1. A faulty alternator is fairly easy to troubleshoot with a volt
meter. With the engine shut off, battery voltage should be 12 volts or
slightly higher. Start the engine and it should increase to 13.5 to 14.5
volts with the engine RPM around 1,000 or so. (If it doesn't, the alternator
is bad). Start turning on the electrical devices. The voltage should
maintain the same as it did before you turned them on. A marked drop in
voltage, even with the engine accellerating indicates a bad alternator.
2. A fully charged battery should read 12 volts or slightly higher
and maintain 10 volts while cranking the engine. If it doesn't and you know
it is charged, it is bad.
