Another Starting Question

[fishfrank]

DK40SE: for the past 6 months I have been starting it by bypassing at the starter with a screwdriver. When you try the key it just makes a “click” sound. I have been too cheap to buy a new key switch until today but to my surprise it made no difference with the new switch. Fires right up with the screwdriver at the starter. What should I check or replace next?

I would look closely at the starter relay. This was posted by K0UA, another member, in another thread.

Hope this helps! Good luck!

Jumping with screwdriver would take ground out of the equation right?

 

[K5lwq]

Jumping with a screwdriver would indicate he has a good ground and a good power connection to the starter.

Not knowing what posts on the starter he is shorting across, I can only assume he is taking power to the solenoid indicating it is working. That is why I suggested the relay as a possible issue.

I’m guessing the low amperage wire going to the solenoid is the problem.

I have a couple of things to look at on my next days off. Thanks guys.

Check for fusible links.

I don't know about Kioti in particular, but Branson uses some fusible links for the starter and some other applications.

Here is an example:

A bad start relay is a common cause of these symptoms. This is a common automotive relay; special Kioti part not needed. There are three relays on the "firewall". Two of these relays are the same (start relay and stop relay). The third relay (glow plugs) has a higher current rating.

When you try the key it just makes a “click” sound.

I would assume the "click" you are hearing is the starter solenoid cycling but not making the connection between the positive battery cable and the starter motor. Sounds like you need a solenoid. If it is a light click from where the relays are...then a relay may be the culprit. Is the small wire on the solenoid getting power?

 

[ritcheyvs]

The distinct clack (when turning the key to ON) is the stop solenoid retracting. The start solenoid is energized then the key is turned to start; it's not very loud.

As a test, you can swap connectors between the two similar relays. If the engine cranks with the relays swapped (but won't start) That's good evidence of a bad start relay.

Starter relay! Cranks right up now. Thank you so much!

 

[ritcheyvs]

I appreciate the feedback; thanks.

I have learned much about these older (mechanical fuel injection) models from such feedback (plus my own wrenching and the manuals). But I plead complete ignorance when it comes to the common-rail computer-controlled stuff.

Glad you got it going! Thanks for following up! :thumbsup:

if the fuseable link was inline somewhere before the starter there would be no click.
most fuseable links come directly off the battery or positive starter post to feed the fuses.
you would also have other items not working
