Race Car Starter Solenoid Wiring. The idea is to eliminate the voltage dropping effects of all the start circuit connections through the firewall bulkhead ignition switch neutral start position and unknown lengths of wires connecting them. Single starter relay car starter wiring diagram when large power starter is equipped in order to reduce intensity of the current that passes through the ignition switch and avoid ablation of the switch the start relay is often used to control the heavy current of the starter solenoid switch and the ignition switch start position is used to control the low current of the relay coil.
Many times it s due to the design of the start solenoid and the available power to it. When either the rear switch or the drivers kill switch the power is broken to the ign car etc and the altenator feed is going direct to the battery so it cannot backfeed the ignition. Kill switch interrupts ground circuit.
Transients can be managed with the use of diodes across the coils as well as proper wiring techniques.
