I was looking for a no current draw solution so the above comment regarding the 10 amp version caught my attention. How come that the 10amp version does not draw any power? I found the manual http://timers.shop/assets/documentation/..._Timer.pdf and I don't see anything that proves the above statement. I do assume that we are talking about this product https://www.amazon.com/dp/B01HNDOCKK/ref...VNYTBOTLXV&dchild=1&keywords=10a+relay+timer+control+module&qid=1602407863&sprefix=10A+timer%2Caps%2C311&sr=8-4 correct? Thanks

This is important as my car can sit for some weeks without being used. I'm not sure where I got that information from (too long ago now). It looks like that if you implement scenario 4 in the timer cook book "Time Off Delay Self latching circuit with zero current consumption during off state" you can get zero consumption. The downside is that you will require another relay.

This is important as my car can sit for some weeks without being used. Seems that the older version of the manual https://images-na.ssl-images-amazon.com/...mW9PRS.pdf has a separate section 12. 10 amp Timer 10 amp timer version offers extended power handling and also features separated power for timer control (Orange) and output circuits (Red). The following diagram shows how the 10 amp timer can be used instead of 5 amp timer. The power should be supplied to both Red and Orange wires. Separating power for timer circuit and timer output provides greater application flexibility. It allows for timer to be connected directly to power supply battery but control the timer function with lower power signal like car or motorcycle ignition wire. With ignition OFF the timer has zero stand-by current consumption which is great for battery powered applications. With ignition ON timer performs required timer function. The following configuration can be used to delay the power to motorcycle accessories after ignition is switched ON I am not sure if this is still the case since the new version of the manual has no section about this I found out that the wifi version http://timers.shop/assets/documentation/...r_Wifi.pdf will draw only 0.05 ma in low power mode so perhaps this is low enough to use. It is considerable more expensive though from the non wifi versions.

The circuit I made and the code I use have no current draw at all. I did post it on this forum

Just want to thank you for this tutorial, i was struggling to find a way to do this and this worked like a charm . Bellow is a picture of my implementation of it.

I have used this setup and it is working perfectly. Thank you.
I did have some trouble finding the STSP NC relay. Looking at the local auto parts stores, they just had 'NO' relays, not 'NC' relays. After rereading, the directions stated to use pin 87A. STSP relays do not have a 87a pin. STDP relays have the 87A pin and these are available at your local auto parts stores. I was fixated on STSP NC, but then after looking at these diagrams, I realized a STDP relay would work. If you connect to 87, it's 'NO' If you connect to 87a, it's 'NC' Hope this helps. Craig

Can I connect the blue wire which apperently is the trigger wire from the timer to one of my switched fuses instead of connecting it to my ignition directly. In other words can the blue trigger wire handle the 12volt power and use this as a trigger for starting the countdown?
