IMPORTANT:
When working on the electrical system, always disconnect the ground cable. This prevents damage from occurring.
If the starting motor does not function or operates sluggishly, the fault may lie not in the starting motor but in one of the causes suggested below:
-
Loose, dirty or corroded connections:
clean and tighten all connections.
-
Low battery tension:
check battery charge, if necessary replace battery.
|
-
Run down battery:
recharge battery.
-
Wrong engine oil viscosity:
use engine oil with specified viscosity.
-
Defective starter motor safety relay:
replace relay.
If the remedies suggested fail to correct the problem, contact your John Deere dealership. Have starter motor inspected by a specialist workshop once every year.
