Hi Dave

Interesting Capture, I don't think you could condemn this on voltage alone...

Applying the loads at Idle may also give you a false reading, I would like to see the load applied (using a Carbon Pile tester) and monitoring the current output at around 1500- 2000rpm and then at idle....

Also what does the voltage do with the three pin plug disconnect?

Interesting to see you got 2 channels missing... I would like to know what you are monitoring on channel C, or would that give the game away???

In this instance is it possible that a component is dragging to much current when applied and the alternator is not coping...??

Thanks for sharing this sounds like it going to be the unexpected.......
