Who or What group, came up this Electric System in these car must be a Sadist , or just plain had a sense of humor. Satterfield ,Thanks for reading}

 

Now, now, Mr. Satterfield, sir. The X-300 electronics package is pretty much the same as any high end car made these days. It is less robust than some others, in my experience, but with all of the convenience items, and the need for electronic engine control in order to meet emissions standards, the electronics are all pretty necessary!

Is there some specific problem you are addressing that I, or someone else, might help you with?

 

Except for an OBD system that torments me from time to time I thinks the X300 electrics are pretty good! I'm hard pressed to remember that last time I even changed a bulb.

Of course, this is after umpteen years of owning 80s vintage Jags that still used totally unsealed connectors throughout the car. What a mess. The up-side, though, was that about 80% of electrical problems were fixed with a tiny piece of sandpaper

Looking back at Satterfield's posts, he is having a problem with the instrument cluster blanking and not working in some way he is apparently too upset to verbalize completely.

Mr Satterfield. respectfully, chill, then read Doug's posts about bad ignition coils affecting the instrument panel. If that is not it, then you may have a bad IP. If you do, have a bad IP or connector. If you suspect a bad IP, then try another one. I happen to know where you could borrow one for test purposes.

 

Hi, Doug & everybody else. I meant no harm by my sarcastic comments, just venting as frustration level is high. The problem started when I changed the gear shifter J-gate (?). I changed it and took the radio & cooling and heating control systems along with clock etc. out. First problem, car would not start, I found a fuse was blown and changed it out and car started. However, I have no instrument gauges working, plus the cooling fan comes on immediately when the switch is turned on. I drove it about 25 miles to a shop and ask them to take a look, what they found was if they unplugged the instrument cluster and cranked the engine the engine would start then plug the instrument cluster back in the instrument gauges would work. They went over all fuses, and everything electrical and suggested I take it to Jaguar dealer to have it reprogrammed. I am assuming that he meant the electrical control systems. Drove the car home, and I tinkered with it for 10 - 12 hours. The only thing I have found was one blown fuse that controls the interior heal board right side #8 I think. (The clicking noise.) So I left the fuse out. By the way, Doug, I tried the coil packs last night and everything was great...no fireworks. Bottom line, I am still working at it and do apologize for my frustration & thanks for the help from all of you. If you can think of anything else I can try, please, please let me know. Sorry for the long post, but I guess that it was it took. Thanks again, Dennis

I'm still on my first cup of coffee so what follows is a bit generic. I couldn't begin to, let's say, look at a wiring diagram until my third or fourth cup

Since replacing the shifter seems to be ground zero have you re-traced your work in the console area? Maybe something was left undone, a connector not fully seated, something like that? From memory it seems like there are a couple big ground points in the console area. Any of those disturbed?

(I'm not disparaging you're abilities. If you went back and found something a bit goofed up I can positively promise that you're not the lone ranger. We've all been there.)

Next, what about the shifter replacement? Was this a used assembly? Seems to me there are a couple switches/modules involved. Did you swap over your existing, 'known good' shifter electrics?

Cheers

Good Morning Doug, changing the shifter was only for looks the other was cracked and looked ruff, i am now trying to trace my steps back to where i started, i was going to do that today,i tried the light coil thing ,everything was fine, i have OEM COILS , i took a magnafing glass and looked very careful, there was after market radio in the car when i got it, there may lie the grench , i will do that today, Thanks, Dennis Satterfield PS i have a extra IP i put it in tried it and same unplug and repluged and it works turn engine off restart no gauges ,

 

If you can remember which fuse blew after the original work, it might help to find what circuit has been disturbed. I think the story the techsa gave you about reprogramming the instrument cluster indicates their lack of knowledge or they just wanted to get rid of you and the Jag! There is little that could be re-programmed on an X-300, and nothing that I can imagine thatr would give symptoms anything like what you have.
As to the cooling fans coming on when the key is on, I think that is normal, assuming you have the modification defined by a TSB.
So, lets look at the data we have... A fuse blew after re-assemblY. Fuses seldom blow without a reason, so what was the root cause of the blown fuse? Then, what is causing the clicking noise? And what fuse did you remove to "correct" it?

My previous comment to "chill" was offered in complete appreciation for your level of frustration- I know myself I get frustrated after I have been stumped for a few hours. Some times it is better to step away and think about my next steps before I do something stupid!

This should actually be pretty easy to figure out , although it will take some time and testing.

 

Thanks for the suppport in all this, i will keep you all informed,as muggle through this stuff, Thanks, Dennis

 

The fuse was in the right side kickboard fuse box ,when i renewed the fuse, that is when the click started and i listen to about 3 min and it also had viberateing thumping it sounded like to me , i pull the fuse out and all that quit, i understand,it has to do with interior lighting, so, iam still looking, Satterfield

 

Was that the fuse you say was blown after you had the dash and J gate apart?

 

In fact yes,and i just came out my garage, i checked all and replace alot of them,still no gauges , car runs great, just no gauges. so, i am back to reading to see what i can learn, Thanks,Satterfield

 

And the plug under the dash that the tech wiggled to get it going? have you wiggled it again?

 

The tech. did not wiggle the plug after all,he said he unpluged the plug,left one, i did that and it started working i had all gauges,turn the eng. off and restarted it and no gauges again,i even had a spare cluster it was the same with it,so put the org. back in, same trouble,i have ordered a reader i hope that helps, i am still at it, Thanks alot, Satterfield

 

Hmm, wait for others to confirm, but it's starting to sound like a faulty Body Processor Module.

 

If anyone out their that thinks it is the Body Processor Module, i would like to here your thoughts on this, as for me i am at a loss to what to do , it is a very nice car low miles ect. I do not mind buying one if the probability is good, so please lets hear your opinion. many Thanks Guys, Satterfield

 

Hello Guys, I thought about one more thing in this mine bender thing, so this is it in a nut shell, on the battery cover under side near the battery ,i covered it with some silver covering ,not unlike fat mat or like that, and found two places, one near the + and one near the - , there were small burned spots on the post areas , i removed this at once and i have been thinking about this all night of what i have F----ked up. i want ahead ordered a body control module, i feel stupid, some what, Satterfield

 

Metallic?


'Fat mat' ? What's that?


If the material is metallic, effectively connecting the pos and neg posts together, yeah, that might be a problem! Lucky you didn't have a fire

Cheers

You are going to feel even more stupid when you realize your BPM is fine and you now have a spare!
