Help.Need Help With Wiring.Please

Here is what i have,I have a two position on off switch and a push button starter switch.the problem i have been have is that when i turn the on/off switch off the car keeps running,This is the way it is wired.Main power cable comes from battery to the starter,I have a wire coming from the starter to one side of the on/off switch.the other side of the on/off switch is the coil wire,and the power for the push button switch that runs back to the starter,and a acc. wire that powers my all the cars accessories.
I did some testing and found that if i discounted the accessory wire the car will work right.So i found the problem.the acc wire is back feeding my coil.
How do i fix it.where should i wire the acc wire so that when i turn the car on it will power up my accessories and not back feed my coil when it is turned off.Do i need any type of relay.If so where will it go and how do i wire it in.any help is wanted.

From the discription it sounds as if the alt is keeping the car running (powering the coil) when it is keyed off......anyone else?

I think your missing something. If you have main power coming in to the key, and then two wires coming out (on to the accessories and one to the push button start), then once you turn the key all things should stop. You must have another wire feeding the accesories outside of the key. Or you could have a bad key switch....can you start via the button with the key off?

ok guys,i did some testing today and found that what is happening is that my alt is backfeeding power.it is doing it at the d+ termanal.the idot light.so how is that termanal to be hooked up.i dont have a idot light.do i have to have one.I thought that i could just run a wire to that termanal from the acc switch and it would work.i must be wrong.do i have to have this wire,or will it cause my alt not to charge.

if you want the altenator to work you have to have the idiot light. It supplies for lack of a better term a signal or ground path via the light bulb to the voltage regulator in the alternator. The idiot light serves several purposes, for example it is nice to know that you have tossed a fan belt before the engine is toast...a bright idiot light at speed is usually just that.....

explain to me how an idiot light works and how i would install one.my gauge setup is not the standard setup.i am using the older cmc style gauges.6 in all.so it doesnt have an idiot light.is the light anything special.is it just a standard dash light with a negative and a postive,if so what is the right way to wire it up.thanks for your help.

Blake:

An alternator "idiot" light is, as mentioned above, used to provide a reference voltage for the regulator part of your alternator.

It is easy to wire up: Use a standard, 12 Volt dash light (from Autozone or where-ever, or use one that you already have there). One wire from the light goes to either your 12 Volt accessory circuit, or to the "Ignition On" lead from your key switch. Either way, that wire should have 12 Volts only when the key is "on".

The other wire from that light goes directly to the "D+" lead on top of your alternator (it is usually a smaller connection - not the big wire going to the starter or battery, but a smaller lead with a 1/4" slip connection on it. That connection on the alternator should be labeled "D+".

Notice that there is no "ground" wire to the dash light, just one going to ignition "on" and the other (you can call if "ground" if you wish) right to the D+ lead on the alternator.

Wiring it this way will allow the regulator part of the alternator to "see" what voltage the battery is and charge it as it needs it.

thanks gordan,i got it now.any advice on my other question about a hard clutch.
