HPUs, trim systems, door seal pumps, autopilots and cowl flap actuators all have motors and should use breakers for overcurrent protection. The alternator field lead should also have a breaker so that the alternator can be isolated. The trim breaker should be set apart from the others so in a runaway trim situation it can be located, and pulled, quickly. Blade type fuses are suitable for most other applications. I avoided Faston spade terminals in my plane and am glad I did. I have only three of these friction connections, two on the Hobbs and one on the alternator, and one (alternator field) has given be trouble. Not a good average. I used solder and heatshrink almost everywhere and have been rewarded with a very reliable electrical system. Regards Brent
