    The only way, is to cut through the guess and by golly and use a methodical approach. RTFM! There aren't any shortcuts, at least until you reach a point where it's all memorized. You have to have a voltmeter, no way around it, and if measuring anything other than the charge voltage at the battery posts it really needs to be a needle type analog meter. A digital display is going to hork out on some of the tests when trying to test a mechanical voltage regulator.

    With the generator on the bench (or on the truck) there's some tests you can make, for example spinning it up with a drill and measuring output, on a Ford type for example by tying the ARM and ... is it the FLD or GND with a jumper wire together? See, I can't remember. On type A generator's it's different. Ya gotta have a manual or you'll roast something. Can also see if the generator will motor if 12 volts is applied. These aren't definitive tests but if the generator motors OK it should work.
     
  2. So the easy way to remember a straight 6 firing order is...15 is too young, 36 is too old and 24 is just right, old guy told me that back when I was 16 or so... could not figure out what was wrong with a 15 year old back then.... now that I'm 59 I can't see what would be wrong with a 36 year old...

    Just got the generator tested and works woohoo.


    Now waiting for truck to arrive and get the new volt regulator and put it in and polarize them both.

    Thanks,
    already past the firing order issue for a while now.

    "I told you so" is considered bad luck, so if I warn you ahead of time again that doesn't count right?

    Is this one of those blue cover regulator jobbies seen everywhere? Maybe it will work for a while, but that's not the way to bet. Good used or NOS is the only way to go if you insist on running a generator. The idea here too is to not roast your brand new generator, if it isn't already.

    It's the generator that is polarized not the regulator, just for information sake. Contrary to popular lore Polarizing is not necessary, for example, if the battery is replaced or simply disconnected, or even if the regulator itself is replaced.

    Replacing brushes, or anytime generator is disassembled and re-installed etc, that's different. If it has sat for a long, long time. Or dropped. Since the generator is polarized from the regulator itself that's probably the source of the confusion. Motoring the generator accomplishes the same thing btw.

    Oh ok, thank you.

    I'm not sure yet as to the regulator the one I pulled off the truck has a black cover/casing. I assume the new one should be the same.

    So I powered up the generator by using jumper from the positive side of battery to the post and negative side of batt to ground /stud hole on gen, and it spun up all the way and then touched the positive side to the other post on gen and it stopped it as supposed to.

    Hope that's the correct thing I'm supposed to do, if not I'm sure you'll tell Me I'm a bone head lol

    Anyway thank you

    The problem ain't you, it's the quality of reproduction replacement parts available today. You bought a voltmeter too right?? No way around this. Don't make it any more complicated than it already is.

    Yeah, they make cheap reproduction crap today, as when years/decades back they made QUALITY parts that lasted.

    Anyway, I tested everything multiple times and the system is charging and working properly again.
    (Or so it seemed at the time.)

    Well , s***!

    I got the generator and the regulator all setup and after jump starting the last couple days, still hasn't charged the battery it's self enough to not have to jump start.

    The regulator was polarized as instructions suggested, generator was setup correctly and test light shows a good output to charge the battery even at idle speed.

    So now what?!! Grrr
    Not happy!!

    Or am I jumping the gun and expecting it to charge too quickly?

    I dkn.....

    Charge battery using external charger to 100%, this will take hours or overnight at a slow rate if it's dead, as is likely. This is always good practice even if using an alternator. The charging system isn't designed to charge dead batteries, believe it or not.

    Need a voltmeter to do any sort of troubleshooting of a charging system.

    On another note, pulled gas tank and patched a leak I found.. Let it set a couple hours as JB weld instructed and filled it with water to check for any more leakage. So far all is well and sealed.

    Also fixed My gas gauge and got it working.

    So fixed 2 birds with one stone, so to speak.

    Ok, still having issue of these old split ring rims. I can not find anyone to work on them locally.
    I have seen other postings of people swapping out to comparable sized solid / straight (whichever is accurate) rims and keeping the same size.
    What is the comparable size to Mine?
    7.00 - 18" "dually"
    I am going to keep My original rims for restore at later time, however I need updated rims to drive on now.
    Thank you in advance

    What happens if you disconnect the wires on gas tank (fuel gauge) and reconnect them , but can't remember how they go?

    Would that cause fuel not to travel to fuel pump / engine?

    I've tried pouring gas in carb, it'll run til that gas is gone then dies.

    Just trying to figure out what's going on and why no start and run..

    No, you do not have an electric fuel pump on that truck. Take the inlet off at the fuel pump, and stick it in a container with some gas in it. Take the line to the carb off and stick it in an empty container. Crank engine and see if it is pumping gas into the container.

    On your wheels, have you tried a place that services tires on heavy equipment?

    I will try that and see what happens.

    I did pull the line off the fuel pump last night, and cranked it over using fuel I poured in carb,
    saw nothing and line is dry

    You either have a bad pump, a restricted fuel line, dirty tank or filter in the tank or an air leak making the pump suck air. Good luck:), Gary

    If you want to keep those wheels, you are going to have to go to a truck stop, or a place that services large tires to get them done. Big O and Walmart, nor most any other tire store is going to touch them.

    I was in a rush and forgot to connect the fuel line all the way.
    It started and drove down the road fine.

    Now I'm back to no charge to battery even though the regulator and generator are putting out current still no juice after only 30 min drive. .

    Going to auto store to buy a tester and see what is going on.

    I know of one place back in Zoocity, Mt. where I can get them service without issue.

    If I need to ship them, I very well may do just that.
    I would like to update the wheels to current times for daily use, however I need to know what size to get that will fit with clearance and no obstacles.

    I have heard either
    17.5
    19.5
    20
    Or 22.5 will fit but I don't know about what the width of the wheels need to be to fit My truck properly.

    I like the sound of the 20" and I am sure they make an 8 lug in each size. I am listening and open to suggesrions of anyone who may know.
    Thanks all

    Take your tape measure and measure your tires height and width. Then do the same on some dual wheel trucks and cube vans. I am sure you can find units that will work.

    Thanks, the only issue I have come across is that My wheels are 5.5 width, which works perfectly, and all modern wheels seem to be 6.5 width.

    Personally, I would find a set of 16 inchers and run those. That is what the 3600's came with, and 17.5's were optional. I would think the 16's would be the easiest to find, and Ford and Dodge will go on there also. Glad you got your fuel delivery issue sorted out, sounds like it was an easy fix ;) Now get the charging system figured out. Just curious, have you tried a different battery?

    Yes 2 different batteries same effect. Pulled neg battery terminal and died immediately.

    It started right after replaced old gen and voltage regulator.
    My wheels are 18's. And My truck is not a 3600, it is a 3800 1 ton.
    16's will not fit over My drums front or rear.

    This is the reason that the automakers switched to alternators. Generators are just too much of a hassle to keep working. You will have to learn to work on them or find someone who knows how. Most of the people who know them are retired. 1960 was about the time the switch to alternators was made. Generators and starters kept some shops in business but there are fewer around every year. The large scale chain stores can get them rebuilt cheaper and many of the local rebuilders don't install or service them on the vehicle. There are some stubborn people who still use them but they seldom work on others vehicle. A shop with mechanics that were born 20 years after generators were no longer used in vehicles aren't likely to have seen one, let alone worked on them.

    No worries. I've had to remind a couple others that it's a 3800 1 ton and not a 3/4 already lol
