I had to make the phone call of shame today.
Followed by the tow of shame.
Then the final push of shame.
I was driving in slow moving traffic when I heard a bang, when I opened the bonnet I saw smoke pouring out of the HV junction box.
There was no fire but something had obviously gone up in smoke.
After I got it home I found the precharge resistor had gone bang, something had gone wrong so it had been carrying all the current for the car.
Turns out a 5A fuse that fed a latching relay had blown. The relay was a safety net to keep the main positive contactor fed so long as the ignition was on but now it had a blown fuse the safety was gone.
Fuse and Resistor on the shelf of shame.

Thankfully the only damage was the resistor so after rewiring to prevent the issue happening again and replacing the resistor all is well.
