CDI system different state than the PMA. The CDI actually uses for source coils off of the stator to fire the ignition. This in theory offers what I call a roadside feature where, as what has happened to me in the past, should any component of the charging system fail you still have your ignition to power the bike to get it home or to the shop etc. perhaps the single phase regulator that comes in his kit is simply too weak for the CDI stator
The HD Type Regulator is a Mosfet unit, we have been testing them on our CDI system for a bit now, as we did find that our original 15A regulators were not working up to task (the rating was proper, on paper, but in the real world, a handful of folks proved otherwise) - we sent out a replacement 15A which was promptly killed as well.
So, we sent out the $$$$$ Mosfet Unit, which we have been testing with awesome results. In a shunt type system (such as our CDI and PMA) the regulators have to work overtime with the use of newer low draw electronics. This wasn't an issue 2-3 years ago, when most builds were using High Draw 55/65W Headlights and such. However, with the affordable low draw LED stuff hitting the market, the existing regulators were working overtime to shunt all of the energy not being used. To an extent, a Regulator can be considered a wear item, just like brakes, tires and chains - especially when paired with a low draw and a high output alternator. The HD Mosfet Unit from RMStator has proven excellent, although it comes at a cost of about $129 plus shipping from Canada. We are going to start including them with our newest run of systems, and are looking at a quality Mosfet Unit for our 3 Phase PMA Systems as well.
The Mosfets use digital technology, and were suggested to us directly by RMStator as a much better upgrade over the Standard Regulators. I've talked extensively with the Engineers at RMStator to ensure that our systems are compatible and working up to par - its nice having a contact with a manufacturer that cares.
As for warranty claims, we always want to make things 100% - its our goal, no matter how the damage occurs (we've replaced many components over the years due to poor installs, neglect, etc - at cost or often no charge to the customer)
