    my 93 markVIII on dash said cooling system needed checking(litterally after a spoonful of water it stopped), the next day it saidcharging system needed checking.....after this if the car goes above 800 rpm the a/c shuts off, if it falls below it comes back on. Also the air bag light comes and goes (off & on). all along, when accelerating it was missing and sputtering, but i can give it a fair amount of gas and it goes? i was told TPS(throttle position sensor) but, no luck. (by the way, that was fun to change) since then i smelled electrical burn smell (again). and now the air ride system isn't working....It has to be electrical, but i can;t find a manual for this car anywhere, so i can try something else. any help would be greatly appreciated. (grandmother bought this car new, and gave to me a month ago, car is in excellent shape and 72,000 miles. chuck

Grounds, yes. There's probably 100 of them
Alternators: no (maybe).
Little known fact (Check the MarkVIII forums) that if you are running around on a weak battery, you WILL ruin your alternator. I wondered this while I replaced my THIRD one in a year on one of my Marks (I have two 1994s, one I race)
Most rebuilds are junk from discount stores anyways. The Mustang Cobra 96+ has basically your same engine but the alternator is different. It looks almost the same, though. get one from an alternator rebuild shop. It might even be cheaper than the chain stores (Mine was $85 from a place in West Allis, Wisconsin)
Ground problems are the hardest to find. Mainly because there is a section in the manual that tells you where they all are. The Manual is on a CD and can be had on eBay or other places online for under $10 (because they are pirated). I dont know what a "legal" one costs.
I'd take it to a dealership and offer them 2.5 hours labor or $250 total to fix it. That would be cheap, as these problems can be nightmares.
Check to see if these circuits are on a relay (located anywhere, also a box under your hood) or self-resetting circuit breaker (they look like rounded metal things in your fuse panel).

First place to start, check the ground on your battery and make sure it is making full contact. Also check the negative and make sure it too is making full contact.

Why does my altenator get so warm and charg at 11.55


I would take your alternator to an auto parts store that does free alternator testing. That will give you a definitive answer if you should replace or keep looking for an electrical problem.

WHAT CONDITION ARE YOUR BATTERY CABLES ? THEY MAY SEEM OK, BUT SOMETIMES REPLACEMENT IS NECESSARY ! BATTERY TERMINALS MUST BE CLEANED, SMEAR SOME VASOLINE ON TERMINALS BEFORE MOUNTING THEM, BESURE TERMINALS ARE TIGHT !!! THE (NEGATIVE) CABLE OR GROUND IS VERY IMPORTANT ! A GOOD CONNECTION IS PARAMOUNT !!! INSPECT STARTER/SOLONOID CONNECTIONS, THEY MUST BE CLEAN, PROPERLY CONNECTED , TIGHT !!! TIGHT IS TIGHT, TOO TIGHT IS BROKE !!! MAKE SURE BATTERY IS IN GOOD,CLEAN CONDITION, FULLY CHARGED !!! YOU DID REPLACE THE STARTER WITH A NEW SOLONOID I HOPE ! ITS THIS ELECTRO-MAGNET THAT INGAGES THE STARTER INTO THE FLYWHEEL TO CRANK THE ENGINE . THEY WORK TOGETHER ! TAPPING ON THE STARTER TELLS ME, POSSIBLE LOOSE CONNECTION, EITHER INSIDE OR OUTSIDE SOLONOID . ALTERNATOR PROBLEM ? TAKE TO AUTOPARTS STORE, HAVE THEM CHECK BOTH THE BATTERY & ALTERNATOR . ITS FREE ! CHECK THE ALTERNATOR BELT FOR WEAR, WHETHER ITS TIGHT, LOOSE, ETC., A WORN OR LOOSE BELT WILL SLIP, NOT ALLOWING THE ALTERNATOR TO DO ITS JOB, CHARGING THE BATTERY !!! ONE MORE THING, ITS IMPORTANT TO KEEP THE ENGINE TUNED-UP, ESPECIALLY BOTH AIR & FUEL FILTERS, SPARK PLUGS & PLUG WIRES SHOULD BE REPLACED AS WELL, THEY DO WEAR OUT !!! DISTRIBUTOR CAP & ROTOR NEED ATTENTION ALSO, REPLACE THEM ! BACK TOO YOUR SRARTER/SOLONOID, SOMETIMES EVEN NEW ELECTRICAL PARTS GO BAD, IT HAPPENS ALOT, THEY COME FROM MEXICO, CHINA, ETC., NEED I SAY MORE ???

I have burned through three batteries in one year. I think i have an electrical drain on the battery. once its jumped, it runs perfect. doesnt seem to hold a charge. the alternator and starter work fine....


You need to have a technician familiar with car electrical systems check for parasitic drain. This can be as simple as a vanity mirror light or glovebox light remaining on all the time.

I think my car is possesed so I call it Christine. Every week something is wrong with it. I dont get one thing done and another happens. Alot of electrical items. I have replaced my alternator two times in...


Not to knock the ability of the mechanics where you have your work done, but with all the electrical problems you're experiencing, it would be money well spent to take the car to an electrical specialist. He can track down shorts and maybe get a lot of your issues fixed. In the future, when service is needed, a ASE qualified mechanic is well worth the money.
Spending a few dollars now could ensure that in a few months you will own a good running car with no car payment. Best of luck.

96 Jaguar xj6 Electrical Issues


I forgot to mention about the locks. Mine does the same thing...jumps three times. This is an indicator that one of the locks on the circuit is not functioning properly. Mine happens to be the right front but it could be any door including the boot lid.

The antenna could be a burnt motor; however, my 1987 XJ6 had the same issue. One day it came up just a bit and I was able to slowly coax it fully out. After I got it out, I took some olive oil and lubricated it just a bit--not a heavy lubrication--and it worked well after that although it would still sometimes stick.

Front passenger seat jammed


I would guess that something might be jammed in the tracks or it is an electrical issue. Sometimes the connections to the switches are bad, sometimes the switch itself is bad, and sometimes the moter is burned out. Listen to hear if the motor is running, if so, check the track and see if it is jammed. If you don't hear anything you have some electrical tracking to do.
