Thank you so much for all the help. Will a 1n4007 diode suffice?
Yes but should be higher amps.Anytime.
How many amps should i get?
Could I use like 50v 4700uF?
Yes you can.
How abt amps of the diode? 20 amps?
No, it's going to be used as a flyback diode. A 2-amp 1n4007 will work.
Would a 6amp 1000w diode be ok? I have this at home already
Will function.
Good day. Where should i place the other diode? Is it through from the relay to the compressor? Or from the thermo switch to the ac relay?
@Hassan1991 Thank you so much for the help. It is fixed already. Added capacitor to the acc wire of radio. Should it be connected to b+ instead?. 1n4007 from ac switch to thermo switch. 6a10 diode from thermo switch to ac relay. Thank so much. Really appreciate it.
Glad to know. Anytime.Yes, connect to B+.Also flyback diode should be installed between the coils pins of relay.
@Hassan1991 thank you so much for all the help! Would you know if ecu aignal to radiator fna send negative or positive? Thank you.
ECU provides ground to high-current devices.
Thank you ao much. It is indeed ground after checking diagram. Thank you for the confirmation.
