Thank you Mark
I do appreciate your suggestions.
It is still the same issue. All you've demonstrated is that it may be intermittent. The issue remains that the starter motor is not getting energized. It is possible that you "jiggled" something - wiring or relay - when you took the gas tank off that temporarily made a bad connection good. Hoping for the best, this might suggest the issue is the relay or its wiring. If you do not know how to check the relay for operaton or how to check the wiring for continuity beyond ensuring that all your wiring harness connections are clean and tight (if you have not done that, then do so), then the only simple option you have is to buy a new relay and see if that solves the problem. In reality, someone with a multi-meter who knows what they are doing should be able to narrow-down this problem, may be even solve it, in a few minutes...
This is what I have done. after I took the tank off I hit the starter button to listen for the click.
The engine started for a brief moment. Then I hit the starter button again and the engine did not
turn over. .
With all fuses good, if the motor is not cranking then the issue is starter motor related.
If there's no significant clunk type noise from the starter motor when you hit the starter button then the starter motor solenoid is either faulty or is not getting energized.
The starter motor solenoid is energized via a relay located under the gas tank. It may be that relay making the click you report when the you hit the starter button (should be light metalic click).
Even if you hear a click for this relay it may be faulty, but it's easy to check with a multimeter or test light. If that's beyond your electical troubleshooting skills then you either need to find someone who can do this for you, or just start replacing parts, in the hope that the iussue is a component failure and not a something wrong in the wiring, until you solve the problem.
The under tank relay is easy and inexpensive to replace. Starter motor and related solenoid is more wrenching and more expense.
Thank you for your reply and ideas.
When I press the started button you are correct the click I hear is under the tank.
It is just one click.
Yes I would like some help trouble shoot the problem.
Airheads are pretty simple. Here’s a few ideas. Not sure what you mean by "one click from the button." When you press the starter button you should at least hear the starter relay under the gas tank "clicking" (it’s a typical relay light clicking noise). If you hear that and a metallic "thunk" from the area around the top of the engine (you might want to take the gas tank off to be sure to isolate any noises) then the starter motor solenoid is being actuated, but either the contacts that the solenoid makes are not being made, the starter motor has failed, the heavy-duty wiring to the starter motor has failed, or the engine ground has failed. If you get a combined "thunk" and whiring noise, then you may have a ring gear or starter motor gear issue (given it's a 47 year old bike then that is a possibility). Reach out if you want someone to help you troubleshoot.
The problem is simple. I push the started button..one click from the button..nothing. Battery is new, and at 100%
I replaced 2 stressed fuses (white) no results.
I tested the coils.......1.4 and 1.5..........
Lights work signals ect.
