The car is now back with new fuse box, new wire to the alternator and new wire to the battery. I have done a load test with front screen, rear screen, full fan and lights on. This is what was on in Fr when it died. The alternator cable gets nicely warm, but the links in the box get hot. The hottest is the one next to the alternator return which is slightly charred from before. I am going to send it back to the gge and ask them to replace that too. Should any of this even get warm? That sounds like a one way street to burnt cables over time to me. Anyone know? Thanks Graham
