Скачать или смотреть Build a DIY Gauge Voltage Stabilizer For Your Classic Car - CHEAP

This week we are fixing the gauge voltage regulator on our 1964 Triumph TR4 using just a few dollars of electrical components! We will crack open our failed regulator, discuss how it works and why it failed, and then rebuilt the whole thing. Are our gauge voltage issues a thing of the past? Find out on WEGS GARAGE!

Electrical gauges and instruments on older cars require stable, regulated voltage to accurately display information like fuel level and coolant temperature. This voltage is supplied by a voltage regulator, sometimes referred to as a “gauge voltage stabilizer.” Old versions were often a bi-metallic thermal-mechanical device, which was prone to wearing out over time. Today, a simple electrical linear voltage regulator chip can accomplish the same thing at a fraction of the cost and complexity. Replacement gauge voltage regulators are available using this technology. However, converting your existing regulator is inexpensive and fun.

Here are the parts needed for the conversion:

LM7810 Linear Voltage Regulator (or similar IC)
.33 micro-farad ceramic capacitor
.1 micro-farad ceramic capacitor
Failed voltage stabilizer case

This circuit is for 10 Volt gauge voltage. If your car uses a different voltage, purchase an LM78XX chip with the last two numbers corresponding to your voltage. For example, for 5V gauges, purchase an LM7805.
