Topic: Points Plate Setup

[CU2151]

I was in the middle of replacing my points/condensers and realized I should have done them one at a time.  Now I'm unsure of how to hook up the blue/yellow wires with the condensers at the points.  Does anyone have a pic of this setup? 

I'm guessing the condenser should be insulated from the blue/yellow wire so it only charges when the points are closed through the points and then discharges exactly when the points open, but I am terrible with electricity....

Actually, you connect a condensor connector to a blue or yellow wire, directly on the little points bolt. Just make sure that the connectors don't accidentally touch the points brackets or the points plate, or it will ground out the circuit and no sparks will result (it won't fry anything, it just won't run on that pair of cylinders).

The condensors charge when the points open, absorbing the little arc (somewhat) that kicks back from the coil at the moment the points first open. Then when the points close again, they dump this back out through the closed points, for the next cycle.

They are not really there to "charge up" for anything: rather they are there to absorb the unwanted kickback and harmlessly dump it out when it won't hurt anything.

Obviously, there are many more secrets about this, but at the simplest level, that's how they work.

And the blue wire on the left point set (1.4) with the yellow on the right (2.3)

This is the best description of WTF condensors do that i have ever heard. Thanks HondaMan!

If you squint just right at the parts diagram it actually shows the arrangement of the points connections fairly well.  The condensor's terminal is stacked directly against the points wire terminal, and both are insulated by the fiber washers from the point's bracket.  The bolt carries the current to the point's spring and from there to the point itself.



Here's what my 750's points connections look like.

Nice shots, Mystic! 

Can I use these in my book? 

[mystic_1]

For sure.  Lemme know if you want bigger copies.

Thanks, Mystic! Please drop me your name & address at my home e-mail: I'll give you credit as "Contributor" in the chapter. I'm writing the Electrical Chapter now, one of the last ones to be finished. I found a publisher last night that looks pretty good, who can make these books for less than $50. I'm getting jazzed, now: all the local publishers wanted more than $50 to print them, and I'm trying to keep the final price below that figure so people can actually afford to BUY one, when it's all done...

Email sent, HM.  I attached the high-res versions of the images to the email.
