I couldn't find the fault so it ended up on a tow truck. This morning I had clearer head and got it fixed.... but without finding the fault! This evening I went to a Landrover club gathering and on the way I broke down again! This time I found the fault and all is well. The fault was simply a loose connection on the coil. The connection appeared to be OK visually but when I touched it, it was not secured.
It was 7:30pm when I returned home and Naomi had already done the nighttime routine for Kaylia ...... but Kaylia soon emerged from her den .... and insisted that I had to do the routine again!
