    And I'll bet you rearranged the push buttons on your radio to: BCIKU too. (For those of you who are too young, that stands for "Baby Can I Kiss U".

    On my '55 Century, I used to snap an inch off of a hack saw blade, remove one of the screws secuing the dome light switch, and install the hack saw blade so I could move it and it would hold the button in so I could leave the door open without the dome light coming on. :TU: Oh how I loved those extra wide, extra long front seats. :laugh:

    I am going to get in trouble here:Brow: If you want to keep the car stock,there is nothing wrong with keeping the generator
    If in fact,you do have a completelly dead battery you can bump start the car & it will start charging PLUS provide enough spark to power the coil.An alternator wont.

    That being said an alternator is better for modern day driving.:TU:

    I can build you a custom one or rebuild your generator,check my ad in the vendor section.:pp

    Question Jamie - the only reason I really want to ditch my generator is because the damn thing produces practically nothing at idle, in fact at idle my e-fan is drawing from the battery. Is that something you can tweak when you rebuild it, or is that just the nature of a generator?

    Just the nature of the beast.The way to cheat is to go to a smaller diameter pulley:Brow:
    I do that to a lot of tractor generators:TU:

    Not for high RPM motors though that use a bushing instead of a bearing on the rear of the gen.

    Might have to steal that idea, thanks :grin: !

    Follow up Andy,i bailed to check my e-bay auction:Dou: Saw your sig & figured i'd come back to comment more.

    What kind of amperage does your E-fan draw,some i've heard about draw 40-42 amps.The stock delco generator can do 32 amps at max output which is like 5K engine rpm,at idle your battery will go dead running a engine cooling fan.:rant:

    I think it's rated at 15 amps, 20 tops. The generator does fine at any speed off idle, but creeping around thru a show it definitely doesn't keep up. It hasn't been a problem thus far though, just annoying.

    I blew something up hot rodding around before putting the car away for winter. One good burnout and it just quit charging. Good thing I was right around the corner from home. Could I just have fried the voltage regulator? Or could I have fried the generator? Or did I fry something else?

    There would be no good reason to fry any part of the electrical system from a burnout....is your battery laying sideways,or fan belt gone?:laugh:

    Nope, everything was in tact. I'm pretty sure the belt was still there. I haven't seen the car since the beginning of September, but I'm pretty sure I would have noticed if it was missing.

    Or maybe I'm just that much of an idiot :laugh: !!!

    Many of us overlook the obvious:Dou: Check it out:TU:

    I'll check when I'm back home for Thanksgiving, but I'm pretty damn sure everything checked out. That's why it was soo puzzling to me. Any other thoughts, providing my dumbass isn't to blame :grin: ?

    As was previously mentioned, the only advantage of a generator over an alternator is that a generator will charge a good, but totally dead battery. An alternator requires voltage to the rotor in order to charge. BTW: (not that it matters much) Did you know that "Alternator" is a trademark of Chrysler?

    You should be able to use that one yes.

    And just to follow up with Jamie above, everything is hooked up and my belt is still intact. I even fired it up for a minute or two and had no juice. Thoughts?

    The older-style internal regulator GM "Delcotrons" are pretty much interchangeable. They do vary in output and pulley size. Air-conditioned Nailheads used a dual-groove pulley. The only significant difference in the GM alternators is where the wire harness plug is located. The rear half of the alternator may need to be "clocked" in order to plug ot into the wiring harness. This can be done by removing the four long screws that hold the halves together. Twist the back half to get the plug to the desired location. The stator must turn with the back half. DO NOT separate the halves any more then you absolutely have to, or you will pop the brushes out of their holder.
