What is Transistor Controlled Ignition?
Instead of using a distributor to determine when each cylinder fires, the car's ECU uses camshaft and crankshaft position sensors, along with MAP/MAF and throttle position sensors to determine the optimum time to fire each cylinder for the most power/lowest emissions. As opposed to fixed advance (vacuum or centrifugal) employed in distributors. Transistor Controlled Ignition is commonly referred to as Coil On Plug (COP), Transistor Controlled Ignition is just marketing bumpf to make it sound awesome.

Thanks for the feedback!
If you have a 350 with HEI (electronic ignition), it will be under the distributor cap, under the rotor, bolted with two small bolts to the landing of the distributor. … Hope that helps.
Constant voltage delivery Eliminate the need for periodic replacement of points and condensor
A FET is just a material either N or P whereby a restriction is applied by a field volts impressed on the material as restricting the current flow or allow the current f…low
Depending on how the transistor is biased and various other circuits connected to it, a transistor acts as an amplifier and/or switch. When acting as an amplifier th…e circuit containing the transistor can do things like transmit or receive radio signals, perform analog mathematical calculations, generate waveforms, etc. When acting as a switch the circuit containing the transistor can do things like turn on/off a light, turn on/off a motor, perform digital logic or mathematical operations, fetch and decode computer instructions, etc. Exactly what a transistor can do is really only limited by the system requirements and the designer's imagination as to how to meet those requirements. There are several different types of transistors: bipolar junction transistors (BJTs), field effect transistors (FETs), unijunction transistors (UJTs), programmable unijunction transistors (PUJTs), spacitors, surface barrier transistors (SBTs), tetrode transistors (TTs), point contact transistors (PCTs), etc.
I don't think there is a way to check this electrical component other than trying another one. A cheaper alternative is to get a used one at a junkyard and try that first.
for a BJT to amplify we give input signal if suppose we use BJT in CE configuration input is given at Emitter-Base junction and output is taken at Collector base junctio…n the input voltage increases or decreases the forward bias of the E-B junction affecting a change in the base current and we know that collector current is a function of base current collector current also varies so by selectively changing the base current we can effectively change the collector current
Answer the ignition control module is operated by the pcm,the pcm tells the ignition control module when to energize the coils to enable spark
It is basically an electronic "thing" that has three terminals. Lets say E (emitter), B (base) and C (collector). Lets say we connect C to positive of a battery and E to negat…ive (or ground). As long as we keep some current at B , we'll have current flowing from C to E . Basically its some device that controls current on one side from current on another side. the former being larger in magnitude than the later. ANSWER: Is a semiconductor voltage amplifier
Answer It is secured with screws at the fenderwell.
Answer It takes the place of the 'points' that used to be in the distributor, collapsing the coil's field at a precise time, dissipating voltage from the coil to… the spark plugs and firing the air fuel mixture in the engine's cmbustion chambers.
Because the operation of the transistor is determined by the current at the base. the principle equations of BJT operation are: Ic = h*Ib ,and Ie=Ib+Ic thus device operat…ion is controlled by the input current.
Typical of most newer engines, the coil either is used to fire two plugs simutaneously, or each plug will have it's own coil. We will try the first. A four cylinder engine ha…s a typical firing order of 1342. If you split the running mates you end up with 14,& 32. The engine will have two coils, each with two high tension wires coming out and going to the repective plugs. So, that means one coil pack will operate cylinders 1&4, while the other will go to 3&2. The other method with the plugs having it's own coil, the primary wires should be in a loom together at different lengths, and it would be hard to get them confused. I solved the problem by looking how the leads are connected on a Peugeot 205. This has the same transistorised distributor. The firing order is 1 3 4 2 Where Plug 1 is on the RHS looking into the engine from the front and Plug 4 is on the LHS. Plug 1 connects to the Top LH Connector on the distributor (again looking from the front) Plug 2 connects to the Bottom LHS connector. Plug 3 connects to the bottom RH connector and Plug 4 connects to the top RH connector.
The 1994 Ford Aerostar ignition control module is located on thefirewall in the engine compartment. The ignition control modulewill be on the drivers side of the firewall.
I have a 1975 450Sl and the ICU is located on the driver's side, in the front wheel well on the fender just below the coil. It's a cast aluminum looking box. Otherwise, …running from your distributor is a covered wire that holds two internal wires (I think two)... trace that back as it will lead you to your ICU. Tim
base Umm.... Device current results from forward biasing of the emitter-base junction. Thus you can: 1. hold the emitter constant and apply control to the base (most comm…on), or 2. hold the base constant and apply control to the emitter (common/grounded base circuit, mostly used at high/very high frequencies).
