Brave? My hand was forced somewhat as it started giving a brief flash of the right hand bank slow down lamp followed immediately by a brief flash of the check engine lamp although the engine continued to perform without any apparent problem - rinse and repeat at varying intervals of time between 10 and 30 seconds. This took an age to diagnose as a voltage drop across the main fuse/relay board which resulted in all the extraneous additional wiring being removed which then fully uncovered the dire state of the board. Deep breath required followed by requirement for deep pockets!
