i have Cat 3196. Last week I had a salt water leak that sprayed the alternator, 70amp breaker, and starter. After cleaning engine and letting it sit for the week I started them up. Engine seemed to be running fine, but after an hour the engine just shut down. No warning, nothing. My ignigition breaker tripped and battery was to weak to restart. My question is....could the alternator be dead which caused the battery to drain, hence causing my ignition switch to trip to protect the ECM on the engine?
