AboutErnest (Ernie) Kenward Expertise The challenges I most enjoy are thoughtful technical questions of a trouble-shooting nature in both electrical, power electronic and mechanical systems, mainly automotive but also machine control and small-machine PLC applications.
Please note, however, that I am NOT a walking shop manual for every car in existence! While I have been described by colleagues and students as having an encyclopedic knowledge of automotive and transportation equipment in general, I do NOT have a collection of shop manuals and detailed specifications for every vehicle in existence! What I DO have is a good collection of literature and hands-on experience with 1950s to 1980's Ford products (plus a developing database of information and practice with the Mercedes diesel cars), along with an engineering perspective and the ability to design and implement custom control, electrical and mechanical subsystems for vehicles. For that reason, I am happy to make my thoughts and efforts available to those who are similarly making a point of learning about their vehicles. In regard to manuals and specifications, your automotive parts shop, automotive parts houses and, often, the public library are good resources for these.
I also have a good track record for trouble-shooting and solving emissions problems in older carbureted vehicles. Doing the latter requires that one has the interest and makes the effort to learn how combustion systems are intended to work and can appreciate how the various systems and settings interrelate - there are no short cuts nor "quick fixes" here; this is a job definitely doing properly and with one's eyes open, as the payoff is not only an honest pass of an emissions test, but an engine which will perform with its intended power, economy and reliability!
Experience One of my key skills both in my work and in my hobby pursuits is STRATEGIC TROUBLESHOOTING. In addition to having been the Power and Driveline resource on the Edsel Owners' Club "E-Team" for the past several years, I am a senior instructor in the School of Electrical & Computer Engineering at the British Columbia Institute of Technology. My main area is Electrical Power and Industrial Control (including PLC applications and programming), and I round this out with course development and teaching of courses in electrical and electronics design and manufacturing, and in AutoCAD and electrically related CAD/CAE software.
From the hobby perspective, I do automotive restoration of all aspects of automotive systems (1959 Edsel Corsair since 1972 and 1978 Ford E250 van since 1985), class-B motorhome conversion (my reason for reworking an E250) and electrical and mechanical custom upgrades as viable ideas and opportunities present themselves. I have designed and produced custom circuit boards to bring back or add features to vehicles when no new parts were obtainable or where a better specification or operation could be had using a more modern circuit. I designed, installed and continue to revise a custom electrical system for my E250 motorhome conversion and, since 2002, this has been managed by an onboard industrial PLC (programmable controller) which has made many revisions since as easy as plugging in my ThinkPad and uploading new firmware.
I am also remanufacturing a sixties-vintage travel trailer, and am using a Moeller 620 mini-PLC in that application as a battery manager.
Also keen on vintage cameras, telecommunications equipment, railway passenger equipment and locomotive technology, fusion cuisine and renaissance music and chorale activities.
Current project - and the one which drew me to this website - is my "new" but very nice Mercedes 300CD, one which developed a minor vacuum problem ... I do not have a shop manual for it yet, so thought I would pose a question ... thanks!

Question Help!!!! We just had an awful trip home through the mountains on 2 very hot days. We have a 1996 Triple E E350 motorhome that we recently bought and have not had any troubles with until now. If we had to go up a steep incline or even a long steady incline, once we got to the top and starting going down the other side the engine would sputter and quit. We would have to coast and pull over and sit for about a half and hour and then it would start and off we go again. The common view of those we have talked to feel it was vaporlocking. We have changed the fuel filter. It ran fine after we were out of the mountain range. What can we do to prevent this in the future?
Answer I shall keep this short, but only because I have answered this type of question - and in considerable detail - a number of times before. If you check out some of my previous answers on this topic, you will find that I generally describe a rerouted replacement of that portion of the fuel line portion that runs through the engine compartment as being a tried-and-true fix to this problem. It goes without saying, of course, that any new fuel line must match or exceed the original in terms of use of the correct steel line and or fuel-grade hose and of secure mounting that does allow for the vibration and slight-movement of the engine.
Most OEM fuel-line installations are very close to the warm engine block, setting the stage for fuel vapourisation in the line in hot weather or under severe engine loading. Routing a new fuel line such that it is away from the engine, ideally ahead of it and within the stream of incoming air, has always eliminated this problem in vehicles I have had.
My E250 class-B conversion has been fine for years now, even in summer hot spots of renown such as Hedley BC, where many make an unexpected coffee stop while waiting for their fuel lines to cool down. I expect to go one better in the not-too-distant future ... I am looking to a diesel conversion as my next project for this vehicle, to better its on the road economy ... and just because it is a neat next project! Aside from the efficiency with which its engines utilise it, diesel fuel offer the benefit of having very low volatility and not much subject to vapourisation in its lines.
Yours is an easy problem to solve. Carry on and may your next summer in the mountains be a non-stop pleasure!
Guess that wasn't quite so short ... oh well ... EGK
