Bel, and Alternator woes
I installed my new Bel 615R last night. Wouldn't you know it -
ever since then, I haven't seen any cops! I'll let you know when I
finally get a legitimate test of the unit.
As for the alternator woes, I had similar problems a couple
months ago. You need to completely ignore channel 11 on the HVAC unit.
It is very misleading. In the Cadillacs, the voltage stays way above 14
volts all the time, even under fairly heavy loads. My channel 11 was
going down to 10 volts on high blower, which really upset me. I was
trying to figure out how to install a 140 amp alternator for a while! I
finally strung a long wire from the charging post behind the right
headlight adn put a Fluke voltmeter on it, and simultaneously put a
voltmeter directly on the battery (I removed the rear seat for a day.)
What I found was that even when many of the high-draw accessories
were on, the alternator was indeed putting out 14 volts! I found that
the big wire from the alternator to the battery typically dropped 0.1
volts, and channel 11 was still reading in the 10s with the blower on.
The only thing I can figure is that maybe channel 11 reads between the
blower and ground, so 14 - 10 = 4 volts, would be the voltage drop across
I had my alternator rebuilt by a reputable local shop for
$85.00. I also bought a new battery, but found out that it was faulty,
so I returned it, and now I am still on the original battery, which I
also think is worn out, but is working better than the new one I bought.
Crazy electrons... I'm glad I'm an ME, not a EE!
