Sorry for the lengthy reply, but there were a lot of questions to answer...
<span style="font-style: italic">"Except when the ground connectors simply snap and fail....They bolt under things, ground bullets slip into the "curls". The "curls", after almost 45 years, simply snap."</span>
<span style="font-weight: bold">They last for 45 years and you consider it a poor design? Do you really think a new Toyota part will last that long?</span>
My Flathead Fords are over 60 years old, haven't lost any grounds. Original starter button, door lamp switches, headlamp switches.....
<span style="font-style: italic">"....on my Jag, there are these red "Lucas" jobbies off the parking lights that light when park or headlamps are on. Know why? So you know if your rotary headlamp switch made contact"</span>
<span style="font-weight: bold">Incorrect. The lamp is to let you know the running lights are on.</span>
Sorry. EVERY MK2 I have seen, they are on with park and head lamps.
<span style="font-style: italic">"How many wires to the votage regulator on your XK120?"</span>
<span style="font-weight: bold">I don't have an XK140, but your question depends on whether or not is uses a 5 or 9-post control box. Not sure what the point of the question is anyway.</span> :confuse: It take as many wires are required to run power from the control box (voltage regulator) to the various systems.
All my flatheads have max 3, which is 2 or 6 less possibilities of corrosion or failuer issues.
<span style="font-style: italic">"Bad connectors and grounds ARE Lucas, and if they fail, that's Lucas."</span>
<span style="font-weight: bold">That's like saying the engine in a brand new car is garbage because it failed due to lack of maintenance. A bad ground is not the fault of Lucas, it's the fault of the owner for not maintaining their vehicle. Metal will corrode, especially in salty or wet climates. Trusting that an electrical ground will survive for 40-60 years exposed to such conditions with no maintenance is rather illogical, don't you think?</span>
We're talking British cars.
In 45 years of working on cars, do you know how many times I have had to deal with bad grounds on other than British cars?
<span style="font-style: italic">"When is the last time you used your windscreen wipers?"</span>
<span style="font-weight: bold">Last week, in a winter storm at 7,000-feet. Don't assume that because I live in California that I never leave my warm, sunny driveway!</span>
Just checking.
<span style="font-style: italic">"Most folks I know in LA don't drive their "classics" in any kind of dark or inclement weather."</span>
<span style="font-weight: bold">I agree, but I'm not one of them. I drive M.G.s daily to work (through several counties) and for travel. I've driven all over the states in them. I've even driven on the salt flats. Do you know how much salt gets packed into every nook, cranny and system of the car when you do that? In the near future I will be driving a 1949 M.G. 10,000 miles around the entire continent. And you still think you're harder on your Jaguar than I am on my cars? :wink:</span>
Absolutely.
And my Flatmotors.
Haven't done the hundred-mile-dirt-and-gravel-road trips with the Jag YET, but I have taken the flatheads places 4X4's fear to tread.
<span style="font-style: italic">"The chances you have had to depend (as in USE them to get home at 0200) headlamps, panel lamps, windscreen washer, heater motor or defroster motor (and associated switches) are little and none."</span>
<span style="font-weight: bold">Excuse me? Why would you assume that I don't drive my car at night? Rather narrow-minded, I think! Yes, I drive my M.G.s at night EVERY night, sometimes far from home in the middle of nowhere and sometimes in the city. And many, many times in torrential downpours with water above the door sills.</span>
A) Because you live in LA, and B) because you live in LA.
Thanks for the update.
<span style="font-style: italic">"I know when I took my 1950 Ford out from California to South Carolina in 1972 while in the Navy, I discovered the need for a new vacuum wiper motor the first week. Never needed it before."</span>
<span style="font-weight: bold">Of course, since you apparently never used the wipers in California! LOL!</span>
First, didn't really have to.
But, I did learn the flying trick, to drive PAST the windscreen.......now, with British cars, I don't have to worry.....
<span style="font-style: italic">"So, in damper climes, when older, there are issues. Not insurmountable, but issues nonetheless."</span>
<span style="font-weight: bold">I agree. Wet climates are harder on old cars.</span>
<span style="font-style: italic">"(ever looked at the field coils on an older Lucas starter motor?)"</span>
<span style="font-weight: bold">Yes, when I replaced the brushed in my TC a while back. Despite the mileage on the car, they were original 60-year-old parts. They had worn completely through and were still functioning. I love Lucas!</span>
