Alternator???

[DaddyA]

Hi,

well managed to get in the garage and have a look.

3 terminals on alternator. (1)Large red to battery. (2)Middle terminal goes to warning lamp. (3)Last terminal goes to relay?

Have have put a bulb between 2 and battery - lamp illuminates. Same with 3.

Connected 3 directly to battery and wired up 2 with a power supply.

Position 0 & 1 on ign and lamp illuminates, position 2 and the lamp goes out.

Position 3, engine starts and alt kicking out 13.5+ volts.

When eng stops, battery warning lamp back on, even with key removed.

Getting there, slowly. Smaller cable to battery seemed to get warm???
