And google is my friend (again)
Here's a screen shot of my results
The big/long drop was when I was parked up on traffic survey duties; it was raining and I had to keep switching on to operate the wipers.
The upward curve after is overnight battery tender connected
I need to start logging exactly what's happening Parked - Driving - Charger connected - etc etc
My concern is that the terminal voltage falls away overnight down to 80% ish on a frequent basis - (in steps it looks like) - what causes this? (obviously alarm etc contributes...) but why the steps...
Cheers
Dave
