The gauge hasn't moved in a bit. Then I broke the ear on my alternator. Bought a lifetime from auto zone. Didn't know it was shipped to China for a rebuild. Grrr. Had issues when a VR lead broke. Replaced that. Alt was putting out .01 more than batt voltage with field grounded. Replaced alt. New vr from China. So ordered a MP USA unit. Just was wondering, if the gauge being dead would affect things...and would just jumping it would alleviate any issues? And do I need to use another volt gauge? Where is a good source for a new factory one?
