Hi

Does anybody know of a wire I can splice into that has 12v when the ignition is turned to the accessory 1 position, ie when the clock illuminates up, and keeps the 12v even whilst the engine cranks over. Everything I have found so far does not keep 12v whilst the engine cranks over.

 

Thanks

Colin

I would have thought that when the engine cranks over, 99% of battery power is used in actually turning the engine.

 

That would give the impression that a 12v live circuit (eg the clock) is not live during cranking, when in fact it is. You are probably just experiencing a power drain from all other circuits when you turn the starter.

you could use pin 109 of the ECU (white wire).

It holds 12V when cranking and holds power for about 5 seconds after you turn the ignition off.

 

ideal for (boost/traction/fuel)controllers

 

don't use it to feed things that need a lot of power.

Thanks Lymon. That will be good to know for the future, as I don't need it for my gauges anymore, as I have been in contact with Prosport who have confirmed that they are supposed to turn off when you crank the engine. So I actually have wired them ok already, which is surprising for me!

 

Thanks again

Colin
