You can measure the resistance of the injector. If the resistance is around 6-9Ω, it is generally normal.
The voltage is usually the generator voltage, which is about 14v.
Purely made by hand, I hope you will adopt it, thank you. If you have a problem with your car, ask the car guru. Professional technicians from 4S stores can solve the problem in 10 minutes.
1. First, pull the main wheel shaft of the generator outward to facilitate the subsequent winding of the belt.
