DK40 SE no start, no display, no lights, etc

[tophawk]

Hello I am new to the forum so excuse me if I missed a previous thread on my issue.

Let me start with saying I love my 2007 Kioti DK40SE. It has until now only had to have a ignition switch and battery change (plus of course regular maintenance of oils, and fluids) since I bought it brand. it has about 400 hr on it now. A few weeks ago I had a starting issue where it would not start. Thinking the battery was dead because I had a display but no start I took it off to charge it and found out it had a full charge. I reinstalled the battery ( cleaning the terminals too) and it ran like a champ being started daily until a few days ago when my wife went to start it and it didn't. So I told her check the battery and all connections. Well she was getting a display and then slowly everything quit... no start, no display, no clicks, no lights -headlights, turn signals, hazards. I ordered a new ignition switch (even though last time I replaced the switch it was just because it was having issues with staying running because switch innards were loose). because it seemed likely candidate for all to fail. Well that was not it. Soooo... I am requesting help and knowledge since I have no service manual or schematics.

Here is what I have done. Replaced the ignition switch; cleaned all electric contacts or disconnected plugs and reinserted them; Swapped the two relays; disconnected/ reconnected display unit in engine compartment; replaced battery; cleaned and checked fuses next to parking brake; realized that if I have the ignition off I get horn to "weakly and momentarily" honk and that I get a buzz when I try turn signals or hazard on but can not seem to figure out where it is buzzing (sounds like behind the display console.

I know this is a big complicated issue so ANY ideas I am up for. I need this running ASAP and the nearest dealer is 200 miles away.
thanks in advance.

You said you cleaned the contacts, but did you take the grounds off the frame, clean, and reconnect?
Grounds are notorious for becoming corroded. The ground wire itself (under the insulation) could be bad too.
You could try to use a "jumper" for the ground to see if it makes any difference.

Is it a new battery? Sometimes they are 'bad' and not taking a full charge. Might try to load test it and put it on a charger..... might help....

Good luck, keep us posted.

take a volt meter and start checking till you don't find voltage

I took the battery from my diesel truck (barely fit in so large) which I tested and charged just incase. load tested and it was good. Didn't do the grounds for corrosion except the battery cabling and the relays under hood mounts (just in case since I dont have schematics to show how they work). I will look for other grounds but it has to be something that connects everything to the battery/ electric system.

I did it for the start system before but I will check at fuse block and recheck all the way to starter again just incase I missed something.

unbelievably it started raining in the Nevada desert again today so my voltage checks and ground checks will have to wait for now. I will post tomorrow to let you know how that all goes along with putting the new starter I ordered before it went completely dead. Who knows the starter could be the drain when the key is turned on. thank you so much for the help and input.

starters don't cause drain, you would hear the solenoid buzzing if it was engaging, I can also guarantee you the starter is not your issue.

okay, I changed starter and of course that was not issue. There is 10v at starter not 12v. I also have no or very little voltage at the fuses. The fusible links are good. All grounds and relays (in engine and under dash) have been disconnected and reconnected. I am now in dire need of a wiring diagram to chase the voltage from battery to fuseblock (there must be something in between) I am wondering what the twin relay actually does because that sounds interesting. so if anyone has a link to the DK40SE wiring diagrams or what the twin relay (actually what all relays) do I would be very grateful.
