Duncan,
We can process payment at your convenience. Please provide an “invoice” or payment details for 50% of the diagnostic costs, and we will arrange a telegraphic transfer payment for the said amount. Please copy cglyncher@fischerpanda.com with these details.
Based on the photographs only, we believe that the root cause of the “carbon deposits” is bad fuel and/or over loading of the engine. The AGT4000 is designed for intermittent use and if used for a continuous period, it should be operated at about 125 amps maximum.
Thanks and best wishes,
Ashley Rushton

4000
Ashley,
A status. We've invested some time in initial diagnostic work, but our genset still isn't running... When replacing the broken exhaust manifold in preparation to get it running again, we found a severe restriction in the exhaust side of the cylinder head. I sent you some pictures on 6/26/05 showing the exhaust-side restriction (down to about a 1/4" hole through the carbon deposits). Any thoughts on this? I've attached the picture again, just in case you didn't receive the last one.
We decided to remove the head and service it before trying to run the engine (and proceed to diagnose the root cause of the problem). Once we get it running again, we'll check fuel flow, exhaust back-pressure, RPM's/load -- and anything else we can think of to explain the heavy carbon/soot deposits.
We have spent about $620 USD so far on the genset pre-diagnostic work ($890 NZ) -- and we are just now to the point where we can begin the head re-build.
The estimate I just received to get the unit running again -- head cleaned-up, valve job, injector serviced, intake manifold repaired, new exhaust manifold on, parts, labor, etc -- is estimated at an additional $1500 NZ ($1050 USD).
Fischer Panda was willing to cover 50% of the initial work up to $400 US. I think we are nearing that limit. How do you want to contribute to this cause? Will you reimburse me for my costs or pay Pacific Power/Ovlov Marine directly? I have not paid the initial invoice of $890NZ, but will need to soon. Let me know.
Thanks,
Duncan

Subject: RE: Whisper's AGT 4000Duncan,
I apologize for the delayed response.
Your proposal is very comprehensive and appears to have covered all likely options to evaluate the viability and cost of restoring your generator to full operation. We are willing to work with you to assess what is the best option, but are not willing to do this at 100% our cost
We believe that our initial offer to cover 50% of the diagnosis costs is fair under the circumstances.
Please appreciate that:-
1. The cost of diagnosis is not normally covered under warranty,
2. The warranty on your generator engine has expired and
3. Current speculation suggests that the installation may have
contributed to the generator problems.
At this stage I can confirm that Fischer Panda Generators will contribute 50% of the diagnosis cost – up to $400.00
Regards,
Ashley Rushton

Ashley,
Duncan Owen here RE: our Fischer Panda AGT 4000 12V DC genset. I talked to
Colin the other morning and he suggested I contact you directly to sort this
out. I have a proposal that may be palatable to both of us and may help us
get the unit running again. It is an incremental diagnostic plan with each
step indicating what the next step will be. We will leave the unit in the
boat.
If Fischer Panda will pay for an initial 4 to 8 hours of diagnostic work (up
to $300 USD), we will know better what our next step should be. I would
propose the following tasks be performed in the first 4-8 hours:
Day 1 (4-8 hours)
1.) Pull the injector and check (determine need for service, service is
likely required)
2.) Check the compression and deduce valve/ring condition as a result of
this test
3.) Pull off the old corroded exhaust elbow, inspect inside the head
through the exhaust outlet (if possible, to ensure no clogging, rust, or
other obstructions)
4.) Pull off the intake manifold, determine condition of manifold, screws,
and lock-washers -- decide if replacement is required or can be modified and
bracketed to stay tight (with worn-oval mounting holes).
At the end of Day 1, we will have enough information to decide whether to
proceed to day 2. Assuming the compression is good, the valves and rings
appear to be in good condition, and the injector is fine (or once serviced,
will be), we will want to go to the next step.
If there is a problem with the compression and it is determined that the
valves and/or rings are bad (i.e. the engine is shot or nearing failure and
will require a re-build), we will discuss what to do next. One option might
be to remove the genset from the boat for a full diagnostic assessment on
why/how this happened. I would not ask Fischer Panda to pay for a re-build
until we understand what caused the failures, how much the repairs would
cost, and whether it is even worth fixing.
If the engine is still fundamentally sound, I would like to proceed to "fix"
the genset in-place with a minimal 8-16 hours further investment by Fischer
Panda. Before day 2 & 3 commences, service or replace the injector if
necessary (we can discuss who pays for this service/replacement once we get
a report on the condition and a quote for service/replacement).
Day 2 & 3 (8-16 hours)
1.) Replace the exhaust cooler elbow, studs, lock washers, nuts, and gasket
(have the main cooler and other fasteners, will need an appropriate hosebarb
and gasket).
2.) Replace (or if unnecessary, just re-install) the intake manifold,
bolts, lockwasher, and gasket -- add a bracket to reinforce the top of the
manifold.
3.) Replace the crankcase end-plate and gasket (I have this part and a
gasket). Re-attach all wires and brackets to end-plate (return to factory
condition).
4.) Clean, replace, or remove the oil screen (need to tilt the engine to do
this?).
5.) Replace the internal engine mounts (have these) while the engine is
tilted.
6.) Clean up the unit and inside of sound shield as much as possible (from
prior oil and saltwater leaks).
7.) Get the unit running.
8.) Adjust the fuel setting and RPM's to the correct level.
9.) Check the engine output (electrically and mechanically, look for dirty
burning).
10.) Try to determine the root cause of the dirty burning (again).
11.) Try to determine why the generator is only delivering 2/3 its rated
electrical output.
This day 2 & 3 work will cost about $600 USD.
If we can discover the root cause of the dirty burning engine, that would be
great. However, during all the investigative work performed while still in
California, no one could figure out what was causing the dirty burning and
sooty water-filled exhaust. The long exhaust run with less than 2 PSI of
back-pressure (as tested in San Diego by Shea Weston in 2002) were never
enough to explain the sooty exhaust -- and the water separator, though
correctly sized, allowed soot-filled water to pass through. I'm willing to
make compromises to get another 1000 hours out of the unit if possible. The
unit has just over 1130 hours on it today, and it has not been run for three
months (and cannot run because of a corroded-through exhaust elbow). Let's
see what we can learn after the initial day of diagnostics.
I have attached a Word Document that provides an email thread of most
correspondence to-date regarding this AGT unit. Todd Rickard, Dave
Thompson, Shea Weston, Bob Grubert, Sara Jewell, and Mark Yerex have all
been involved with these issues over the last 3+ years. I am CC'ing the
prior participants in this issue as a reminder, so they can discuss this
with you if needed.
If there is a concern that we didn't file appropriate paperwork for the
initial warranty, I believe Dave Thompson may have copies of the paperwork
he filed when he performed our 30 hour service. We have been in contact
with Fischer Panda enough times over the years that if there was a problem
filing our warranty paperwork, we would have discussed it before now.
I'd appreciate your response to my above request via email. I look forward
to hearing from you.
Thank you,
Duncan Owen
