843 BOBCAT SKID STEER NO POWER TO STARTER OR INSTRUMENT PANEL

[Dutch]

I'm Bryan, and I'm a new member of the forum. I bought a used Bobcat 843 Skid Steer with 54 HP 4-cylinder Perkins diesel that I have used less than a year when this problem occured. It is probably an early 80's model. I searched the forum for similar electrical problems and found RW's problem. My problem is similar to his. I have no electrical current to my starter or my instrument panel. I opened the rear engine compartment and found a small green electrical wire attached at one end and loose at the other end. So I fiddled around with the loose end of the wire and touched the loose end of it to the positive post of the battery and the solenoid clicked. Then, I went up to the cab, turned the key to the left for the glow plugs, and then turned the key to the right to start it, and no power. So again, I touched the loose end of the wire to the positive post of the battery and the solenoid clicked. I returned to cab to start it, this time turned the key to the right to bypass the glow plugs, and it started and I let it run for awhile. I turned it off and I tried starting it again, and I had no power to the key and no power to the instrument panel. So again I touched the end of the wire to the positive post of the battery, after doing this a number of times the solenoid would not click. So I replaced it with a new solenoid. After installing new solenoid, I checked both fuses on the control panel and they were good. I raised the cab ROPS and checked the connectors and found no bad wires. I took the battery out, added water to all cells, recharged the battery, cleaned the posts and cable connectors. In the process of removing and replacing the solenoid the attached end of the green electrical wire broke off and I didn't see where it broke off from. I now have a 12 inch green electrical wire disconnected from both ends and I don't know where this wire goes. I am back to square one, with no power to the starter and no power to the control panel, with a loose green electrical wire that has got to go somewhere to make connection so I have power again. If anyone out there has a similar model would you please check yours and tell me where the ends of this green electrical wire attach. I'm admittedly not saavy with electrical issues and I do not have an electrical meter. I 've attached pictures showing my hand holding the wire in the area above the battery, where I think it should go, but don't know where it attaches.

Can you get me a better picture? the one you posted is a little too small to see enough detail. Look up my profile and send me an email.
I wonder if you blew a fuse by powering the relay the way you did.
This setup os very simple, i just need to see the relay terminals a bit better to tell you what goes where.

What is the relay? I don't know what relay is. Is it the Solenoid you are talking about? Maybe these pictures will help. Is it the fuses on the instrument panel, or is there another fuse that you are referring to that may be blown? Let me know if these pictures clarify. If not I will send you better pictures to your email in your profile. Thank you for your help.

i had the same problem with my 643. it was a bad connection at the starter. they wear out after a while. disconnect the battery and put on new crimp connections on all of the wires. all of mine broke one by one in a few months time, should have just done them all at once.

Hey Taryn,
Thank you for your help. I fired it up! Turned the key to the left, had glow plugs, turned the key to the right, it started, panel good, ran for about 20 minutes and then died. It's done this to me before, I know it's a fuel problem, so I will start by removing the sending unit, removing the pickup screen, take the fuel tank out, flushing it out, but this will be a long process to make sure my lines are clean to the injectors. I will most likely need help later when this is done. Thank you this has helped me tremendously. I still haven't hooked up the 12 inch green wire with diode. I will have to figure this out later.
Thanks again, you have been a TREMENDOUS help!
Bryan

No worries, hopefully you will sort the fuel issue out easily. I emailed you a few things to check up on.
