During car starts, the starter motor draws large amount of current.. Sir how can we protect the audio system from getting damage..

[@HaseebElectronics]

actually if the wiring is perfect, then all the car audio systems are controlled from the "REMOTE" signal. it comes from ignition switch and it is disconnected during car start-up. (this signal is disconnected during starting time) after startup this signal is routed again to turn on car audio system if this signal is not routed properly, it must be inspected and if there is some issue in this signal, then some manual solution may be incorporated

[@rolanpillo4254]

@@HaseebElectronics when you start the car while the audio player is on, it will almost die.. can a diode be used prevent the current draw? Any suggestion sir. Thanks for your prompt reply.

What value should you get on the VCC voltage

[@HaseebElectronics]

in TL494 it is 10 to 40 volt. normally it is 12 to 24 volt
