Need help locating home for this capacitor
I have a question concerning a .47 mfd capacitor. I just installed a new carpet in my 82 vette and knocked loose this capacitor. I do not know where it goes. I was putting on the driver's side kick plate when it fell. So I assume it was knocked loose from the fuse box. It is a yellow/gold capacitor with two contacts. The contacts are angled with one horizontal and the other vertical. The car will not start. The battery is fully charged and all accessories work including the power seat but nothing happens when I turn over the ignition. Does anyone have any information that may help?
Thanks

Looking at the pic, the capacitor is there to repress current surges created by the blinker to keep the blinker contacts from arcing (and welding themselves together or apart).
This should have nothing to do with your start problem. Perhaps something else also got knocked loose.

The capacitor is there to stop the "popping" sound in the radio when the flashers are activated. They're installed on switches, flashers and motors to keep noise out of the radio. Most noticeable on the AM band.

Perfect. I thought is was a suppressor but had no Idea where it went. I removed the signal flasher and pluged it in the same holes. Now all I need to do is find out what is preventing it from turning over.

I suspect you are correct. I had already checked the fuse for the crank. I will have to try all the fuses. Nothing else looks out of place. All the electrical appears to work fine. When I turn the key nothing happens except the seatbelt warning and breaklight go on.
thanks for your help.

The starter does not engage. Nothing happens. I will systematically remove the likely fuses but it is hard as hell to get them in and out. Are there any other likely suspects. I checked the connections at the battery and all looks good.

May also be a fusible link down at the starter. Check them and if one is fried or stretches it's bad.

Both fusible links are looking OK. I did try the shifter position first thing because that is exactly the way it is acting, as if it were not in park. It is and I tried it while moving the shifter just in case.

Test the power wire to the solonoid from the harness with someone turning the key to make sure you're getting power to the solonoid when the key it activated.
Maybe try jumping a power wire from the cable from the battery to the POS on the solonoid. See if you can get the starter to turn with direct 12V. That will rule out the starter or solonoid.

Thanks to all of you for your help. The problem was a bad battery. I had tried starting the car with the battery charger set at 75 amps start mode but nothing happened. I swappped the battery and all is fine.
Thanks again.
Thanks again.
