I have just repaired the second seeming wire failure with my BN7 since I acquired it a year ago. This car had had a very extensive restoration, not a body off frame, but it has a great many parts replacements and upgrades. The first failure was the right front "sidelamp," what we Yanks would call a parking light. It worked, and then it didn't work. Though I have done a lot of automotive wiring--i've successfully done simple DIY chores like installing a VDO voltmeter and a cigar (really, a GPS) lighter. But I'm not really knowledgeable beyond reading wiring diagrams and simple circuit testers. I deduced that the wire from the light switch to the sidelamp had expired. Rather than trying to find a break in the wire inside the harness, I simply ran a new wire. Fixed. More recently I found my left turn flasher (turn signal) was doing a double time and the left front bulb filament was not lighting. The parking light filament, however, did. I ran a test wire from the proper pole on the flasher box to the turn flasher bulb contact and the bulb resumed functioning. So I replaced the flasher to bulb socket wire--it's only about 14 ". It remains puzzling to me that these wires would fail during a relatively uneventful life--well, I did drive it more than 400 miles to the delightful Brit car show near Tampa in November and back here to near Jacksonville. So, it's a 53 year old car, but I didn't have anything like this happen in seven years on my '62 Jag Mark 2, on which I did considerable electrical work, electronic ignition, radio speakers, third brake light, electric brake light switch and driving lights . In both cases with the Healey, I think I accurately deduced that the wire had failed. Have others had this happen?
