Hi all,
I have a 91 st1100 28 amp alternator. recently found the insulator going into the main fuse/starter relay melted so I replaced that wiring and added 4 new insulated terminals. What I am finding now is the charging system does not work with the headlamp fuse in. I have done a regulated voltage test - shows from 12.61-14.30 with the headlamp fuse out. as soon as the fuse completes the headlamp circuit it stops charging and will only run off the battery. Looking for some ideas - I am currently checking the wiring harness and grounds. Thanks.
