And how many volts are you getting at idle compared to higher RPMs?
There is enough good in the worst of us and enough bad in the best of us that it does not behoove any of us to criticize the rest of us.

How do I determine how many volts its generating? Where do I test? Thanks.

Ultimately you need to have alternator output voltage reaching the battery, or within .5 volts or so. If you are losing 2.0 or more volts between the alternator and the battery, there is a bad connection which will cause more problems later. The alternator should be putting out 13.5 to 14.5 volts. | | |
