I just bought this C3 and she was running great with no problems. Then this morning I go to start her she is completely dead. I put it on a trickle charger all day and then tonight it was the same thing.

I noticed the battery has a quick disconnect so I disconnected the battery and charged it. When it was done I went to start it and same thing, nothing. No click, no slow turn, no dash lights, nothing.

Help!

 

Try turning on the lights. If you don’t get anything, remove the quick disconnect. Next I would use a volt meter to make sure the battery was putting out 12 bolts. Try a set of jumper cables or a emergency jumper battery starter to see if the lights come on.
Good Luck

 

then try jumper cable from battery neg to engine block. the main ground on the frame right below the battery dies.

 

Check and see if you have power at the starter.
then check adn see of you have power at the horn relay. Your electrical systen gets power from the starter lug though a wire up to the horn relay then into the fuse block. If the fusible link is blown or cracked your car will be completely dead...

If its the fusible link you can buy a new one and solder it in. You should investigate why it went bad but my guess would be heat and age. There is also fusible links up at the horn relay as well. You should invest in Dr Rebuilds Osoez wiring harness schematic and a color coded one from a vender like Willcox

let us know what you find

 

The battery had a dead cell. I bought a new Optima Res Top and put in a new ground wire. Works great now

 

Thats rare...good job

Welcome to the Corvette Forum! We are Glad you are here as THIS is THE place for Corvette Information!

This very day 29 years ago on July 19th 1991 I bought my 1968 C3 Big block convertible. Back then the 1968's were worth a lot less than the '69 and later Corvettes. Nobody really liked the weirdness' of the 1968 model Corvette. I bought my Corvette after it was Barn Stored and brought to a gas station. I paid a lot less and I got a Big Block L71 Corvette. Their loss. Today the 1968 C3 is finally making a great resurgence and their values are up in the range of the rest of the Chrome bumper C3's.

Just be sure to get proper insurance or the insurance company will screw you over really well. I have a Declared Value that they accepted but be very careful with old Corvettes. My car has out performed many 401 Plans in gained value and I get to take it out and play with it when I want to. I certainly would not buy a Corvette and expect it to grow more valuable. A very early L71 Convertible with 4 speed with its big block is a pretty good bet for an investment in a Corvette. I had a Buddy who bought a low mileage 1970 LT1 Convertible C3 and spent a lot of money as a drive-able specialty investment. I buy Corvettes to DRIVE them....

The 1968 Corvette has a Lot of "one year only parts" on it so use this Forum to get the help when you need it. Which model did you get? When you have a moment you might fill out your profile so we know what kind of Corvette and what mods it has.

I love my 1968 Corvette and get that "feeling" when I drive it. It is now wrapping up becoming a EFI corvette using a Holley Sniper Stealth.

Take some time and enjoy that Corvette you have!

P.S. Be sure to order an Assembly Manual and the Factory Service Manual. That will get you started and remember WE are here ready and willing to help!
