2001 Prius with 230,000 miles, replacement hybrid battery in January 2009 at 197,000 miles has recently been having mutliple electronic problems. Current status is: o Disconnect the 12 v battery for one or two days. o Re-connect the 12 v battery. o Turn key and the ICE starts up and runs normally for about 20 seconds, but all warning lights are on: Red Triangle, PS, ! Car. o ICE begins to shudder and shake as if it is attempting to engage something that won't turn. o After about 15-20 seconds of shudder/shake the ICE dies and nothing will happen until I start over at disconnect of 12v battery. I am guessing that the ICE is trying to engage the motor/generator that recharges the main battery, but it is stuck. Is that what is called "the inverter"? I appreciate any help or suggestions about how to solve this problem.
