I cleaned all eight ground connections
1 Battery post ground
2 battery ground wire @ firewall
3 Transmission ground @ body
4 transmission ground @transmission
5 transmission ground @ body
6 transmission ground @ transmission
7 power steering ground @ body
8 Power steering ground @ power steering rack

I also exercised main circuit breaker a bunch of times

No more IMA light
No more check engine light
No more 12V battery charging light

Copper Anti-Seize Lubricant

torque specifications should be reduced by about 10%

I'm glad this worked for you this time. However, note that without performing an electrical resistance test, it is VERY difficult to visually determine if a particular ground strap is "good". They can look like crap and perform well... and they can look great and not work one bit.
