The STATOR is
an important part of the electrical system, both from an ignition
and charging aspect. it can cause any number of problems including
powerpack failures, dead batteries, intermittent and weak spark.
you suspect the stator may be a cause of electrical problems,
take a closer look. Is there any discoloration of the potting
compound? Cracks? Drips hanging off? Pitchlike liquid leaking
out and running down the block? If any of the above symptoms
are evident, toss it: EVEN IF THE ELECTRICAL VALUES ARE CORRECT,
Be sure that the rectifier or rectifier/regulator
is in good order as well, if it's bad it could cause a repeat
failure. Also be sure the battery terminals are CLEAN and TIGHT.
Loose terminals kill stators fast. If you have wing nuts on the
terminals, replace them with a couple of elastic self-locking
nuts. Be sure to OPEN the terminal before you put it on the battery post, THEN tighten it until it's snug after it's all the way down. Pounding a closed terminal down on to the post will likely not stay on permanently, and may damage the battery post and/or the terminal.
