Regarding your blog post on the battery charging regulator/rectifier. I may have a problem with mine; specifically, the batteries have difficulty holding charge. Even with the DC circuit breaker pulled there is sufficient current leakage to drain the batteries. I have tested the resistance from the battery leads at 8.5kohms. I suspect that this may be low, but have no other reference. This same measurement is true when the external capacitor in this circuit is disconnected. The regulator is the only other obvious leakage to ground. What should it’s resistance be? Finally, your blog post mentions that these regulators are repairable. How is the potting material removed.
