Electronics with diesels!!!!!!!

Hi Axle,

I agree to a point. Electronics are normally reliable these days however if something does go wrong, as they say, you are up the creek without a paddle. You cannot fix the dam thing yourself!

G'day Axle
Yeah. most stuff is reliable, far more reliable than most previous gear But issues can still happen.
If the governor is external on the pump but is working in a very hot environment, then that could be the problem and not the inherent reliability.

From some past experience with failed items, namely full electronic distributors, a friend and I made a vacuum cleaner hose run from cooler site and with a computer fan fed cool air onto the electronics. After that no failures despite the vehicle being used in far hotter situation and working harder.
So, if heat related, cooling the gear may work and prevent the heat being an issue.

If your item uses HALL EFFECT sensors to detect revs then they often suffer heat failure.
The governor may be ok just Hall sensor stuffed. An electronics whiz may be able to fix it for you, as long as they know what it is supposed to do as they may not be mechanically minded to see the application.

As they say electronics are 1000 times more reliable then their mechanical cousins. When the mechanical cousins fail, they often fail gracefully, whereas electronics failures can be catastrophic.
I hope it works out for you.

Troll of the week huh Axle?

Why just diesels? Petrols have the same amount of electronics.

People forget how unreliable old cars were. Living in lala land.

Hello Axle,
sorry to hear your digger is out of action.

Greatest problem is the price of components and availability rather than them breaking.
A set of electronic injectors for a small engine around 4 to 6K fitted where the old injectors in my case I replaced for $500 and that was 8 top of the line units.

Electronics are very reliable on the whole even when subjected to heat and humidity.

Underground units operate in high heat and high humidity with rock temps at times around 50 degrees and humidity to 100%. Some will say you can't have high temps and high humidity but u/g can.

The greatest problems experienced by the auto sparkies are mechanical damage and fitters that probe the wiring with those spike test lamps. The wiring is the greatest problem. Water in plugs and green death.

Hope it is fixed soon,
RA.

People can't function in these circumstances.

Modern electronic devices have become very reliable, however a minor problem in an Engine Management System can render a vehicle immobile.
By far the most common fault in electrics or electronics is water or humidity contamination either within the device or in the associated connectors. This either produces electrical leakage or corrosion.

Some automotive connectors are designed to be "waterproof" but this is usually only reliable for the first few years until the seal deforms. A good strategy is to seal all connectors in the looms and on the devices with self-amalgamating tape or similar. For oddly shaped situations where tape is difficult to apply, a putty-like material such as Coax Seal (Jaycar) can be moulded around the component. These materials can be easily removed if need be. Cured silicon will also do a good job but is difficult to remove if access is required.

Connections in the engine bay and under the vehicle are at most risk particularly if you ford creeks or do any beach driving but even humidity can eventually cause corrosion problems with electrical contacts and connections. Changes in temperature and air pressure cause moisture-laden air to be "pumped" in and out of the enclosures leaving behind moisture to feed corrosion.

So..... Slip, Slop, Slap the waterproofing!

Even a stone age dinosaur like me would have to agree that todays electronic engine/transmission management systems are pretty reliable. For me the older mechanical system was a little easier to diagnose and sometimes a "bush fix" could get you mobile again. Try arguing with an ECM that doesn't want to play anymore (:-(( Even tried wacking one with a screw driver, still wouldn't cooperate..(insert suitable expletives)

I guess their is not much you can do about the excavator Axle - but with our cars there is.

The cost of fuel pumps , injectors etc was about 5 or 6 to 1 when I considered the 200 series diesel against the petrol Patrol I bought.

The low cost means I carry some of these vital components now.

Worth considering if one strays far from the main roads.
