Keith’s Blog: The SCM Jag Becomes Another Roadside Attraction

Keith Martin Avatar

One moment, the 1971 Jaguar V12 coupe was hustling along at 70 mph on Highway 26, heading back to Portland after a satisfying lunch of fresh-caught rockfish at the South Bay Wild Fish House in Astoria, OR. The next, it was sitting silently, hood-up, by the side of the road. The Jag had been performing brilliantly. The 5.3-liter engine was spinning like a turbine. The a/c was blowing ice-cold. With the fresh OEM rubber suspension bushings, the car tackled the turns with gusto. The more power I applied the happier the car was. My second foray into the world of classic […]

    Ammeters display moments, voltments show trends and both deserve frequent attention as an integral part of your instrument scan. Normal operating voltages range from 13.8vdc to 14.2vdc so when its outside those numbers, a more thorough examination of the regulator, alternator and battery cables/clamps should be done ASAP.

    You are a lucky man Mister Keith, both for experiencing a daylight failure and for having Field Marshal D’Autremont on your team!

    This reminds me of my experience with a 1959 Jaguar XK-150 drophead. I bought the car from a high school classmate, I think for $1,000, (in the late 1960s), and foolishly decided to surprise my parents by picking them up from the airport in the Jaguar. On the way there, of course, the car died in the middle of the road. No immediate solution, tow truck called, went to airport in a taxi. The cause? Apparently a screw in the distributor had worked loose and disabled the ignition system. Of course, I later regretted selling this beautiful red Jaguar, which is probably worth a mint today.

    Keith, Maybe this is a good way to reach you. Since I re-uped my subscription late last November I have called your office 3 times to complain I was getting 2 copies of your great magazine, one to my home address and one to my office. I had put very clear directions on the renewal to please stop sending my copy to my office, to finish out the existing subscription to my home address and to continue the renewal mailings to my home address, no more copies to my office. Can you please make that happen.

    So what was up with it? (Obvs curse of Joe Lucas/leaking wire smoke but please be more specific). I’m feeling very smug at the moment having resurrected a dead starter motor on a 15-year-old Citroen with a £14 brush pack.

    Grace, space & pace. Better than the XK150’s I owned. Batteries in the wings behind the front wheels. No fun.
    I recently bought a Miata, killed 2 batteries by leaving the fob in the console. Dumb me. Dumb fob. We leave the fob in our Escape w/o that, so Mazda had that quirk.

    I had a 1981 12 cyl (Pre-HE which came out in 82) XJ12 Sedan. It consumed alternators and head gaskets with alarming regularity…The alternator problem was solved by substituting a one-wire 80A GM unit…with some heat shielding, The head gasket problem was corrected with a HUGE custom built Aluminum radiator that was more suited to California summers than the marginal original equipment, and a revised gasket set from Dolphin Coventry. You REALLY had to want one of these cars to drive it regularly. I traded it, with pleasure to Rich Ott when his shop was in SF for a nice Alfa 2600 Bertone Coupe. I think that was my last of a half-dozen Jaguars, finally got that out of my system. These cars were very cheap at the time (and still) for what they were…but they deserved the Lucas and Roots group/Leyland stigmas attributed to them. I applaud your persistence, but predict it reaching a practical limit…since I know you are an Alfa guy at heart, As am I.

    Ah yes, a return to The Dark Ages brought to you by Lucas and Smith. They should have supplied their speed dial number for your cell phone. Alas, Sir Neal was able to swoop in to the rescue. Kudos.
