    Just when I had the new Andrews coil bolted in, and the top connector hooked up to the ignition, I started tightening the bottom nut and . . . snap! Off goes the brass threaded post. Dang! I wonder if I could drill into the end of the coil and insert a new threaded rod or am I buggared?

    okay, fellas, I soldered it. Hope it holds. Thanks. Oops - forgot to put a male/female disconnect on it . . . oh, well . . .
    I started it up and it works. For now.

    No disconnect. Just becomes a point to fail

    just thought of him soldering on a bench and the installing it on the bike thats why i said connector . it is another drop in current as it starts to get old . but there is some good weather pack connectors out there . i use them all the time on builds in the shop no problems. quick change out if the part fails . glad you got it running

    It was a good soldering job, too. Not cold and gobby. I learned how to solder years ago when I used to build Heathkits. Built a few recievers and amps in those days for fun and profit.

    nothing worse than a cold solder joint . drives a auto tech crazy ! you cant imagine how many ecm we had in the early 90 s . that had colder solder joints on the boards . drove us crazy trying to find out if it was the part or wiring !

    I agree,
    I think when Hotroadking said "No disconnect. Just becomes a point to fail" ment that a solid connection is not good, it'll become bridle with heat and time and break off, JMO
    if you don't think it is tight enough use a double nut or locktite. I think it should be a nut, then connection and another nut.

    "Heathkit" wow! Haven't heard that word in many years. I learned soldering building brass tube chasis for slot cars! Then Dynaco amps & tuners.

    Lots of good connectors that are weathertite and sealed. Used many on my boat for the electronics I installed, BUT, I would replace that coil soon like they said.

    I'd start shopping for a new coil.
    That soldered connector will prolly break off especially on a rigid shovelhead bike.
    If and when it does break you'll be stranded and calling for a tow.
    I've been there and done that.

    Soldered one on Dougs RK from Hell, the valdez, it's tossed more parts, broke more crap and leaked more oil than exxon.

    One of the post broke, soldered it on, been on 5 years without a problem
    in fact it's the only thing on the dang bike that hasn't fallen off....

    You're talking about a road king not a rigid frame solid mounted shovelhead, correct? Big difference in vibration.
    Hopefully the solder connection will hold but I personally would not trust it.
    Because of a bad electrical connection I've broken down and had to push my 650 lb bike 2 miles up and down the road in the dark.
    I ain't going out like that ever again.
    And a tow truck will prolly cost about $150.

    There's always duct tape - it'll get me home. And yes, I do carry a small amount in my tool bag!
    Saving nearly $80 is big right now. I built my scooter mostly with my S.S. checks . . .

    I do have an idea for a more permanent repair: drill and tap out a hole in the stud and screw in a threaded rod using epoxy to lock it in. I'm guessing no more than a quarter of an inch deep, making sure there's a solid electrical connection at the bottom of the hole.

    Okay, so I decided to unsolder the connector from the coil. Took it off and drilled a 7/32" deep hole into the stud. I was afraid to go any further as I could see the end of the wire. Tapped it out with a flat bottom tap and screwed the machine screw down using super glue to lock it in. Boys, it's in there for life. I cut the end of the screw off and put the coil back on the bike. Started it up and it ran perfectly. I think this is as good a repair as one could get under the circumstances.:cool:
