Hi,
Well, I got off easy with my burned wiring. I began cutting open the wire harness from the ECU and as luck would have it, only the one length of wire that runs from the ECU to batt neg was burnt...about an 18" length. So, I replaced the multi wire ring termiinal at batt neg, ran a fresh wire to the ECU ground with a new ring terminal and tied the timing sensor ground shield into it too.
Marty, I think you suggested a piece of inner tube to aid in shielding the corner of the ECU closest to the batt + terminal, I did that too. I didn't realize something you said earlier until I began writing this just now. After I repaired the wiring, put the battery back in, I noticed the spanner laying next the the tool pouch so, I shoved it underneath the tool pouch rubber band to better secure it. You mentioned the possibilty of the spanner bouncing around and contacting the batt+ and shorting against the ECU or other ground in that neighborhood. In retrospect, that might be what happened....damned spanner!
Docc, I rechecked all the grounds and added a ground to the VR housing to the timing chest.
Thank you for your help & insight. Stay well!
