I've got an alternator that occasionally shows on a Garmin EIS a high alternator output on the right side. It shows up for a couple of seconds and then goes back down to normal. It does that once or twice per flight hour. I looked at the connections on the alternator and I noticed some nuts that were wedging the connection on the alternator. It didn't seem like a great way to connect it but it would work. I think this might be a causing the strange alternator outputs. These outputs that go high are at all power settings. Can anyone confirm the connector and nut setup is as designed?
