Ignition System Trouble Shooting.

Last time we discussed how magnetic fields cause current to flow in wires. The current flow is then harnessed to make the spark plugs work.

Now we will discuss how to trouble shoot this system.

First of all the system consists of:

-A flywheel with a magnet

-A magneto with a main coil and a switching coil

-An On/Off wire

-A spark plug and spark plug wire.

That’s it.

{In the olden days you had a switching circuit called points, but I will not bore you with that. I have several old motors that have points. (If you are really interested in points I will write an article about trouble shooting those…but not today.)}

So what’s the problem?

The problem is that I was riding my go kart… blew the chain… made a massive clunk…engine still ran right up until I shut it off. I replaced the chain and now it won’t start.

What do I do? Cry? Uh…No…

First off all look at the system. So the engine not running must be symptomatic of

-No Gas

-Flooded (too much gas)

-No compression

-No Spark

-Switch is off!

So yes, I checked.. there is gas. (check!)

The engine has nice resistance and compression (no thrown rods, no loose valves, everything is tight…) (check)

Yes I checked it was ON! Also I removed the off wire from the switch near the engine. Still nothing. (check)

Pulled the spark plug out and tested for spark:

No Spark:

The possible causes for no spark are:

Faulty Spark Plug (ie short circuiting because of ash contaiminents, broken insulator, too much gas on plug)

Or a faulty ignition mechanism

Well I cleaned the plug well. Used a different plug…

Note: But you know what I should have done first? I should have taken the plug wire and tried it against the engine. Well I tried that too: no spark.

Not looking good here… What do we do next?

This is where stuff starts coming apart.

Understand that the system involves the flywheel, so we need to access it and see if the flywheel is okay.

By “okay” I mean the following:

-Is there a magnet in it anymore?

-Did it get damaged? (very unlikely) Check with screwdriver: does it stick? (check, yes there is a magnet)

The next critical thing is to check the keyway. 8 times out of 10 the key gets sheared. This can occur from sudden stops of the engine. A sudden stop can occur from various reasons such as a broken chain grabbing hold of an activated clutch. An instantaneous shock load can be introduced into the system.

The other way an engine can be come jammed suddenly is if the rod blew inside, or the engine ran out of oil (seized up).

Next time…. What happened to the ignition system?

Part of the reality of becoming a new mum is taking stock of your family’s finances and working out how you will cope financially. When you’re considering returning to work, how you will afford to pay for childcare and what kind of childcare you will choose are important decisions. Many new parents will not be familiar with childcare vouchers, how they work and how they can be used to pay for childcare. 

The childcare voucher scheme is a national scheme offered to parents and guardians through the government and participating employers to help with the cost of childcare.

Childcare vouchers are a financially beneficial way to pay for childcare in the UK, because you don’t pay tax or National Insurance on childcare vouchers to the value of £55 a week. This means that working parents can save as much as £1,195* a year by paying for childcare with vouchers. The savings could be double, if both parents sign up for a childcare voucher scheme.

The website Money for Mums has put together a good check list of information on childcare vouchers [1]:

1        Check whether your employer’s childcare vouchers are a benefit that is paid on top of your normal pay or whether it’s part of a salary sacrifice scheme

2        Work out how your tax credits will be affected

3        If your cash pay is affected, ask if your other earnings-related payments will be affected (pension, overtime rates, pay rises etc.)

4        If your cash pay is affected, ask will your benefits-related payments be affected? (will your NI contributions to your State Pension be affected etc.)

5        If your cash pay is affected, ask would any student loan repayments be affected?

Childcare vouchers are redeemable to pay for childcare and child minding ensuring that a parent’s return to work need not have a negative impact on their family finances.

Parents can also be assured when selecting a childcare provider that they have undergone rigorous vetting procedures. Before childcare vouchers can be used to pay providers the provider must be registered with an approved regulatory body and will need to meet the standards set out by that body. Ensuring only registered providers can accept vouchers for payment offers additional peace of mind to mums knowing that their child is being looked after in a safe friendly environment.

Have you been using the same older television for a number of years? Perhaps you are somewhat satisfied with the performance of your current television set, but you can not help but notice all the new high tech televisions with impressive pictures on the market today. There are so many televisions available now which have superior picture quality, as well as being high definition ready, that it is a smart choice to buy a new television set at this time. Since prices are now lower than ever before, and with the digital age now upon us, a new television set is simply a smart investment.

Is This The Time To Buy A New Television?

At this time, prices on new televisions in the UK are at an all time low. Thanks to the increased competition of so many companies producing the newest generation of televisions, the consumer benefits with low prices. In addition to the excellent choice and low prices today, there is another important reason to consider buying your new television now: the dawn of high definition. The older analogue signals, which provide picture to the older generation of tv’s, are being phased out completely. By the year 2012, all television signals in the UK will be digital only, and unless your television is a newer one which can receive the digital signal, you will be unable to watch tv broadcasts at all unless you either replace your TV or buy a set top box.

What Differences Will I Find With My New TV?

The first, and most obvious, difference you will find is in the vastly improved picture quality. The difference between the display of older televisions and that of newer ones is simply amazing. With the newer LCD and Plasma tv’s, the picture is far more sharp, and more lifelike than anything that was possible with the older analogue televisions. You will also find that the new televisions have superior sound quality, and are even are able to connect to home theatres and gaming consoles, bringing sound quality to the level of a movie theatre experience.

Which To Choose: Plasma Or LCD?

Most televisions available today will be either plasma or LCD. Each has it’s benefits, and which you choose depends primarily upon the size you are seeking. LCD tv’s come in a far wider range of sizes: from about 14 inches up to 50 inches and more. With plasma televisions, sizes available are limited to the very large sizes, beginning at about 37 inches. Both of these televisions do process digital pictures, so you will be prepared to watch all your favourite programmes in high definition on either. There is another option for those who wish to receive both analogue and digital signals on their television, the IDTV. This tv can display both sorts of signals, however it does tend to cost quite a bit more than the other two types.

This is the best time to purchase a new television for anyone who has been thinking of it. With prices in the UK at so reasonably low, and the advantages that the new generation of televisions can offer, there is no reason to wait.
