I hear what you say but the nature of spade connectors utilise a knife (mal
e) connector into a female receptor and they can spark.....I've seen them a
rcing .....put your head in the sand and ignore it at your peril. The reas
on I had three examples of molten connector assembly speaks volumes, not wi
thstanding the original "posting on subject" reported the same issue. In
test conditions the connectors may be adequately rated but subject them to
vibration and that rating is obviously open to question, in other words "th
ey are shit".

the power delivery spades which only have knife edge contact area . Some f
orm of screw clamp connectors would generate less heat from arcing , which
in turn would remove radio interference and potential for fire.

he AC scale, suspect a blown diode inside the alternator or possibly bad br
ushes. Remember, the alternator is only supposed to output DC voltage. This
isn=99t a perfect test, but it is quick and easy. A ripple meter is
an even better way to check stator and diode condition, but most amateur bu
ilders will not have one in their toolbox.
