The 4 simple car voltage current regulator circuits I have explained below is created as a immediate alternative to any standard regulator and, although developed principally for a dynamo it will function equally effectively with an alternator. If the functioning of a traditional car alternator voltage regulator is analyzed, we find it amazing that these […]

3-Pin Solid-State Car Turn Indicator Flasher Circuit – Transistorized
Although, most of the car electronics have evolved into solid-sate versions, a turn indicator flasher unit is one device which still depend on a relay based design in many of the modern cars. Disadvantages of Relay Based Flasher There are a couple major disadvantages of a relay based electromechanical flasher unit: 1) First, these being […]
Automobile Engine RPM Servicing Meter Circuit (Analogue Tachometer Circuits)
These useful lightweight, cheap, analogue tachometer circuits are developed for facilitating car or auto servicing mechanics for precisely adjusting a car ignition system RPM to get maximum efficiency from it. The proposed circuits are actually combined results of a tachometer and a dwell meter. Application The car RPM servicing meter circuit can be applied for […]
Converting Wasted Spark Ignition to Sequential Spark, for High Efficiency Combustion
In this post I have explained a simple method of converting a wasted spark type ignition system in an automobile, into an enhanced, sequential spark, 6 cylinder engine type ignition system. The idea was requested by Mr. Brenton, as given below: Main Requirements I was looking through the car and motorcycle section but couldn’t find […]
Automobile Tester Probe Circuit [Car Fault Finder Probe Circuit]
This simple automotive electrical fault finder probe circuit will enable you to solve most electrical troubleshooting in your cars, tempos, motorcycles etc with a lot of ease and in a hassle free manner. The idea is very simple. The circuit exploits the high impedance gate value of the MOSFET which makes the circuit extremely sensitive […]
