John Deere 2650 wiring diagram

[Scorpasia]

Hello
I have a 2650 and the electrics appear to have a mind of their own. When I turn on either headlights, work lights or sidelights something other than what I wanted comes on or nothing happens...

Obviously need to look at the electrics but cannot find a wiring diagram. Can anybody help me please.

Thank you

Would suggest you check all the earth's some strange thing's can happen when they start to go bad..............

Thank you. I will get that looked at promptly. Saying that, there are 2 batteries and when I had to change them recently there was a earth battery terminal, unattached, underneath the cab steps. As both batteries were connected properly I did not take any notice of this. I have not looked further into this...any suggestion. It could be an old earth terminal and totally redundant, again I will check this out too.

Appreciate the help but a wiring diagram would still be useful for the future.

The main electrical issues on 50 series are usually caused by either-
1 - the contacts on the main electric plug on the front of the cab just below the bonnet.
2 - the fuse card either not inserted correctly or corroded.
3 - dry/cracked solder joints in the dash, this is very common on 50 series due to age. If it’s never had the dash cards re-soldered it well worth checking.

Thank you. I have a friend who is a capable motor electrician. I will get him to check these things out.

Anybody got a diagram for the 4wd gears on the floor

Perhaps swap the key switch. It can do weird things.

Anybody Abel to take a photo of solenoid on a 2650 4wd or know what wires are used

I had to replace the ignition switch assembly because everything was going daft.
