Motorcycle Repair: 1976 flh starter relay, amp circuit breaker, starter solenoid

Question
Hi Mike, Hope you had a good break.  I've written to you before about my electric start problems on my 1976 flh.  I wanted to know why/if it is necessary to wire in the starter relay at all.  If I just wired my hot wire from the starter button, through a 15 amp circuit breaker directly to the small terminal to the solenoid and all the other wiring stays the same, would that work? If my starter voltage drop is within spec's and I have a new solenoid, My battery is good, etc. shouldn't this work?  I know that a bad battery, or even one bad cell can possibly cause the "running on" problem.  I've seen a gizmo advertised that goes right over the solenoid, like a "cap".  Key on, and push the cap back and it fires up.  Like jumping the solenoid with a screwdriver, I guess?  My square type relay tests good (.08 OHMS) from the constant hot terminal (#87) on the relay, through to the solenoid terminal (#30), and "0" OHMS across the starter button wire terminal (#85) to the to grounded terminal on the opposite side of the relay (#86).  So, as I understand it, the hot lead from the handlebar starter button "triggers" the relay to send 12V voltage (via a 15 AMP circuit breaker) to the ignition terminal on the solenoid (the small one).  The problem in the past is that the starter continues to "run on" unless I disconnect the battery ground ( keep it hooked up with a vise grip for quick release).   I know my handlebar switch is good and not sticking or shorting.  I once did come across that the ground to the relay was not grounding,"running on"?  Anyway this has been a drawn out process since my health issues only allows me to work on it in spurts, often with months between work sessions.  So, once again I appeal to your expertise about this situation.  

Answer
The relay maintains 12 volts to the starter solenoid while you have a voltage drop when you hit the starter button. the voltage drop is from the starter drawing so much current. If the starter continues to run, its a relay problem, but a starter solenoid problem. When it keeps running the contact in the solenoid is sticking. Have you replaced the solenoid spring?
