SymTech Labs' customers most frequently encounter coaxial cable, used as “shielded cable,” in SymTech Labs' Premium Megasquirt Wiring Harnesses. The coaxial cable in Premium Megasquirt Harnesses delivers the signal from the crankshaft angle sensor to the Megasquirt ECU while shielding it from electromagnetic interference. It is important to prope… text/html 2009-10-17T03:28:41+00:00 https://www.kb.symtechlabs.com/misc:relay_fundamentals?rev=1255750121&do=diff Relays are electromechanical components ubiquitous in most all automotive electrical systems. A basic understanding of their operation is necessary for nearly all automotive wiring projects. Nomenclature A relay has two parts, a coil and an armature. In the schematic of the relay below, the coil, which has two connections, is on the left side of the relay. The armature, which has three connections, is on the right side of the relay. text/html 2009-11-09T06:01:20+00:00 https://www.kb.symtechlabs.com/misc:soldering?rev=1257746480&do=diff Soldering wires together is a requisite skill for practically every electronics project. Properly soldered joints are mechanically strong, electronically solid and extremely durable. Improperly soldered joints can cause an array of problems, from increased electrical noise to decreased signal to no signal at all. text/html 2009-10-20T04:40:40+00:00 https://www.kb.symtechlabs.com/misc:start?rev=1256013640&do=diff Articles * Relay Fundamentals * How to Solder Wires Together * How to Use Coaxial Cable
