So something I saw some time ago on Muxsans twitter, was a HV cable with some water coming out of it. Link here: https://twitter.com/muxsan_ev/status/12 ... 09/photo/1
I didn't think much about it, but then I ran into the same thing on a customer car
If this gets really bad and enough water gets in there, I can see how this causes isolation fault codes. Maybe this will be a hot tip for someone in the future facing isolation faults?
