No, I haven't tried anything yet, not had the battery on the car. And it's ruddy cold here :-)

Haha isn't it just! I've just washed my car so you don't have to tell me, I'm typing with semi frozen fingers and not the fish type either. Until you try comfortably numbs suggestion there's not much else to add that I can think of, but I'm not the best with auto electrical issues.

As explained before, the alternator can continue to produce 14V, but if there's a leak, it drains out of the battery, via the diodes. Diodes are only supposed to allow current to pass one way, like a one-way valve, that is how they rectify the alternating current (AC) to Direct Current (DC) for the battery to store. Once you switch off the engine, and the alternator, the full battery slowly drains back through the faulty diode(s).

Thanks. But surely I would be able to measure that with my amp meter.
All locked up, the car is drawi g around 18 milamperes (if I remember correctly) I'll recheck this weekend. This is why I'm wondering if the battery is not being charged. The first time it happened was after a 600 mile run to the UK. The battery was dead the next day. Pete. |
