1. Pulling the plug disconnects the alternator's charge sensor, therefore - no ignition light!
2. Is your fanbelt tight / clean / in good condition?
3. Is your wiring in good condition?
4. Are ALL the battery connections tight?
5. a: How old is the battery? (more than 18 Months - get it checked)
b: Is the battery a 'calcium' type? (Known to have intermittent problems after alternator faults)
There are other items, but eliminate the above first!
