Question about 1999 Mercury Cougar
Hello, I'll start from the beginning
I recently purchased a 1999 Mercury Cougar 5spd Manual with 126k Miles and in pristine condition. 1 Owner, took wonderful care of her.
Her upgrades consist of a K&N Cool Air intake, Venom ECU piggyback, X Rear 1.5" alloy sway bar, and a catback exhaust, Ford Racing Sparkplugs and no clue what else. -From what i have found-
While driving from WA to AZ cruising at 80mph in Cruise Control, the car chugged, Lost all gauges, tac, odo, and MPH included. Car ran just fine for roughly 500 miles before we reached our next checkpoint, St George, UT. We brought the car to the Good Ol' Boys mechanic shop and got the problem diagnosed as a Speed Sensor going bad, had it repaired and the car ran like a top once more. After leaving the shop i pulled up to a Sonic for lunch stopped the car, went to start it and... NOTHING. Dead. So we cleaned corroded acid on the battery terminals and reconnected the Battery and whala!, problem fixed.
Well roughly a Month has gone by with no problem until the other night while cruising at 55 on a hwy, the gauges went haywire, my traction and ABS lights came on and started flashing, and the car went kapoot. Lost everything, wouldn't start, emergency flashers barely blinked ect.
Pushed the car over to the shoulder, played with the terminals, then turned off the Venom, and it started. Made it a whole block before it happened again. dead. **Interesting thing occurred when playing with the terminals. The radio turned on with the keys removed and the door open. ?!?!**
A friendly guy stopped with his truck and provided us with a jump. car ran just fine for roughly 20 secs after the cables were removed then took a poo again. He provided us with another one, and this time, once we removed the cables the headlights dimmed massively then everything shutoff after about 5 secs. we pushed it to the gas station and i got it towed later that evening. *highly recommend spending the $7 extra or w/e on your INS for roadside assistance, really comes in handy on those $200 tow bills**
The next day we went down to jump the car. After inspecting the K&N we noticed the Negative battery cable is rubbing against the Metal Mesh frame of the filter and the cable is bare. A friend noticed it smoking when we had the problem the night before. We put a rag between the metal mesh and the cable and the car started with no problems. hmm? it drove about 1/4 mile before dying again. Jumped. went for about 1/8 mile, died again. Jumped once more and it went about 1/2 mile, and then it died as i was parking it. While cruising down the road, when it was starting to die, the whole car chugged and jerked vigorously. SO we went down and traded in the old battery for a new one, old one was dated 2004. Put it in, and car runs like a charm. Come to find out, the Battery Voltage Sensing Fuse #7 was blown so the light never came on.
The car has started just fine, we taped the negative cable with electrical tape for now, replaced the fuse, and after a day of driving, the fuse has blown again so that when you turn the key to accessory before starting, the light does not show on the instrument panel. We purchased some more fuses and replaced it again, tried using all accessories in the car besides cruise control trying to blow it to see what wire we need to look for that might be causing a short, but are unsuccessful so far.
Does ANYONE know what the Godforsaken root of this annoyance is?
Other than its a FixOrRepairDaily
