Just wondering if anyone could help with me a problem I have. I recently purchased a 1985 Daimler 4.2 (series 3). Beautiful to drive and to look at. However, I appear to have some sort of a problem with the charging system, but I'm not sure. With the engine running, the battery condition indicator does not always read 13 volts or above (as its says in the manual). It frequently drops down into the red discharge area of the indicator or close to it - 10/11/12 volts. It can remain there for several minutes and generally will eventually revert back up to 13 plus volts. This is a little disconcerting at night (particularly when the dashboard lights start to dim!). The car has never failed to start (unless sat there for a period of time), but does appear to be a little slow to start sometimes.
I have had the battery, belts, alternator and connections to it checked by garage. They are all fine. Any ideas as to what might be causing the problem or perhaps this is usual and nothing to worry about? I noticed that someone had posted comments stating that problems with voltage regulators were problem with these cars. Perhaps that's it? Any help would be much appreciated.
I rescued an 86 XJ6 back in September. It cost me about 800 bucks. The second I test drove it, it was clear that this car needed me as I needed it. Unfortunately saving this beauty required me to rip out the old engine. Like one of the other posters, I noticed water and antifreeze mixed in with my oil. The rings looked like a dog chewed on them for months. Bottom line, I dropped a new engine in it and am waiting impatiently for the opportunity to see it in action.
I bought a new 1983 XJ6 when they hit the showrooms and drove it for eleven years. I had a multitude of problems including AC, steering rack, fuel hoses, fuel pump, fuel change-over switch, etc etc... I must not have learned my lesson because I recently purchased a 1985 XJ6 at auction, which is now in the Jag hospital because of various ignition problems, including a very deteriorated distributor.
Parts are difficult to find... Repairs are expensive... The acceleration is terrible... BUT, I would rather ride in a tow truck pulling a Series III Jag than drive a Cadillac...!
I agree with the sentiments expressed here. I have lost hair, sleep and chunks of paychecks over these cars. When they run and run well... PRICELESS!. There is no replacement ride for a Jag. Cheers.
