Automotive Electrical Circuit Manufacturer,Supplier and Exporter in India

Product Code : EL-AELE-9368
Jlab Export is a leading Automotive Electrical Circuit Manufacturer,and suppliers in India

A vehicle starter, horn and lamps all draw on one battery through fuses, switches and relays. This trainer sets those circuits out on one circuit board module, laid out like a typical vehicle system, with a solenoid, relay, DC motor, switches and lights. Students work from the battery and fuse through the starter, horn and lamps to basic fault finding.

Practicals on Starting, Horn and Lights

Practical work starts at the battery. Students read its open-circuit voltage with a Digital Multimeter, check it under load with a Battery Load Tester and test each fuse for continuity. In the starter exercise they see a small switch current pull in the solenoid, which then closes the heavy circuit to the motor. A voltage drop test across each cable and the earth path finds a poor joint that a plain continuity test can miss.

For fault finding, students work outward from the fuse: supply at the switch, output from the switch, voltage at the lamp or horn, then the earth. Students can then repeat the checks on the Mock Layout of Car Wiring Conventional Type. It adds a self starter, alternator, ammeter and ignition system.

Frequently Asked Questions

Why does a fuse keep blowing?
A fuse that blows again at once usually points to a short circuit to earth, such as a chafed wire touching the body. If it blows only after a while, the circuit may be drawing too much current through a faulty part. Never fit a larger fuse. Find the fault by isolating the loads one at a time.

How does it differ from the lighting circuit trainer?
The Automotive Lighting Circuit trainer deals with lighting alone, including interior and vanity lights. This board adds the battery and fuse, the starter with its solenoid, the horn and fault-finding practice, and carries a DC motor.

Why does the starter circuit use a solenoid?
A starter motor draws far more current than an ignition switch can carry. The switch only energises the solenoid coil, and the solenoid closes heavy contacts between the battery and the motor. On most starters it also pushes the drive pinion into mesh with the flywheel ring gear.

How do you find an open circuit or a bad earth?
With the circuit switched on, measure voltage at each point from the fuse to the load. The reading drops to zero after the break. If full voltage also appears on the earth side of a lamp that will not light, the earth path is open or has high resistance.
