A newly designed and better insulated wiring harness is now available for 840 tractors with 24 volt electric cranking motor. This harness incorporates a non-metallic asphalt saturated loom. It has been shortened to provide more direct connection to electrical units.

This new wiring harness will correct electrical failures due to excessive vibration which causes the harness to wear through at the attaching clips or other points where contact is made with the tractor. Such conditions could result in failure of regulator, generator or at least the harness itself.

Order the new harness by Part No. AR21861R which replaces the old AR21576R assembly.
