[Jomatra]

Dear Tom and Chris:

I have had some pressing issues that demanded my attention, so I am just getting back to you. Today I went to the boat with the intention of troubleshooting the tachometer problems. When I attempted to start the engines, they would turn over but would not start. In the process, I learned that the prestart heater was not functioning; even though the switch checked out o.k. When overriding and getting the heater working, the engine would start and continue to run until release of the "Start" position of the ignition switch, which removed power from the relay and caused the engines to stall. This is identical on both engines. I only have schematics for the OEM portion of the vessel; no information whatsoever on the Cummins 6BTA5.9 m3 engines. The ignition switches checked out o.k. I reset all of the circuit breakers that I am aware of and the problem persists. I hired an electrician and a diesel mechanic check out the problem and they were not successful at locating the problem and require a schematic that continues from where the OEM leaves off and the engine starts. There appears to be something (perhaps a fuse) between the two and we have no way of knowing where it is at without the laborious task of attempting to follow it all the way back. I have placed a call to Tiara today and left a message but have not received a response. I have also contacted Cummins to inquire of them if they have schematics and they informed me that this would be the responsibility of the OEM manufacturer?

The batteries that were installed, are identical to the ones that were replaced (wet cell or lead acid). This could explain the charging variance. I would appreciate your thoughts, ideas or suggestions while I await response from Tiara.

Thanks, John
