No clicking sound what key turned to start

[mwillmon]

Hey all, need some help here. I started my ‘75 to warm it up. Turned it off then when I was ready to go, went to turn it on again, nothing. No click. Battery is fine as lights will turn on. I replaced the ignition switch and solenoid. Still nothing. What else could it be? Thank you!

Put it in neutral. Get jumper cables and hook one to neg battery and one to positive, .The positive touch the pole on the starter. If it turns over it is not the starter. Make sure that when you try to start the solenoid is getting 12 volts .If not it is the key switch. Make sure that when you try to start 12 volts is going to the starter. If not 12 volts going to starter then it is the solenoid. It can only be three things if the engine will not turn over. 12 volts to the switch. 12 volts to the solenoid. or 12 volts to the starter.

Most likely it is a bad battery cable. Check the connections at both ends. The negative cable connection at the engine block is a common issue. Sometimes the cables themselves are broken inside the insulation.

Whatever you do, don’t throw away the old parts!
If they weren’t bad to begin with, they may last longer than the new ones and be handy to have a spares.

Do you have an automatic transmission? You might have a problem with your neutral safety switch.

And don't SOME manuals have a neutral safety switch also?

I have WAY too much experience in NSS "findings." Too many times, harnesses have been pulled looking for problems before finding....

Some vehicles do, but not early Broncos.
Often called a “clutch interlock switch”, or “clutch safety switch” along with probably a couple of other names as well.
Toyota got it right when they had a clutch interlock switch, but a pushbutton override on the dash so you could still crank the engine with the clutch out.

i ran into a similar problem .I found that the negative cable was a dirty connection where it connects to the block. cleaned and tightened ,fixed the problem

You all on here are amazing. It was the Neutral Safety Switch missing a bolt, creating it to be a little out of alignment. Realigned it (with the help of another post on this forum) and started right up. Thanks all!

Great to hear! And thanks for coming back around to let us know.

It just shows too, that a lot of problems that we try to diagnose remotely, can only be found by the person crawling around the vehicle.
