What I’m looking for is practical, technician-level guidance that will let me pin-point the root cause of each fault quickly and get the cars back in service with minimum downtime. Clear diagnostic steps, wiring-diagram interpretations, recommended test points with a multimeter or oscilloscope, and advice on safe component swaps are all valuable.

I want to build a turnkey GPRS-based tracking solution for a small fleet of up to ten vehicles. The platform must stream each vehicle’s live GPS position, keep a searchable log of every route taken, raise instant geofencing alerts, and give me remote engine-cut capability together with reliable petrol-level monitoring. Hardware • A compact on-board unit that pairs a high-sensitivity GPS receiver with a quad-band GSM/GPRS modem. • Wired inputs for ignition status, fuel-level sensor and an output relay for safe engine cut-off. • Over-the-air firmware update support so I never have to recall a device for basic fixes or tweaks.
