So I finished the narrow belt conversion and changeover to alternator. Took
it for a few runs and need to address a couple of points:
1. The belt squeals sometimes on initial throttle application. I tightened
it up (not too much) so I have about 1/2 play on the long leg, but no
improvement as it still occasionally does it. I don't want to tighten it any
more. The crank and water pump pulleys are aluminum and the alternator one
is steel. I'm hoping that it will bed in over time. Any thoughts?
2. When driving it last night, I noticed that the ignition light would
gently glow at all RPMs. The more load I put on it, low beams to high beams
then turn on heater fan, resulted in it glowing slightly brighter
(obviously). I could only occasionally see my voltmeter, but it was always
14V and the lights weren't dimming at all. It suggests that it was kicking
out a reasonable amount of juice. This morning I hooked up my multi-meter to
the battery and compared it to the car voltmeter:
- engine off, auxiliary position on the key - both read very close to each
other.
- engine on, RPM about 600 - multi-meter read about 12.5 while car voltmeter
read about 11.5.
- engine on, RPM >1000 - both read very close.
- engine on, RPM >1000, but with extra load such as lights or heater fan -
multi-meter read about 14.5 while car voltmeter was in the 13s and slowly
dropping.
I followed the instructions on VTR (option 1) with the exception that I ran
a heavy duty cable from the alternator output to the battery cable post on
the starter solenoid instead of using the original main generator feed wire.
