That exact thing happened to me on my ICE Pantera. I wired the cooling fans with an Auto Zone inline 30A fuse and the Auto Zone relay that I used to trigger it blew in the closed position. The constant load heated the plastic and burnt the fuse holder without blowing the fuse.
Now I use a fuse in a Siemens block mounted on the bulkhead with a Bosh relay. I figured I got what I paid for. sean On Mon, Jan 4, 2016 at 10:18 PM, Jay Summet via EV <ev@lists.evdl.org> wrote: > > > On 01/04/2016 09:59 PM, Lee Hart wrote: > >> Jay Summet via EV wrote: >> >>> Has anybody ever melted the plastic and holder of an Automotive ATC >>> fuse, without blowing the fuse itself?
