When launching the boat this year the diesel refused to start. At first I thought the batteries were to low but the volt meter at the operator station showed enough voltage. It took awhile but I eventually realized the voltage wasn't dropping when I held the glow plugs on.

As I started tracing the glow plug circuit at the operator station and the diesel I found three different problems.

1. The glow plug solenoid, located on the motor by the fuel pump was dead. It can be checked by putting voltage to the small contacts on the front. If it doesn't activate it is bad. The new one was purchased from Kaufman Diesel for $17.13 ( Universal $37.29) and replaced the circuit breaker on the solenoid at the same time for $2.50 (Universal $22.33).

2. The starter button was beginning to stick and the rivets the hold the contacts on the rear were loose. It turned out to be corroded and was very difficult to remove. Kaufman's price for push button and boot was $6.05 (Catalina Direct $28.70). I was very happy to have discovered this while it was still working.

3. The 12 position connector strip inside the motor operator station was rusting. I replaced it also with one rated for 20 amps but would like to find a better one then I used.

I like to hear about these things myself and thought maybe some of would also. I think of my boat as fairly new but my 310 is a 2001 and even though it lives an easy life now on an inland lake it spent seven years on the east coast and was exposed to the salt life.

Good prices from Kaufman Diesel. Too bad they are in Ohio. I wonder if they would ship here?

Also, good find on the starter button. I will have to check mine out.

I would use a terminal block with ring connectors. Like this one from Blue Sea Systems (http://www.bluesea.com/products/2512/Terminal_Block_30A_-_12_Circuit).

Any idea what the pink wire is that isn't connected to anything?

I'll check that block out. I like that it is 30 amp. I haven't looked at the diagram yet to find the pink wire but it wasn't even stripped back.

Kaufman Diesel is very interesting. His first name is Merlin and he was born Amish. He lives in the heart of Ohio Amish country. He is a Kubota Dealer and makes his living servicing he says about 500 Amish Diesel generators. There was a time he worked on sailboat diesels on Lake Erie so he understands our needs. He has a website but all it has is his contact information. He may be willing to ship to you. I can email you his number if you want it.

Blowing 10/12 knots right now I should be sailing.

I Print them out also. If it happens to one of us it will eventually happen again. If you call Merlin tell him Gary told you to call him. He is a really nice guy always willing to help.
