Engine harness meltdown after rebuild
 

I just finished removing all the Zenith items from the engine harness of my 1970 t now that I have a 2.7 rs w/ pmo's. I removed the electromagnetic control valve, the intermediate unit, the aux start unit, and re solderd the 14 pin plugs. Turning the ingnition to on position (not start) the ground strap from 3 pin cdi to coil bracket and ground strap from cdi to frot cam cover melted it's plastic shield covering. What did I do? Looks like power is shorting from engine coil bracket to groud. Where could the short be?
Any help appreciated.

You mentioned that you resoldered wires in the fourteen pin plug. Did you happen to get any of the wires in plug mixed up?

Good idea. The only two hot wires should be the red coil jot and yellow from starter correct?

Which 14 pin plug did you modify?
there are 2 males and 2 females you can "adjust".

I just finished building an engine harness for someone that completely eliminates the fuse panel and plugs directly into the female main wiring harness using a male plug on their '70, with PMO's, Pertronix and MSD on a 2.7. Completely plug and play.

Feel free to PM me with your phone number and we can go over what you may have done.

Here is the harness I made for him:

Pin out for your car's normal engine harness (to the engine):

pin 1 Yellow to Starter
Pin 2 Green not used
Pin 3 Black or Green/Black to Oil temp sender
Pin 4 Green/Red to Oil Pressure sender
Pin 5 Green/Yellow to back up light switch
Pin 6 Grey/Brown to back up light switch
Pin 7 Red Black to Thermo Time switch for Cold start system
Pin 8 White/Red Or Grey/Red to Micro switch
Pin 9 Purple/Black to Points
Pin 10 Blue/Yellow to positive of ignition coil
Pin 11 Blue to Alternator D+
Pin 12 Brown to Alternator D-
Pin 13 Black to Alternator DF
Pin 14 Red to Alternator B+

So, What did you change?
All you would need to do to remove those devices from the engine harness, is remove pin numbers 7 & 8 and then remove the small gauge yellow wire from pin 1 leaving the large gauge wire in it.

Did you also modify the 2 14 pin connectors on the fuse panel?

Thanks for the break down by pin. I will get back with an update soon.

The pin breakdown is only for the engine harness to rear fuse panel connector. The pin breakdown for the mid point of fuse panel to body harness is different.
