    Cat 305.5e not charging

    I got the machine sorted today and it’s now charging. The exciter wire was in the wrong place, moved the pin over to the middle of the plug and that did the trick. Thank you all for all the help!! Really appreciate it!

    Shout out to all you guys for the help I really appreciate it. Feel like I’m actually getting somewhere now. Was getting really discouraged. I’ll try it out tomorrow as it’s 9:30pm where I am (Cayman Islands). I’ll keep y’all updated

    At this point that sounds like the best solution. Not by the machine at this time so not sure about the markings, at least the old alternator doesn’t have any markings. Found this on the website I ordered the alternator from. I think you’re spot on with the terminals. Correct me if I’m wrong.

    Possibly Still doesn’t make sense to me. It ran the battery all the way down until the screen went black and the machine couldn’t move. Turned it off and Wouldn’t start back until i put another battery in.

    Noted. Best picture I have on hand. Not sure exactly how he tested it because I wasn’t there my brother was. There’s only one wire in that plug so not sure how it could be connected wrong. When I turned the key on and tested the plug I got 12v.
