Lost spark

I'm puting a 408 stroker in my belvedere..motor was running good until my zbar smacked my positive battery cable while car was off..noticed negative battery cable melting..since then I have no spark..the car has electronic ignition I tried a new coil and ignition box still no spark..did I fry something out? Thanks

take off the yellow "ign" wire off of the starter relay to disable the starter. turn ign sw to "on" & check for voltage at the ballast/coil positive primary/"point" of the ECU pentastar connector (assuming 4 pin ECU/2 terminal ballast). Have a helper hold the key to "start" & recheck the above.

Yes it is a 4 prong plug.. I'm getting power to where needed..still not getting spark from coil thanks for your help

take off the wire from the coil negative primary terminal & w a jumper wire w alligator clips on each end ground the negative primary terminal (not the wire you removed from the terminal) to ground repeatedly like Morse Code and w the coil secondary wire (the dist end) held 1/4" from ground see if it will spark as you make/break contact (ign on) w your jumper wire. This tells you the coil/ballast/ign sw and their attending wiring is OK and leaves the ECU and the dist pickup (& their attending wiring) as the culprit. The above could perform OK when cool and act up when hot but you should see something. Holler back.

Have U checked the fusible link @ the bulkhead connector?

I am not exactly sure what you mean by coil secondary wire. A side note i tried a different dist. Three ignition boxes and 3 coils 3 ballast resistors some old some brand new.

The wire from the coil center terminal to the dist center terminal.
