About the12volt Contact Us Site Search Resistors Resistors, like diodes and relays , are another of the electrical components that should have a section in the installer's parts bin. They have become a necessity for the mobile electronics installer, whether it be for door locks, timing circuits, remote starts, or just to discharge a stiffening capacitor. Resistors are components that resist the flow of electrical current.
Resistors are color coded.
It's that easy. If a resistor has 5 color bands, write the corresponding number of the 3rd band to the right of the 2nd before you multiply by the corresponding number of the multiplier band. If you only have 4 color bands that include a tolerance band, ignore this column and go straight to the multiplier. The tolerance band is usually gold or silver, but some may have none. Because resistors are not the exact value as indicated by the color bands, manufactures have included a tolorance color band to indicate the accuracy of the resistor.
