Eberspacher problem

[alanducker]

I have a D3L unit which has failed to start after not being used since last season.

When the control switch is turned to cold operation the fan works continuously.

When turned to full or half heat modes the fan worked for about ten seconds then stopped. The burner did not get to the stage of firing.

To make matters worse after checking fuses and connections and finding it still did not work, I accidentally left the switch turned to full heat mode for several hours. Now the fan does not even work for the ten seconds. It does still work on cold mode however.

The battery voltage (at the batteries) is OK but just in case I tried starting the heater with the engine running at about 2 000 rpm, but again the heater would not work.

Although I think the problem is electrical I did check the clear plastic fuel line to make sure there are no air locks.

Can anyone offer advice on what could be wrong and what to do.

Alternatively can anyone recommend an engineer who understands these things in the Poole area.

I have the same unit and similar problem starting up. For me it was down to insufficient battery power. It appears they need quite a bit to fire up.

Have you checked that the little in line fuel pump is clicking away to lift the diesel? Next thing is to check the glow plug. I understand that this should feel warm under its rubber cover ( if u can reach it mine is almost impossible) or if u can get to it easily remove and check.

Make sure all the conections are sound I went around mine with an AVO meter and found the main power had been pulled at one place whilst Id been fixing something else.

Finally company called Kreuger in ChandlersFord (Nr Southampton) are the service people.. havnt got the nr to hand . They were very helpful but I suspect may be a bit pricey for a call out.

Good luck Nick

Can you get access to the glow plug ? It might be short circuited due to a build up of carbon. You can clean it with a wire brush. Krueger Marine are your nearest dealer and they installed my new unit 2 months ago . Details are as follows:
Krueger (New Milton) Ltd

Don't hit me for saying it but............. are you sure that there is sufficient diesel in your tank.
I am more tecnically minded than most and felt a right **** when I couldn't get mine to fire on heat setting. The pump would click away for a bit then the unit would shut down. After a while it shuts down for a long while.
Problem was the pick up pipe is quite short so as not to starve the engine and had run out of fuel.
Just check - I hope its that simple.

Thanks for your and all the other comments.

The diesel tank is full but the fuel pump is not clicking, which again makes me think the problem is electrical. The clear section of the fuel pipe was also full of fuel.

Voltage at the batteries is good but I have not tested it at the heater unit. (Does anyone know which wires to check?)

I don't recall the glow plug under the rubber cover feeling warm but this is something to check again at the weekend. (Would it be cold if the plug needed cleaning?)

If all else fails I will try Clive at G & C. Eberspacher say Kreuger are their main agents for the south coast but travelling from Chandlers Ford will run up the costs before they start looking at the unit.

Had a similar problem, and was caused by the fuel supply line becoming disconnected from the heater unit end. It ran for a bit, realised there was no fuel and then gave up. If, as you say, your fuel pump is not clicking, this seems to be the first thing to check as if no fuel is reaching the heating unit then it will cut out.

On my old DL1 , there was a push button cut off for the fuel line. Once it was pushed back in , the pump could then supply fuel. It was a long time ago but I think the switch was under a rubber cover on the top of the unit. You simply feel for the rubber cover and push it down. Might be worth looking at.

Easy my friend...

You have to have it servised !!! The blessed control unit is programmed to prevent it from trying to start if it misses three start attempts....

I know because that is exactly what mine did last year.

My best suggestion is to take it out yourself and have it serviced by the main agents. Then put it back yourself. The service ony from South East Auto's at Maidstone is about £130. Your local agent should be about the same price. The agents will charge you mileage to come out to the boat and back twice if you have them do the taking out and putting back!!

The wiring should all come appart with Male Female plugs so that you can't put it back together wrong. The power to the fuel pump on mine did not have a plug so I cut the wires and inserted M F bullet connectors.

Next year you can take it out early and clean up the glow plug and other bits yourself before it becomes unreliable. There is a filter gause in the combustion chamber and a couple of gasgits that need replacing.

Good luck

Oh join the club !!!

Don't worry about leaving it on the electronics turn it off after a false start.

The most obvious is low battery voltage but if your charge circuits are all OK then the engines running should solve that one which you have tried.

Next step is to go to the unit, there is a temperature sensing cut out which looks like a push button push it in, if it clicks loud click then the cut out prevented the unit from starting.

Switch on in the normal way

If this fails then get a voltage meter and connect it across the battery tags of the glow plug NOT the high voltage sparking bit that looks like a spark plug from a car.

There are 2 tags lugar types connect up the meter and measure the volts get a friend to switch on the system if the system is 24volts you should get a reading of about 9 to 12 volts and a clicking of the diesel pump as it goes through the start sequence.

If you get a reading of 24 to 28 volts your glow plug is duff

You can buy these for about STG 40 from Kruger in the new forest somewhere. THey are also the main dealers and will come out to the boat and sort it for you but standby for a STG 200 bill

Last point if she does fire up it will smoke like hell and stink for an hour but you will be so pleased with yourself it won't matter....right ??

Good luck

David
