The E-Stop 109-6507 switch may have been wiredincorrectly on the MPD Pilot House panels within the 257-7952 Panel Gp;249-6961 and 257-7948 MPD Pilot House panels. If the E-Stop is wired incorrectlyand the engine is running on the secondary ECM, the engine will not shutdown when the E-Stop button is depressed. The E-Stop may also not preventthe engine from starting up again, if a start signal is sent to the engine.It is estimated that this is a potential issueon 3500B marine engines that were shipped with MPD Pilot House Panels from18-MAR-05 through 21-DEC-05.AFFECTED PRODUCT

No parts needed.ACTION REQUIRED
The published 249-6960 Wiring Diagram (MPD PilotHouse) is correct. The contacts of the E-Stop need to be checked in orderto ensure that they agree with the published diagram. This check can bedone as follows:
Ensure that the E-Stop button is not depressed.
Check for resistance across terminals 13 and 14.
This should be a Normally Closed contact; thereforethere should be no resistance.
If there is resistance, then the E-Stopwiring does not agree with the published 249-6960. The contacts of theE-Stop must be rewired as follows:
The 111-1324 normally closed contact at terminals13 and 14 must be rewired to terminals 21 and 22 as shown below.
The 111-1323 normally open contact at terminals21 and 22 must be rewired to terminal 13 and 14 as shown below:
