🛠️ Service Notes
- Isolate the batteries before you start, and never disconnect the alternator or battery cables with the engine running — that will destroy the diodes
- Reconnect exactly as it came off, correct polarity, terminals clean and tight, and check the earth path through the mountings and engine is sound
- Check the pulleys line up and the belt runs true; renew a glazed, cracked or oil-contaminated belt at the same time and tension it by the procedure in the manual for your engine
- Support the alternator while you fit and tighten the mounting and adjusting bolts to the manual's figures, and never lever against the alternator body or end covers
- After fitting, confirm the charge warning goes out and charging voltage is correct, and recheck belt tension after the first running period
