I did my first break-in run today and noticed some things, but the floor is still dry - so that's a plus. 1) I checked the battery voltage while the engine was running (1500rpm) and it was 15.4 volts. Then at the end of the 15 minute break-in, it was reading 16.2 volts before I shut it down. Now battery is reading 12.77 volts with engine off. Should I be worried? 3-wire alternator is new, but 23+ years old. 2) I installed a little red LED light in the Excite wire from the alternator, but it does not turn off after the engine is running. Does the LED bulb not draw enough voltage and should I swap in a regular light bulb?
