Need some advice/confirmation on what I want to do with my Cobra Electrical system. Pls refer to the attached electrical diagram (in particular, the lower right hand corner).
Background: I will not have a keyed start option. I’ll have a on/off switch for ACC and Ignition On and a start button. For security, I’ll have a remote battery switch that’s activated electronically when you supply a ground to it (i.e., no manual key to turn on). I will also install a Viper 5901 security system.
Plan: I want to add a simple standard relay switch to the remote battery switch to supply the ground to it to supply power to the car. I want to activate the relay with a negative input from the Viper security system. When the Viper is disarmed, it can provide a Aux/trunk 200mA negative output. I’d connect this output to the relay. This in turn would provide a higher amp negative output to the battery switch. The battery switch is the Painless # 30204 (
http://www.summitracing.com/parts/PRF-30204/ ). It came with a toggle switch to supply the ground… but obviously, this is not a secure option… therefore why I added the relay and connection to my security system. Not knowing the amp draw on the battery switch negative/ground activation, I’m playing it safe by adding the relay for the ground.
So, my question to those that understand electronics…. Do you believe the 200mA negative output from the security system will work OK to supply the ground to the reply switch to activate it and therefore offer a good ground to the battery switch to cause it to active?
If you need any further clarification…. Pls ask.
Thanks to all in advance…. Mark
