Best start by saying that I've never owned a diesel, but I did work on them in the USN long ago. Here's my interpretation:
Parts # 6 are starting aids, which to me says they're 'choke' injectors. They're akin to the choke on an old carbed gas engine, used to give a richer mixture when starting. Part # 2 is a solenoid (operated) valve, probably energized on cold start and allowing fuel to flow to #6.
At a total guess, it's a generic solenoid valve, with several uses. The second terminal may be to allow for a ground wire when needed. Yours may not need a ground wire, since it may ground thru the mount or the metal line to the 'start aids'.
Check for continuity & resistance with a volt-ohm meter, measuring from the wired terminal to both the body of the solenoid & to unwired terminal. If I'm right, there'll be almost no resistance between the unwired terminal & the body, but there will be measurable resistance between the body & the wired terminal.
Good luck, both with it, and with following my gibberish... ;)
Jim, "The old expert, often wrong but never in doubt."
Your suggestion to check to see if it is grounded through the boby is a good one, thanks, will do, will also check to see if the wire that is connected goes hot when cranked outside in the cold.
A good guess. Parts #6 are intake air preheat units which inject a small amount of fuel supplied by the line via part #2. The electrical connectors to #6 ignite the fuel. Mine has the same setup and one of the #6 units was broken when I bought the unit in 04. Purchased a new one thru Cummins. This system is only active during the preheat or wait to start cycle. It is not unusual for a solenoid to have only one connector and the mounting threads supply the ground to complete the circuit.
The 325 engine was used in fire engine applications and to some MH manufacturers. I think it is a great engine and has been a reliable work horse in my bus.
I believe you are correct.
I just have to determine if a ground is needed and that is a simple test.
I will not be able to check until next week.
Thanks for your input, I am very encouraged by the 325 Cummins engine. all good news.
I love this quote "The 6CTA 8.3 (450 Diamond) is the most sought after marine diesel in both recreational and commercial markets" off of this site
