Howdy.....I'm trying to see if it's the starter or solenoid:confused:. I want to jump straight from the battery. My understanding is:

-a good battery
-leave everything connected as normal
-ground to the power head
-touch hot jumper from battery to the red/positive post on the starter

I assume sparks will fly:eek:. I'm only doing this to see if the starter will function. It won't with the key.

Is this correct?

Thanks for the help.....

That's the way to do it. Or you could check the system with a test light or volt meter, no sparks that way.

That would work but I would connect the jumper to the starter then touch the other end to the battery. That way you won't screw up the threads on the starter. But before you do that have you checked the 20 amp fuse under the cowling? If that is blown the starter will not work. Also you can check the solenoid by jumping 12V to the small lug on it. I forget what color that small wire is but its not the black one.

Gee, why not connect a jumper cable from the red battery cable on the starter solenoid to the other large cable on the opposite side of the solenoid that runs to the starter? If the starter spins, the trouble is a bad solenoid or solenoid power from the ign key. If you are just checking starter operation, leave the ign key off.

From what I did today, I believe it must be the starter. Here's why:

-battery checked out strong at Autozone.
-replaced cables from battery to solenoid/starter.
-disconnected every connection related to the battery/solenoid/starter and made them shiny.
-this resulted in no change, just the same solenoid click.

Broke out the meter and this is what I found:

-12.7v on the RH solenoid post, no key. 12.7 on the LH post (hot to the starter) when the key is turned all the way to the right. The solenoid clicks once.
-0.0v on both small posts without the key. 11.8v on the RH post w/key. 0.04v on the LH post w/key.

So I've got full power to the starter, but it does nothing, even with tapping. Am I right in concluding it's the starter? Or is there something else?

Sounds like you have 12.7 volts to the starter when the solenoid is engaged, you need a starter, or repair the one you have.
