I wondered about the OAT stuff but decided against it after reading up about it a little. Seams that it (could) cause some kind of internal corrosion if I remember correctly. Didn't think it worth the risk.
 
Random question -why would my aux alternator be warm when the car hasn't been used since midday? It was used for two minutes and not moved since. Aux battery voltage is down to 11.56v!

Confused!!

It's done it again! :mad::mad:

Moved the car on the drive - 50 feet max - and an hour later the aux alternator is hot again! As hot as day to day driving. Took off battery cable and it's cooled down and stayed cool when the cable went back on! :confused::confused::confused::confused:

I reckon you've got a faulty alternator which is take juice out of the battery, which is why it's getting hot.

Does it make any noise when it heats up? The wiring isn't mixed up somewhere and the battery is trying to turn the alt when the relay turns off?
