This is a little different than the other 100 threads on the topic. My 2014 p85d with an early 2015 pack is down being repaired - this is detailed in other threads. The pack has the original wire/ceramic fuse that was working fine - not the pyro fuse with the onboard battery that is triggering all the service alerts. When I put the pack back together should I reuse the low-tech fuse that was in there or 'upgrade' to the current pyro fuse being installed by the SCs? I've already checked and of course, they won't sell me one anyway, so if the consensus is to upgrade, what is the part number to google and/or does anyone know of a vendor selling these unobtainium parts?
