ELECTRICAL SYSTEM – Battery terminals

Posted by:

ELECTRICAL SYSTEM – Battery terminals
 PURPOSE
The purpose of the battery terminal is to hold all the cables either on the negative or positive battery poles. The battery terminal needs to be in fixed position. A sure connection is a connection that will not move. The best battery terminal is a brass battery terminal as it is not workable or malleable. There are many different types of battery terminals on the market. Most of these terminals do require replacing over ...

Weekly Checks – Battery Level

Posted by:

ELECTRICAL SYSTEM  – Charging system – Battery
PURPOSE

The purpose of the battery is to receive the charge from the alternator. This charge should be received in a perimeter of 13.8-14.2 volts. If this charge is lower, eg 13 volts, the battery will be affected. If the charge is higher than 14.2 volts the battery will also be overcharged and this will shorten the life of the battery. The battery should be checked to make sure that it is receiving at ...

Charging – Alternator

 

PURPOSE

The alternator is a component that is fitted outside or around the front of the engine.  It is a round component and has a fan belt connected to it.  If the fan belt is connected tightly it will allow the alternator to charge somewhere between 13.8-14.2 volts.  The alternator is designed to charge at this voltage to the battery.  The alternator’s purpose is to keep the battery recharged..The alternator is not designed to fully charge the battery ...

Cooling System – Heater Core

Posted by:

Cooling System – Heater Core
 PURPOSE
The heater core is designed to dissipate heat providing driver and passenger comfort. Heater cores should last at least 5 years before they start to give trouble. They are like a smaller version of a radiator except it dissipates heat for driver and passenger comfort whereas the radiator dissipates heat for a normal operating temperature for the engine in all speeds and conditions. A heater core is usually made up of a copper core ...

The Noise – Ring gear slipping

Posted by:

Noise – Ring gear slipping
 THE EFFECT
The whole neighborhood gets to hear it! It’s a high pitched metallic noise that when cranking the pinion gear from the starter motor is trying to turn the ring gear that has no teeth left.

THINGS TO LOOK FOR

Basically what you will find is that with every second crank, every fifth, fifteenth or hundredth crank, you will hear this noise.. If the noises become more common, eg. every second or third or tenth crank, ...

The Noise – Loose Timing Belt

Posted by:

Noise – Loose Timing Belt 

 THE EFFECT
A loose timing belt will rub up against the plastic housing surrounding the belt. It also can cause a distributor drive to chatter at idle. A loose fan belt may slip causing the timing to go out which can give poor performance or cause a potential misfire.

THINGS TO LOOK FOR

If you feel you have a suspect timing belt you may have to remove some of the housing to get to it to feel the ...

ROAD TEST – Checking for warning lamps

Posted by:

ROAD TEST – Checking for warning lamps
 PURPOSE
Warning lamps are designed to let the driver know of possible major problems before they occur. The main lights are brake, oil, charge and temperature as well as seat belt lights. Gauges will warn if a problem is starting or getting worse. All warning lights are designed to turn on with the ignition and off when the engine starts. Most gauges are designed to start with the reference points and gradually move ...

Weekly Checks – Oil Leaks

Posted by:

Engine – Oil Leaks – Rear Main Seal
 PURPOSE
The rear main seal is at the rear of the crankshaft, sealing the oil inside the engine and preventing it from leaking outside the rear of the crankshaft. The rear main seal is designed to last at least 100,000kms. Unfortunately, with a longitudinal motor, rear main seals may only last 60,000-80,000kms.

THINGS TO LOOK FOR

When checking for oil leaks it’s always good to check underneath the vehicle around the rear of the ...

ELECTRICAL SYSTEM

Charging system – Alternator to the battery lead

 

PURPOSE

The purpose of the lead from the alternator to the battery is to supply the power from the alternator to the battery.  This charging power is good for at least 5 to 10 years.  After this time the cable may become hardened or the connections may be creating a resistance.  All this means is a power voltage drop between the alternator and the positive battery terminal.

 

THINGS TO LOOK FOR

The best way ...

ELECTRONIC FUEL INJECTION [EFI] Relay

Posted by:

ELECTRONIC FUEL INJECTION [EFI]

Relay

PURPOSE

The EFI relay is a heavy duty electronic switch that requires very little voltage to switch on at the same time  It may connect a moderate amperage circuit without the switch wearing out.  It is also designed to disconnect if overloaded.

 

THINGS TO LOOK FOR

The EFI relay is an important switch that rarely goes wrong as most relays are reliable for approximately 10 years.  After this time they may start to develop intermittent problems, eg cutting out.  Also ...
