Tried to check the shut down procedure of my truck..
Few photos which highlight some points..
The blue trace is current, the red is battery voltage..
The time base caters for about 7 to 8 min..
I had the current clamp on 20 amps and it was out of range with the engine running..but once switched off was fine for what I wanted to look at.. Suspect the glow plugs were active which would account for the high current initially
Takes about 45sec for the current to drop to about 75/80ma after locking the truck..
The thin narrow current spikes are the remote fob been used for lock and unlocking..
One of the advantages of the scope is you can save and analyse the traces after you have them stored..
Here is one looking more closely at the min level of the current.. Using a couple of rulers which you can pull down
