    So I suspect I smoked something in the charging circuit last fall, could be the regulator or it could be the armature.

    It's probably the armature. :(

    There's a couple of ways I could test it but the easiest is with a growler so I took a chance and snagged the cheapest one I could find on ebay.

    Purdy ain't it? OK obviously old & a bit grubby.

    Well grubby ain't the word, what I thought was a black growler turned out to be an extremely grubby growler. Turns out it was actually green under all the shmutz. o_O

    I'd say it's been through a fire but it's more likely it's been through a couple.:sneak: Been dropped more than once or twice as well.


    OK it did actually work but I couldn't bear to leave it in that shape so the tear down commences. It was *almost* as grubby inside.

    To say the wiring was roached would be the understatement of the year. :rolleyes:

    To aid in re-assembly I did a wiring diagram-

    Notice anything interesting? :shock:

    Everything got stripped out. I didn't bother trying to clean to case halves thy just went in the sand blaster & got shot till all the grub was gone, & it wasn't easy getting rid of it. I beat the case halves back into some semblance of straight & it's re-assembly time.

    I won't go into the nightmares I had with the hammer tone paint job or the meter either- let's just say in both cases the 4th time is the charm. But eventually I got it all snazzed up to an acceptable standard.

    Cleaner? I replaced all the coil lead sheaths and wiring with the exception of the power cord that got a new, polarized, plug. :) Note the colour of said power cord after cleaning & compare it to the first pic in the post above- I was shocked, umm, "Surprised" when I started to clean the red paint spots off of it & found it was the cord that was red o_O


    Re-assembly was a bit of a challenge, things are still bent more than I thought but it did, eventually, fit together.

    Still some adjustments to be done but for now it's good enough.


    Testing:

    Shorts-

    Growler_short_test_1_sm.jpg


    Passed OK :D


    Windings-

    Growler_output_test_sm.jpg

    Passed OK :D


    Given the original wiring's capacity to provide a, umm, "Surprise" I did make a change to it-

    Now with a LED replacement bulb the "short" current is ~ 17 - 18 mA vs. the 300+ it would have been with the extremely grubby 40 watter incandescent it came with. In fact I can grab both probes with noting more than a barely there tingle-

    Actual flow as measured through my thumb to my little pinky is is in the microamp range.

    Would I try this in the shower?

    Hell No.

    But it's a lot safer than it was :)


    I'm pleased to report that my spare tests out perfectly, or at least equally good or bad on all windings. Now after I get around to testing my suspect armature I can put the growler up on the shelf & never touch it again :D

    I was able to pull & test my genny this weekend. :)



    Unfortunately there's nothing wrong with it :(

    Next weekend- The Regulator.

    I though growlers were supposed to be full of delicious beer? :susp:

    Used those in Auto mechanics class at community college. Pretty cool. You saved some history there for sure. I like old tools that are useful.

    That looks like exactly the same coil mine has. :susp:

    Looks like 73 CJ5 has a growler in his collection of machine tools (see “Engine Tooling”).

    I regret not grabbing the virtually new growler from work when they were liquidating stuff. Only have so much room though.
