67' New Yorker - Large flash and then no power


I had been charging the battery on my 1967 Chrysler New Yorker when I got in to start it. I turned the key and there was a large flash (I couldn't tell from what direction), a pop in the speakers, and then a complete loss of power. No lights, nothing. The car had started several minutes earlier so I don't think it's the battery. I blew something, I just don't know what.

Disconnect the battery and look at every fuse! Also inspect your wiring harness, etc. YOu might have blown the main fuse bus and is a major fire hazard.

Charging a battery leads to clouds of hydrogen gas around the bat., which any spark can ignite. Lucky you didn't have your head under the hood!!!!!!!!

Forgive me for being ignorant, but where and what is the main fuse bus. I checked all the fuses and they look good. I briefly looked at the cables running from the battery yesterday, and I didn't see anything that looked unusual, but it's hard to tell because everthing is so filthy and old.

I think Bill's onto it. As a kid me and my mates would get old batterys and put them on charge in a box, we rigged a spark plug up in the box.the result was a loud bright flash that destroys the battery, sometimes not visable as it will warp the plates inside.

P.S Don't try charging the battery in the box trick.

as a,c said you probably shorted out the battery seen this where pos. becomes neg. try another battery disconnect yours if you intend to use jump cables for a test.

also if you dont have another batt. and use jump cable from another car leave that car off to not damage the alt. it also could be a bad ground let us know how u made out. if u use a jump just see if the interior light lights if it does change the batt. use a body ground for neg. cable pos straight to pos. with your batt totaly disconnected.
