Default Car will not start

1969 corvette L46 with AC

All I get when I turn the key is a soft metallic sound (relay?)

I am getting no voltage across the neutral safety switch.. so obviously no voltage to the starter.

Also I get no buzz from the horn relay.

Where do I go from here?

Thanks for your help.

What is your battery voltage? should be around 12.5 volts, no load.

If ok, start checking your fuses.
good luck

I agree with John485. Sounds like battery to me.

Battery measures over 13V .. no load.

Can someone provide me with a starting circuit diagram?

My hood is off. Is there a theft deterrent relay I should be concerned with?

Any other ideas as far as trouble shooting.. I'm lost right now.

Sounds dumb but what is the voltage on your battery?

Over 13V unloaded... I'm not sure if that tells me I have a good battery.

Put it in nuetral and try again.

You need to start at the furthest point away from the battery with the key on and keep checking power til you find it. Your ignition switch could be a problem too

With the key in the start mode (or accessory mode)? sorry .. I'm a stupid mechanical guy.

You checked your battery voltage at the battery, but did you check your battery cable connection? Check that voltage at your alternator or starter to see if the battery cable is making a good connection. Often times with a bad battery connection, you will see 12+ volts in your accessories and at your starter until you turn the key. Then it goes "click" and dies. Did it just start doing this?

As for the neutral safety switch, you can jumper that to eliminate it. Sounds like a bad battery cable or connection to me.

OK.. Thanks.. I will jump the nuetral safety switch.. and yes I do just get a muted metallic click when I turn the key to start.. I'll check my battery connections.

Since I am by myself it is hard to check voltages when the key is in the start position ...

It could very easily be the solenoid itself. I'm not sure what you mean by no buzzing from the horn relay

I guess I'm referring to the key buzzer ... not getting that noise.. I was thinking it came out of the horn relay for some strange reason.

Pull on the headlights and turn the key to start. If the lights start out bright and go dim with key start actuated, its either a bad battery or a short in the starter...badly worn brushes?

Just to check connections, hook the positive meter lead to the starter lead and the negative to the frame of engine (not across the battery) and turn the key to start. How low does the voltage drop when you do that?

with the headlights on and you turn the key do the headlights dim or go completely out. If they do its usually a grounding issue
