Re: Can you pull battery cable
Don't do this!
To test the alternator measure the battery voltage with engine off, then
with engine running at cruising speed (say 2000 RPM). You should see the
voltage increasing by about 1 Volt. The voltage should not drop much from
this level when you add load (headlights, A/C).
If you don't have a voltmeter, buy one. It will be a lot cheaper than
repairing the damage caused by disconnecting the battery.
