PROBLEM

Show/hide table

The existing 2418368/">241-8368 Switch Assembly (Power Relay) can fail on certain D5R Track-Type Tractors, that set for a long period of time. An internal short on the switching side of the power relay may be the product of a conductive path created due to "migration" of copper material from the relays contact assembly to housing. Material migration can be accelerated by moisture.
