It is advised to get a professional to inspect and repair the wiring to ensure the vehicle runs safely and efficiently.
Here are a few reasons why the wire from the battery spliced into the coil might be causing issues:
1.Continuous Power: Splicing the wire from the battery directly to the coil provides continuous power to the ignition system, even when the ignition is turned off. This can lead to overheating of the coil and premature failure.
2.Electrical Overloading: The coil is designed to receive power during specific intervals controlled by the ignition system. Bypassing this controlled power supply by splicing the wire directly from the battery can overload the electrical system, leading to damage to the coil and other electrical components.
3.Ignition Timing Issues: The spliced wire may disrupt the proper timing of the ignition system, affecting the engine's performance and causing rough idling, stalling, or difficulty starting.
4.Risk of Electrical Damage: Incorrect splicing or poor electrical connections can lead to short circuits, fires, or other electrical hazards, potentially causing severe damage to the vehicle's electrical system.
It's crucial to have the vehicle inspected by a qualified mechanic or auto electrician who can diagnose the exact issue, repair the wiring properly, and ensure the vehicle's safety and optimal performance.
