underscore Well-known member Aug 3, 2015 #2 Have you confirmed the charge is getting from the alt to the battery (it battery reading 14V while running)? The 100A charge fuse might be bad.

underscore Well-known member Aug 3, 2015 #4 Yeah when running the battery should be at the same voltage as the alternator output. Alternately you can measure the resistance between the battery positive and the alternator output, it should be a short between them.
