" The small red cable on the positive side of the battery cable broke off."

You might want to double-check your repair, because there should be two "small red cables" from Battery positive.

• One to the 25A fuse for the Fuel Injection

• One to the little junction box in the fender rail. This is where the +12 volts gets sent into the car circuits, including to the ignition switch and back out to the starter solenoid when cranking.

Of course you'd get no warning lights on the dash or anything if this 2nd circuit was bad. I just thought it was worth mentioning, since you had trouble in that area.
