Hey guys I haven't been on here In a while because my trucks body is being worked on. When I parked it 6 months ago it would start up and run like a champ. I had taken the ignition lock cylinder out to paint. Well today I went to start it up and it wouldn't do anything not even click. Battery is good I tested it. I could jump the solenoid and it would crack. Well after using a test light I found out I have no power to the little terminal next to the batt side lug on the solenoid coming from the battery. I was testing it with the ignition on. So I decided to jump from the batt side of the solenoid to the small terminal next to it. I also ran a jumper wire to the coil to give it power. Once I jumped the ignition side small terminal on the solenoid the solenoid would jump over to the starter terminal and it would start and run good as long as I kept power to the coil. This is a brand new solenoid I just put on cause the old one was doing the same thing. My question is what is the schematic for the solenoid doesn't it get it's power straight from the battery and when you turn the ignition on it sends power to the little terminal next to it. Am I getting this wrong am I missing a wire somewhere? I am confused cause I have not touched anything on the engine since it ran last and it would start easy. Any help would be appreciated. Also I could use a drawing of the route from the battery to the ignition. Sorry for the long post.

Does it have a neutral safety switch that could be the issue

It's a manual but it has tryed to start before when in gear. Or are you talking about something else?

Power only goes to the small terminal on the solenoid when the key is in the START position, there is no power going to it in the ON position. Have someone hold the key in the START position while you check to see if power is coming through the wire that goes to the small terminal.

There are two small terminals I know it jumps across the two terminals when you start but are you saying the terminal closest to the battery side of the silinod only has power to it when you turn it to start as well? I am pretty sure it does not cause we had to run a jumper wire from the battery side to that terminal will turning the key to start to get it to crank. Does that small terminal on the battery side receive power from the ignition or is it vice versa?

"There are two small terminals I know it jumps across the two terminals when you start but are you saying the terminal closest to the battery side of the silinod only has power to it when you turn it to start as well?"
Yes.The small terminal gets power from the ignition switch in the Start position, thats what activates the solenoid to engage and send power to the starter and also sends power out of the other small terminal and goes to the coil. In the START position the only things that get power are the starter and ignition.. If you don't have power coming out of the small wire going to the solenoid nothing happens...

I figared it out. The ampere meter was disconnected so once I connected that it completed the circuit.

AAAAH! a minor technicality, complete circuits work much better, glad it was a simple fix and you found it.

A note on Ammeters: In the event you should convert to an Alternator, you need to remove the Ammeter. Usually the meter is not rated high enough for the output of an Alternator.. If you want a guage, it's recommended to convert to a volt meter and it's also safer.

With a generator does it charge when at an idle or does the rpm have to be higher to produce?

Has your idle dropped? Even a 50 rpm drop may be enough to start the light glowing. Put a quality gauge on the battery and check at idle to see if you really need to worry. My guess is that your idle decreases when you get up to temp.
