ignition coil
Decided to replace my condenser and ignition coil so I pick up the msd blaster 2. Once after looking at the diagram I see that there is only one wire going to the + part of the coil but on my car there are 2. If still using the point distributor msd says you need a .8 resister on the + wire but I have no clue witch one to put it on should I put it on both. After some reading I find out that some cars have wires also have a second wire from the starter so that on startup it gets a full 12 V

liquidpower,
One of the wires comes from the starter to the coil to provide higher voltage when starting. The other wire is a calibrated resistance wire supplying power from the ignition switch to the coil when the car is running. This wire should be very flexable and identifiable from the wire from the starter and is usually black in color. Hook the new coil up just like the old coil is hooked up and you will be fine. Good luck

so don't even worry about putting on the resistor on the black wire msd said i should but ill give it a shot and if it runs crappy then ill just put the resistor on the black one
thanks a million guys
love this site

thanks
appreciate it just wonder what the consequences cloud be if i didn't have one all ready and didn't put one on maybe the points arcing. or the coil melting and my car bursting in the flames

citcapp is right. if it is still the factory wiring then you wont need the resistor. the way to check this is with a volt meter. turn the key switch to run and see what the voltage is. if it is 12 volts then you will need the resistor. if it is (i can't remember for sure) i think 6 or 7 volts then you will not need it.

In your application, the MSD coil is no different than the OEM unit you are replacing. Some might think it is prettier, but that's it.
Just put the wires on the same terminals.
