Fault Case & Solution
Problem: A Caterpillar 345D excavator (S/N CJX00567) showed erratic voltage, warning "HI VOLT", then shut down.
Root cause: Internal short of the 9X-9591 transformer assembly caused 32 V surge, damaging the ECM 5 V rail.
Solution: Replace with Growshine genuine 9X-9591 9X9591, re-calibrate ECM parameters, re-test alternator; machine returned to production in 4 h.
