What causes a car battery terminal to get hot when trying to start it?
Possibly this1. If wires get hot when you try to start it and the motor is spinning over. Then the motor isn't starting and your over heating the cables by using the starter too much.2. If the wires are getting hot, but the engine isn't turning over then the starter is bad or the BIG wire going to the starter is shorted.3. If only one wire is getting hot at a connection, then you have a bad connection at that point. A symptom of this problem is everything electrical shuts off when you hit the starter.
Can someone tell me where the starter relay is located on a 2005 nissan sentra?
Some time you can tap the starter with a 3/8" extension and hammer while some one is turning the key. That jars the starter and it may start the engine. Nissan remanufactured starter is your best choice. If you replace your Nissan Starter and give your core away then have a problem with brand X starter you will loose 100 dollars or more. Manual trans uses a clutch relay automatic uses a PNP park neutral park relay. Both relays are near the battery under the hood. I have replace lot's more starters than relays. Good Luck
What problems go along with a bad catalytic converter?
A clogged catalytic convertor causes the symptoms of a loss of power when accelerating or going up a hill. This is an often overlooked cause of loss of power, can cause check engine fault codes and lights, and mechanics will often change a few parts unnecessarily , especially if it is only partially plugged. A couple ways I check for plugged cats when a low power complaint is a symptom, and other obvious basic maintenance items have been checked for service is to have someone hold the rpm at about 1800 to 2000 steady. Then check for a good push of exhaust with my hand from behind the tailpipe. A plugged or partially plugged cat typically leaves a hot sickly feeling exhaust flow from the tailpipe. Compare to a known good working car nearby, known to be performing properly and with the same amount of cylinders. That slow , hot sickly flow at 2000 rpm compared to the hard push blowing your hand away of a not clogged cat is a dead giveaway, and I have NEVER misdiagnosed a plugged cat , or made false diagnosis with this method. Another way is watching a vacuum gauge connected to the intake manifold. When revving up, if the exhaust is plugged the gauge reading will climb then begin to slowly drop as the exhaust pressure builds up. Further testing will be needed to verify which part of the exhaust is plugged. Diagnostic by codes is unreliable and until now I had not heard of it. A code p420 only refers to catalyst efficiency. And can be set by faulty o2 sensors. Removing the exhaust and testing for engine power returning to normal works. But the hot sickly flow has been most accurate with my experience, in several cases where shops had missed it, were stumped and called me to come check. They are always embarrassed for missing the simplicity, but need not, as cars and their complicated electronics and even age old problems can lead to loss of power without any immediately obvious cause.
Will a car jump start with a bad starter?
How to Start a Car with a Bad Starter?The tips described below are the best possible ways to instill life into a dead starter. Try them one by one until you find a solution.Check the ConnectionsThe starter is an electric motor and a part of an electrical circuit. It sets the engine of a vehicle in motion. So, the engine won’t respond if there is an issue with the battery or the connections. Check the joint of all the connecting cables between the battery and the starter. Tighten everything because a loose connection means less flow of current to the starter.Check the starter for loose connections.Clean the CorrosionCorrosion could also be the culprit in obstructing the flow of electrical current. The dirt and grease can accumulate on the starter and the battery, and corrode the cable clamps and terminals of the battery.If this is the case, disconnect the battery and use a fine-grade sandpaper to clean the affected areas. It will remove the dirt, stain, and rust. If the corrosion seems pretty stubborn, apply a mixture of water and caustic soda. Be careful about not to damage any connections.SEE MORE:5 Things to Check for Car Hard Starting ProblemsHow to Diagnose an Engine that Doesn’t Start?Tap with a ToolIt’s another simple trick to the manual of how to start a car with a bad starter. If the starter is dead but the windshield wipers and headlights are working, the problem could be a stuck gear. The starter cannot function properly if that happens.Give the starter a tap about 4 to 5 times with a tool such as a hammer or a wrench. You have to carefully locate its position inside the car and distinguish it from other components. Besides, the taps should be gentle so that the part is not damaged.Tapping the starter with a hard tool might be effective.Sometimes, this method works even if the starter is actually bad. In that case, tapping will provide a temporary fix but the car could be dying anytime soon.Give the Car a Good ShakeIt’s another trick to release a stuck gear. However, you should do it only when you are a noob and don’t have the expertise to open the hood and locate the starter. Push down the vehicle’s handbrake lever while it is in top gear. It will rock the car and may loosen the jammed gear in the process.Ref: Find best deals of used cars from reliable Japanese sellers
How long does it take to repair a head gasket?
You don’t repair a head gasket, you replace it.Once I had a rally car - a bit of a ratty old junker if the truth be told - that had a 2.3 litre overhead cam engine. It was a bit like this, only this one is way nicer:Anyway I was heading off to do a rally on some Friday night. On the Thursday, the day before, I took it out for a blast around the lanes to shake down any last-minute faults, and blew the head gasket. It was too late to do anything about it that night, so next morning, I got up at the crack of dawn, stripped the engine down to the point of having the head off (it was OHC, so that involved also removing the cambox, timing belts, etc. plus the exhaust manifold, inlet manifold and carburettors) By then it was almost 9am, so I drove to the nearest big town - 25 miles away - to get a replacement head gasket set. 25 miles back, and by 10am had the head all cleaned and ready to be reassembled. Engine back together and running by 12pm, I then had to drive it 250 miles to where the rally started. It all went smoothly and I made it with plenty of time to spare.So the answer to your question, for me, on that occasion, for this car, was about 6 hours, including an hour to fetch the parts. Sometimes what you need, apart from the basic skills, which in my case don’t amount to all that much, is a great big incentive!As I recall, the rally ended in disaster, but that’s another story.
