John Deere 5105 no electrical power

[coyote77]

I have a 5105 John Deere, I have a problem with the electrical sys. I have no electric , I replaced battery, now key switch, but still have no lights or power of any kind. Real confussed. Oh I replaced every fuse in the fuse block too but still nothing. Hope someone has an idea.

I moved your post to the John Deere Owning and Operating section. Hopefully you should get some answers here.

Hi Coyote77, welcome.

You may need to locate some master fuses/fusible links - they are sometimes buried in a harness somewhere - you need a shop manual, or access to somebody that knows that harness well, to locate these quickly.

Good Luck,

Rgds, D.

Re: coyote77

Thanks I'll give it a look and let ya know what I found.

As suggested already take a look at the fuse link. Attached is a picture from JDparts what it looks like. It will be under the hood. On my 5210 which is similar to your tractor it is on the left side above the starter.

Did anything happen before the problem started?

Thank you, I checked the fuse link , it is intact . I have power to the ignition switch when the switch is unplugged. That seems strange to me but when plugged in there is no power. Thanks again.

I was backing up after just starting it. I had drained the water from fuel filter but forgot to prime the filter. It died so to save time I used starting spray . It then turned once an made a hard knock an when I hit the key again it blew a 25 amp fuse so I replaced all fuse's but still won't start an have no lights etc. Put in new battery also.

I also put in a new starter switch. Checked to see if motor was free. I turned it by hand it is free.

That's a typical symptom of a faulty battery ground connection
