push button start and relays

  Yo, soundinstaller.  Any ideas on that rs?  I think I would like to keep it in mind for a backup.

OK. Here is how I do it. Never seen a RS that has a timer defeat, so I will tell you how I get around it. I prefer the DEI piece (551T I think it is), but this config. should work with any starter unit. First, you need something that will give you a latched circuit. I believe you said that you wanted to use a mechanical on/off. That will do it. You will use that switch to send a constant ground to a pulse generator (dei# 452). You will use two outputs on this, one pulsed - output when ground is applied from your switch, and another pulsed - output when ground is removed. The "pulse when grounded" output will go to your rs activation wire, and the "pulse when ungrounded" output will go to the rs shutdown wire. In addition, the ground output from your switch will also trip an external relay cluster that will power your coil, and any accessory circuits that you might have. To be clear, you will only be using the rs unit to crank the car initially, and for tach monitoring. That's the basics. Let me know if you have other questions.
