I didn't mention that I had tried a helper relay. It required 10V to keep it closed (not something that was not mentioned in the specs), and when the solenoid was activated, the voltage to the relay dropped below 10 and so it opened, and kept doing that same close/open thing as long as the key was in start position. The other thing I didn't mention was that I also replaced the ignition switch, which is another place with contacts that can be a source of increased resistance/reduced voltage. Considering that the original wiring and connections on the GR worked just fine, and that poor connections are the only things that will lower the voltage, there should be no necessity for the relay if the connections are in good shape. But that it worked for you is great.
