I?ve got a B&C LR3-C voltage regulator in my -8. Mine failed on the way to OSH in 2018. Made it in on battery power but the good news is the folks at B&C were fantastic. They were at OSH and provided me simple troubleshooting procedures to find the problem. I quickly figured out it was the voltage regulator that failed and they FedExed a new one to OSH right away. I was able to swap it out while there and have had no problems since. No charge from them for any of the troubleshooting or replacement voltage regulator despite the fact that I had been flying with it for 3 years and I had installed it in the aircraft prior to that. Well past the warranty period. Things happen, things break, these guys stand behind their product. I would certainly use any of their products.
