I picked 393 up in Idaho in early Sept 2018 and drove to Provo, UT to discuss some changes I hoped David Kirkham would make for me. A pal of his with a side pipe falling off his 38,000 mi 427SC. He suggested David remove the Lucas toggle switches as he had had many problems with them in his car. It was done.
Being a new owner and pilot I watched the temp gauges like a hawk but it was cool in UT and no issues observed. On leaving Kirkham’s new magnificent factory I was on a slight upgrade on the main drag North with a car in front stopped at light. It started drifting back, I hit black horn bottom on dash and NOTHING. I yelled STOP PLEASE and the driver obliged. Horn did not work again and I didn’t know it was also on the fan fuse. I had David add to his list for me. I’m now wondering if I had an operating cooling fan for the remaining 350 mi. of 600 we drove before retuning car to Kirkham.
This morning we replaced the blown 25 amp MDL slow blow with a 30 amp AGC. Also disconnected horn wire from horn/fan fuse block. Have driven 50 mi. and fan still working. I also had David add a temp switch to make sure fan would automatically run if I left toggle OFF. It’s an age thing. The fan/horn relay is not LUCAS, but Improdus PRZEKAZNIK T80-70 12V 75 A .
