    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

77 GS400 more ignition point troubles

1) with power off, and points disconnected from everything, use the ohmeter. function of a multitester... One lead to where the power comes in (the insulated side) the other to ground( the base plate) rotate the engine with a wrench so the points open and close and the meter shows infinite resistance (open poiints) or no resistance (closed).

2) or with power on, get a 12v lightbulb with wires attached (a turn signal with clips on the wire ends is handy) and put it in series ...either, connect it in place of the coil OR "beside it","in parallel", to the same connections the coil is using... Rotate engine with a wrench-it should go off when points open,on when they are closed.

3)or, with power on, use a voltmeter. Connect one probe to where the coil connects to + the other probe to where the coil connects to points (the insulated side) voltmeter reading will change radically as the points open and close.(This is a "voltage drop" test )
 
I still think the points, both the body and spring part are permanently earthed. The screw and nut holding the spring and fibre washers. Put a different set of points on right side, even old ones and try checking again.
 
^^that's what I am trying to establish as a first suspect. Gotta start somewhere. Then, "up the line" to coil's power supply. 2),3) above will also show if there is power to the coil...by simply grounding the bulb or negative probe.
 
I will try all of this and report back. Thank you for your detailed writeup!
