ignition switch power ? stumped
 

im having some problems with my fc ive replaced the battery , ignition switch ,main relay , and almost all my fusses. my idiot lights will not come on or will the car click or crank ,all i have is hazards and head lights and this door beeper, i am getting 12.46v to the ignition switch but when i turn the key to start it goes away. i know it sounds like a bad ignition switch but i have tried 3 of them now and one was from a running car. what should i check next

Is the battery hooked up correctly. I only say this because I have installed the battery backwards before.

yes battery is new and correct and i have new termenels that i took the paint off also and i jumped the starter and it crank the motor over

Clutch switch? Neutral safety switch?

Clutch switch is bypassed

did you replace the fuses to rule them out or because they where blown?

I'd check your grounds and general power connections. I had this happen a couple times. Once when my battery terminals weren't connecting well and once when my starter wire (where it hooks into the starter) wasn't connecting well.

Replaced fussed to rule them out took starter off and cleaned connections to solinoid also clean driver strut tower ground I am getting power to my ignition switch but once I turn key to start the volts drop to zero

I would meter right after the switch. or take it off and measure the resistance thru the switch. Just to rule it out.

Thanks for the replys and help, I will check continuity tonight hopefully I can just clean the ignition contacts and will be back on the road soon since I have only drove the car twice since I bought it

ok so a new ignition switch and still no click no start no idiot lights or turn signals wtf.

OK
1. We can safely rule out the ignition switch.
2. Check all of you connections, and wires as well. I.E. Start with a good through look at the cables going from the battery. Positive isn't arcing or grounding out, and is in good solid working order, next do the same for the neg.
3. Double check all fuses and relays make sure they are in good working order
4. Look at your ignition switch make sure you did not cross any wires and it is hooked up correctly.
5. I should have put this first test the battery make sure it is good.
Start here and keep us posted.

battery is charged all fusses and main relay are new, ignition switch plugs are correct, battery cabel and grounds cleaned no arcing clutch switch bypassed

How are the connectors on the battery I had this issue with my 95 Bronco ans 78 Bronco and also the 84 RX7, Try wiggling them a little bit to see if you can get a better connection.
This I am assuming by the basis of when you get in the car all lights work normally, you go and turn the key and nothing if this is the wrong assumption let me know.

connections to battery are good. i have 12v going to the white/red wire on ignition switch when it is turned to off but once i turn to acc it goes down to .50v
