new to the site, new to the cars, have some Q's
Well, My name is mike and i just picked up a 1990 Jaguar XJ6 in IL. I didnt have any intention on buying a car while i was down here, but this came along and i couldnt say no. The only problem i have is the battery light and a few others on the left side,as you are sitting in the car, are on. One being the battery, ABS, blown bulb(i think) and low washer fluid which i haven checked any of these yet. The can has a new alternator and ballery in it. I havent touched the car since i got it home. The thing that kinda worry's me is the blower motor dosent work, and the guy i bought it from said that every now and then, the blower motor will kick on and the battery light goes off. Does anyone on here have a wiring diagram that they can post, or has anyone else had this problem? Any help to a new owner would really be appreciated.
thanks,
mike
thanks,
mike

RE: new to the site, new to the cars, have some Q's
I'll post a few links here and you can study them. You have a Delanair MK-3 "climate system", which is different from an A/C system in that the compressor comes on all the time, (even in winter when using the heater), to de-humidify the air.
1) here's the first link about the Blower problem: It has to do with the "Darlington Transistor" and the location where it is, most do-it-yourselfers change the location of the circuit boardafter replacing the transistor.

2) here's the second link, more detail about the MK-2 system (up to 1987) and the MK-3 (from 1988).
http://www.jag-lovers.com/books/xj-s/14-Aircon.html
3) there's a guy who hand-manufactures an improved circuit board with a new transistor, and if you want to go that route, I'll send you his e-mail and you take it from there.
good luck!
Jose

RE: new to the site, new to the cars, have some Q's
it must be an XJ-40 because Series 3 XJ don't have any "information button" likeXJ-40s do.
as to Washer fluid, try agua, nothing but. Those "blue" windshield water fluids cause problems, like staining the paintwork, like clogging the check valves and the washer motor. I always use agua and never have any problems.
also, he describes thefan/blowercoming on by itself after he turns off the ignition, that's typical XJ-40 Delanair MK-3,not Series 3 XJ with the Delanair MK-2. (Ken, aren't you happy we have Series 3 XJ ??)

RE: new to the site, new to the cars, have some Q's
Also, the car will not charge. I had the alternator checked with it in the car and running, no good. Pulled the alt. out and brought it in to Auto Zone to have it checked, good. I replaced the main power wire with one and ran it all the way to the battery, nothing. Is the voltage regulator built into the alt or is it the little box the brown wire goes into off the back of the alt.?
thanks,
mike

I'm not familiar with that year's alternator - but Ken is. he sellsthousands of them.
modern alternators have the voltage regulator usually built-in. I would take it to a specializedalternator shop and get a second opinion. Anytime you replace an alternator, you need to replace the battery too. why?

RE: new to the site, new to the cars, have some Q's
The short answer is overvoltage protection. It helps the stablize the charge from the alternator to a constant over the system. It gets in to all sorts of bus voltage that is much lower than the 12 volts in an automotive charging system. With the advent of solid state electronics in cars this becomes far more important. It can wig-out (not a techincal term) and drag the entire system down.

RE: new to the site, new to the cars, have some Q's
cool. Are these cars half way easy to find in a local junk yard? Also, is there other years that has the same modual? Do you know of anyone that has one for sale for cheap? And if not, can they be repaired? We have a local place called the GEEK GROUP. they do anything and everything with electronics. If they can be repaired, then would that be the way to go? Sorry for all the questions, but i doo really appreciate your help with this mess.
thanks,
mike

RE: new to the site, new to the cars, have some Q's
there are salvage yards that will have these cars, or any other year. Another place to check is on eBay. But you'll need to check if that part is exactly the problem - don't replace parts without being certain they are bad.
To answer your question about repairing parts like Relays, Modules, and things like that, I would tell you go ahead and try, what have you got to lose?
But again, are you absolutely sure the part is bad ? In my two old Jags, (1965 and 1984) all relays, modules and such are openable, serviceable,and repairable. Yes sometimes it takes a geek to repair them. Butif they can repair them, all the power to them.

RE: new to the site, new to the cars, have some Q's
the only body kits I know of for the Series 3 XJ-6 are made in the UK, as shown in the pictures below.
The owner of the car below is Steve Fuller - contact him at http://www.skjagtech.co.uk and maybe he can find you a kit.
