1995 Defender 90 300 Tdi PU Coniston Green

None start

Hi all, here goes my mate had a shot of my disco for the weekend so I was using his td5 defender and I parked it up on Monday and left it for half an hour and when I went back to it it wouldn't start it turned slowly then went dead so I put some jump leads on it and away it went so went back to my house (10 min drive) turned it off and tried it again still nothing so I put the charger on it low over night and in the morning it started about 3 times then it went dead again so I checked the voltage while running was at 12.5v slowly dropping, so check the earth to the battery that seamed fine, checked the plug on the back of the alternator gave it a wee clean, then tried a known good battery of my motor but it did exactly the same thing and the starter seams the be turning free enough, so would I be right on saying it needs an alternator?

Cheers

Yes. Or at the least a voltage regulator possibly. Rhubarb and custard let fly with their secret weapon.

Check the nut on the starter motor (where the main battery cable connects on to) isn't loose... a common fault, giving "flat battery" symptoms.

NOTE: i'd disconnect the battery first before you try to tighten up said 13mm nut, lest you touch any part of the engine/chassis/earth point with your spanner, as it'll lets the sparks out.
