This morning I managed to find a dealer that specialised in ex-military Land Rovers and he had a 65 Amp alternator in stock which he has put in the post to me today. I'd spoken to the army electrical engineer earlier and he gave me some back-of-the-envelope figures to work from:
Firstly, the original military alternator was 48 Amps, not 60. However, the civilian one I got to replace it was indeed a 35 Amp one, so wouldn't suffice.
Now, we 've added various electrical components which he provided the rating for:
If we assume the basic electrical system requires up to 30 Amps to operate, then the 65 Amp alternator adds 35 Amps of capacity which will give us enough to run all of the components we've added, but obviously not all at once.
Bottom line: it will suffice so long as the operators are sensible about what they run and when. The nice thing is that the Truma inverter is an intelligent system which will stop supplying 240 Volts if the battery charge gets too low, so it will literally be impossible to discharge the battery by over-use of any of the 240 Volt appliances. |
