The Electrical Practical Training Board System should be designed to realistically simulate the electrical system on an auto mobile. The unit should consist of a number of modular demonstration panels, which should be mounted on a wheeled stand with special powder coated aluminum rails, for Plexiglas panels, which gives secure and firm fitting modules. Also should contain a power source and component connecting cables. The components featured should be real original parts as commonly used in automobile typically produced by the major car or component manufacturers.
The system could be used in the classroom as a demonstration unit to show students various types of wiring and to familiarize them with typical car electrical systems. Also it could be used as a trainer with the student performing actual wiring exercises with the various components.
Specifications:
1. Requirements:
The Original components should be mounted on clear Plexiglas panels that allow high visibility of all parts and wiring.
Panels should be fixed vertically to a frame which should be mounted on a heavy-duty aluminium frame mobile stand.
Vertical presentation of panels should simulate the schematic presentation of common vehicle wiring diagrams.
Panels should feature wiring guides and icons which have been silk-screened onto the panels so as to familiarize the student with schematic type wiring diagrams.
The wires of each component should be brought to 4mm wiring terminals/safety sockets mounted on the panel.
Connection of the components should be easily accomplished by using the cables with stackable 4mm plugs that are provided.
A 12 Volt DC transformer that duplicates the power as supplied by a car should furnishes power to the components.
2. Modules:
DASHBOARD PANEL
The panel should have a central control and switching panel containing an ignition switch, turn signal switch, hazard light switch, brake light button, high/low beam headlight switch, headlight on/off switch, fog light switch, horn switch, reverse lamp button, passing light switch, ampere meter, voltage meter, fuse box and various relays. Panel should have a special central power switch to quickly cut off all power for safety.
INSTRUMENTATION PANEL
The panel works in conjunction with the dashboard panel and provides extra instrumentation as found in many vehicles such as tachometer, speedometer, instrument panel light, high beam light indicator, open door lamp, fuel gauge with sender, charging lamp, water temperature gauge with indicator lamp, oil pressure lamp, left and right turn signal indicator.
REAR LIGHTING PANEL
Should feature two tail light units (with turn signals, brake lights, parking lights and reverse light), a 3rd brake light and license plate light.
FRONT LIGHTING PANEL
Should feature two headlights, two fog lights, two turn signals/parking lights and a horn.
CONVENTIONAL IGNITION PANEL
Should have a conventional breaker-point distributor (4cylinder) which is driven by an electric motor, 12 Volt ignition coil and four functional spark plugs. Note the distributor can be “timed” by using the pulley on the electric motor and timing light. Various engine speeds can be simulated by controlling the speed of the electric motor with the rheostat control provided.
ELECTRONIC IGNITION PANEL
Should feature an electronic ignition distributor (4 cylinder) which is driven by an electric motor, 12 Volt ignition coil, electronic control and four functional spark plugs. Note the distributor can be “timed” by using the pulley on the electric motor and timing light. Various engine speeds can be simulated by controlling the speed of the electric motor with the rheostat control provided.
DIESEL IGNITION PANEL
Should contain two glow plugs, diesel ignition switch, glow plug pre heater indicator.
ACCESSORIES PANEL
Should contain common accessories found in vehicles such as windshield wipers with motor and switch, cigarette lighter, dome light, courtesy light, interior light and door open senders, ventilation blower motor with switch.
RADIO PANEL
Should contain a typical car radio/cd player with speaker, and antenna system.
TRAILER PANEL
Should feature a multi pin standard trailer to vehicle electrical coupling with brake light, parking light, reverse light and turn signal light as would be contained on a trailer.
ALTERNATOR TEST SYSTEM
The system should be a bench top unit designed to operate and demonstrate the alternators below. Unit consists of an electric motor to drive the alternator units, amp meter, volt meter and various other demonstration circuits
ALTERNATOR (A/C)
The unit should be a semi-sectioned original automotive alternator is designed to operate with alternator test system in order to provide an example of A/C generating system for an automobile.
STARTER MOTOR
Should be a semi-sectioned original starter motor that is mounted on a base plate which features electrical connection terminals. The starter is operable and some internal parts are visible during operation.
THEFT ALARM PANEL
The panel should feature a standard theft alarm system (after market type) which is designed to discourage auto break-in and theft.
CENTRAL LOCK PANEL
Should have 2 station central lock system for automobile doors with key type and central controls.
POWER WINDOW PANEL
Should contain one power window mechanism with door mounted and central switch controls. Also features a window lock device which is usually near the drivers position.
