I am not too good with electrical stuff.
Dodge 318 motor; either belts or alternator is squealing on startup.
Squeal is very loud and intermittent. When squeal is happening, alternator gauge bottoms at full charge, then when gauge returns to more normal setting, squeal goes away. IOW: squeal-->gauge bottoms max charge, no squeal--->gauge returns to more or less normal, midrange indication. Gauge and squeal vacillate till engine warms up and gauge returns to normal and squeal goes away.
Is this bad bearing? belts out of alignment? bad voltage regulator? bad alternator? Which?
Thanks for any good help.
