How do you replace the wiring pigtail for the thermal transmitter on a 98 nissan altima?
It splices off the altinator and two wires run about 8 inches long to a conector with a little metal circle on it the circle hooks on to a post on the sensor coming out of the upper radiator hose engine side. The wires coming into the conector have seen better days andthe little metal circle broke out of the plastic housing.

Look for a loose output wire and connection. If the connection is loose dnd making and braking contact, it will blow the alternator. Also check the alternator ground, making sure it is not making and braking contact. The ground is the attachment to the engine bracket. You may have to add a large black wire from the alternator to the engine frame.
I believe that the splice for the cam sensor is about 8 inches back in the harness. Power to the cam supplies several sensors. I have fixed a few that the splice was bad, There is very little room to work in to get to the splice, but it's not impossible to fix.
I would probably get another connector or try to fix that one. The problem is the wires are soldered to metal tips that have clips to hold them in the plastic connector. In most cases once you pull the wires out by force you can not put them back and make them stay, the metal clips are broken. You can get replacement tips which is a chore to resolder to each wire, and chances are you may not have enough wire to cut and replace the tips. Or you can get another connecter with the wires already locked in and splice them into the old harness.
For the circuit to operate, it must have both battery voltage and ground. If there is battery voltage at the connector, then hook your test light to the Positive side of the battery and check for ground on the opposite (Black) wire. The washer pump grounds at ground # G-201. It is located behind the right sie of the glove box. There is also a splice in this ground circuit. It is located inside the main instrument panel wiring harness about 7 inches from where the harness breaks out and goes to the radio connections. (It could be a bad/loose splice)
Hello these cars were know to have a wire that runs from the positive on the battery terminal to the alternator that would corrode and cause this problem. The best way to find the problem is to remove the air cleaner box where the air filter is and then you will see the top of the battery. You will see a wire that is hooked into the positive on the battery terminal that should be green in color and if you follow it up it turns red. The green part of the wire is usually less than 6 inches. Right where the green and red wire connect together is where the problem is normally. You will probably see corrosion there. Cut the corrosion out of the wire re-splice it together and make sure any bare wires are wrapped up good with electrical tape. This should fix your problem. 4 thumbs up is appreciated if this helps.
here are a couple of quick easy thing to do to isolate what the problem is. if your battery is new and fully charged. then take a set of jumper cables and put one clamp on the negitive post of the battery and its corresponding clamp on the alternator bracket on the motor this will insure that you have a complete ground which you need to ingauge the starter. in dc current the amperage is constant and the voltage is variable. a good ground is needed.
if the charge in your battery is depleted jump the car to get it started. then remove the positive cable from the batteries possitive post if the car stays running then the altinator is charging this illiminates the alternator from being the problem. if the car stays running its good if the car dies then the altinator is bad and needs replaced.
check the wires hooked to the starter to make sure that they are not gounding out on the block or the exaust.
one thing at a time ant first on drivers side next to gas pedal right above it they are a box maybe 7 inche long maybe 3 inches wide made of metal with a wire plung on the side then on the top of box ant plugs into it after u take the little hanger off i think its a 7 or 8 mm socket and wiper prob u need a wiper motor try running a ground from body to the wiper motor if that dont work u need a motor
there are several ways to do it the first one that comes to mind is to get a toggle switch tg7000w is napa auto parts part number if not napa make sure its rated 50 amps or higher above is 75 amps
get some 14 guage or larger wire but conectors un hook your battery splice into the red wire that plugs into the distributer run your wire hide your toggle switch and there you go please leave feedback thanks
