Customer Question
My 870 will not...

My 870 will not start. I turn the ignition, it clicks then lights go out, nothing else. I installed a new battery, new fuses, cleaned terminals and reinstalled ground wire after cleaning connections.

Mechanic's Assistant: What is the complete model and serial number of your machine?

1998 John Deere 870, I do not have the serial number here.

Mechanic's Assistant: Sometimes things that you think will be really complicated end up being easy to fix. The Heavy Equipment Mechanic I'm going to connect you with knows all the tricks and shortcuts.

Thanks.

Mechanic's Assistant: Anything else you want the agriculture mechanic to know before I connect you?

THe machine has 1800 hours with regular maintenance,

Hi,let's see if we can work together to get to the root of your problem! will try my best to help!

Can you rotate the engine using a wrench or turning the fan blade by hand? If so, engine is not seized, and should turn with starter. You say you get a click when you turn key to start? Is the click at he starter solenoid area? Do you have a voltmeter to check the battery voltage when you turn key to start? Does the voltage drop ? If it does, the starter may be bad, or stuck in the flywheel.

The click is at the switch. It clicks and all power goes away. Emergency flashers go off. I have to wait an hour before the three ref lights come on again.I'm not at home or I would call you.

When you get back to tractor, check battery voltage before turning the switch, should be above 13 volts if fully charged, then turn key to start, what does voltage drop to? When was tractor last started? Next I would try jumping the starter solenoid, from the battery cable terminal, to the single wire switch terminal, to see if starter will turn engine, this is quick test of battery, cables, starter solenoid and starter.
