friends, my car's battery was dead, I started it by boosting, I was running FN by hitting it because the battery died, finally I installed a zero battery, but this time, my engine light turned on, while the rpm and temp gauges drop to zero, then suddenly it comes back to itself and sometimes when the ignition is turned on, the engine light does not come on, the starter does not work, the ignition is on. If I turn it off, it works when the engine light comes on all the time.

The car may have jumped to the cents due to constantly hitting it, bro. Have the vehicle's synthesis checked as soon as possible. In addition, have the vehicle's alternator and connector checked.
