charging system help!!

Boy do I have a story to tell! It ended up being my altenator after all. When I was changing from one altenator to the other we were changing one brush holder because it was missing on the other alternator. So I decided to get the spare alternator checked and I put the brush holder on it and went and had it tested. It was missing an insulator on the brush holder we were changing :oops:which ended up being my problem from the get go! Thanks for all your help everyone with this silly problem! We are going cruising tonight and will not have to worry about getting home before dark.
