On the fifth day of my self-driving tour, I arrived at Sinopec gas station in Muyu Town, Shennongjia Forest area at more than 4 p.m., and I couldn’t start it after refueling.At first, I thought it was the battery problem, so I called Ping an free electricity rescue. He brought a portable battery with a lack of electricity. 12.3V. I said that this would definitely not start. Later, I turned to the owner of the small supermarket next to the gas station and used his van to pick up electricity. I couldn’t start it either. I judged that the starter was broken, because the rescuer had a computer and no fault code, and called Ping an free again. Trailer rescue. Because the person who connected the electricity was the owner and repairman of the auto repair shop not far away. After it was removed, the two positive electrodes were completely polished. He said that the man who sold the battery had a carbon brush to see if he could repair it, because the starter had to be sent from Yichang. It will take at least a day. I checked the starter 550-650 of “Heart” and “Mercedes-Benz House” Bosch. In order to be in a hurry, I still hope to have it repaired on the same day. The small owner of the auto repair shop and I drove the dismantled starter in a minivan to the battery shop not far away. He said that the repair time was at least half an hour. Let me and the auto repair shop repair first. When I said that the auto repair shop was also waiting, I stayed and found the carbon brush, the same size, that is, the line was a little longer. First, gasoline cleaned the toner. He was careless. I used a discarded multimeter needle to remove a lot of carbon mud. He rubbed a lot of toner and old butter with the back of his gloves. He didn’t have a cloth head. When he tried to install the carbon brush, he installed the sealing rubber on the new carbon brush, which was different from the original one and was missing a lot from the original factory. He said to wind it with tape, but I disagreed. I insisted on using the sealing rubber part of the original factory, and he said that it could not be dismantled. I straightened the bends of the two copper sheets below, cut off the remaining copper braided wire of the carbon brush, and pulled it out with sharp-nosed pliers. He also said that the new carbon brush could not fit into the rubber pad. I asked him to cut the copper braided tape and the installation copper gasket. Anyway, the domestic copper braided tape is too long and needs to be cut short. Then the cut place is soldered with solder wire, and the thin copper wire is not scattered, and it enters as soon as it is worn through the hole in the rubber piece. Then he said that if you install the copper gasket, you should not weld it again. I also agreed to use the copper braided belt directly, using the copper joint cut from the original factory as the gasket. The two braided bands were twisted two times, and the middle seams at the ends were sheathed on the screw. I used the original joint because I felt that the original copper joint was much harder, and I didn’t want him to look for the gasket any more. He didn’t even have butter. I bought a can of low-end hard butter. Instead of the regular blue butter, I didn’t care, didn’t say anything, just wanted to install it quickly. Try the battery, you can start, pay 150, take me to the auto repair shop. When he arrived at the auto repair shop, the boss was repairing his charger to recharge the battery. It took him about half an hour to install the three screws. It took 20 minutes to install the three screws. The boss asked for 300 yuan, refused to be less, I paid to run as soon as possible, a little over 09:00, but also finally repaired, the replacement of carbon brush 150 is not much, the attitude is also good, the small owner of the auto repair shop is a little too much, forget it, away from home. As soon as the car was towed to the store, it was not dismantled immediately, but it was first used to change the oil for a hatchback Chevy. The oil release screw was damaged, and it took almost an hour to look for screws and taps. During the time of taking electricity and towing the car, his two apprentices did not change the oil for the car, saying that it was a car repair shop. It looked not small. The two lifts were completely level on the floor. However, it was finally done on the same day, which did not affect the next day’s itinerary.
