Introduction
The problem that is identified below does not have a known permanent solution. Until a permanent solution is known, use the solution that is identified below. Problem
Illustration 1 g01290408
The "B+" terminal on the front of the lower starter solenoid (1) may be loose or separated from the solenoid. The cause of this failure is currently under investigation.Solution
In warm weather, a D11R may start with only one functional starter. It may not be apparent that one starter has a failed or loose connection.If inspection reveals a loose or separated terminal replace the solenoid with the current parts until a permanent solution is determined. This will avoid any dead shorts or arcing of electrical components that might result in damage to surrounding components.
