Unhappy Battery putting a damper on my cruising . . .

Have a 69 350. Relatively new battery. Tests good. It's now died on me 6 times in the last 4 months. OK for a week or so, then won't bump the starter. Checked the (new) alternator. I'm not finding any obvious shorts (doesn't mean there aren't any). Had a new radio installed about 4 months ago. Noticed the other day that the radio flashes each time I use the turn signal, but one turn signal doesn't work on the dash. Hmmm. What do you think?

Thanks all.

Sounds like a Parasitic drain along with other issues, but first thing is check ALL grounds..

Sorry you are having problems. I too have a '69 350 which was my Dad's. I had a similar problem. It sounds like you may have a parasitic battery drain. If I recall the technique for finding the cause, it requires connecting a multi-meter between ground on the body of the car and the negative battery cable removed from the car. With everything turned off and the door closed so the interior light does not draw power, carefully remove each fuse to check for which circuit is drawing power. That will tell where you need to focus.

I think you need to buy a decent volt/ohmmeter also capable of measuring up to maybe 10 amps of current then read the instructions, watch youtube video's or find someone that can show you in real life how it works and THEN you can use it to find your issue(s).

Looking to see what is happening just by using your eyes is like asking how much water pressure is in you water lines at your house by just looking at the pipes or opening a faucet.

You just need the right tools and then a lot better help can be given ro answer your questions.
