jimmy, my MSD is off to elpaso texas. thanks, tho. it is my second car, so it isnt that big of a deal. thanks alot.. i forgot to sketch which magnetic pickup wire (on car) goes with the purple and which goes with the green. so i may call you if the repair tech changes out my pigtail. opps! :(

MSD Wiring....
 

See if this will help. This is how I wired the MSD unit on my SC. Looking at the master plug from the top with the beveled edges
to the front the wires are:

Bosch CDI Plug = MSD Wires

Front row left to right
1) System Ground = Black coil wire
2) Tachometer Signal = Black wire from left end of MSD unit
3) Signal Ground (green
wire shield) = Purple wire

Back row left to right
4 Coil Hot +12 volts = Orange coil wire
5) Switched +12 volts = small Red wire
6) Signal Pos. (green
wire center conductor) = Green wire

Heavy red wire is +12 volts from the starter terminal
Heavy black wire is ground

Good Luck!

i won!

got the MSD back from the factory. they charged me $25 = $6 for shipping. the car started right up. apparently the note said, i shorted a diode, and fried some capacitor.

thanks guys.

YEEPIE!!!!!!!!!

good ending.

so the welding much earlier may have weakened your box? Do you have a rough idea on how many miles the welding was before the msd failure? I've heard to disconnect both positive and negatives from sensitive elect's. Don't remember the source but I took it seriously? Also I would think a diode would be sensitive to a surge?

thx for info. http://www.pelicanparts.com/support/smileys/wat6.gif

i dont think any miles. the car died at the bodyshop. i cant prove anything. i wish i knew more.

thanks guys.

Cliff,

Great news ... at least you didn't get the 'we can't fix it' routine, and it was only $31!
