With the battery fully charged (12.68 Volts) and a volt meter connected to the positive and negative battery posts, run engine at idle with no accessories on, voltage reading should be aprox 14.2.
Alternator is defective.
If your battery was dead and you jumped it to get it started and the gauge shows your not charging you need to replace the alternator.
From 13.5 to 16 volts.
From the alternator to the battery should be 14v
By buying a Chilton or Haynes manual and reading
I would suspect that the alternator is failing. Have it load tested at your local auto-parts store.
Not necessarily. There are a lot of factors that can keep you from reading 14 volts at the battery, such as corrosion in the cable from the alternator to the battery.
Connect a voltmeter across the battery terminals without engine running reading should be around 12.8 With engine running reading should be 13.8-14.2 if you are getting these numbers alternator is charging battery
Check to see if the alternator is working Connect a voltmeter to battery: Without engine running reading should be about 12.8 With engine running reading should be 13.8-14.2 If not bad alternator
60 Amperes. And the question is properly phrased, "How much Current Output should the G20's alternator have?". "Amps" is not a word.
Bad alternator?Check output with a voltmeter - without engine running battery reading (fully charged) should be around 12.8 With engine running reading should be 13.8-14.2 if not probably a bad alternator
Get a "multimeter" which is a device that measures many electrical currents and put the positive and negatives on the corisponding terminals of the alternator you should be getting a reading of 12 to 14 volts if this doesn't happen then your alternator is'nt working properly
