My 63 has been starting with no problem and I keep a trickle charge on it. Typically my Dakota Digital instrument registers 12v as soon as a turn the key to on. Went out this AM and noticed that the gauge was reading less that ~2-4v when I turned it on and then is just "clicked" when I tried to start it. Any ideas?

Battery posts have to be surgically clean,check grounds on motor,radiator support ground. Could be the battery just gave up the ghost.

Should have mentioned that both batteries read 12 volts.

Cable terminals are "surgically" clean. I will check on the Engine ground. Is it possible that my alternator is bad? It is regulated internally for voltage but would my gauge be reading that drop?

Take a load test on battery ,I just went through this on my Silverado. The battery read 12.5 volts but with a load it dropped down to 10, checked after load test 12.5 + volts.

My 64 will do the same thing every now and again. I've not replaced the wiring harness and the plastic clips get warm at the fuse block at the fire wall. I can wiggle mine just enough to make it crank right up. I took it all a part and cleaned up all the connections and reinstalled, it will do fine for weeks, months,days you never know. Thoes plastic clips get weak over time and don't keep it good and tight.

Put my glasses on and my Dakota Digital gauge only goes as low as 9v but I did notice it has a digital warning for low voltage and it was counting down ...8.5, 8.4, 8.3 etc. went into the sevens and turned the key off. Any clue as to why it would act this way?

voltage drop test works well. clamp together battery terminals suck. lots of grease on the battery terminals will keep the corrosion off after they are removed, surgicaly cleaned all over, and clamped on tight, then you grease it. i know it looks ugly but you cant wipe off corrosion. those felt washers dipped in oil work pretty good too. that spray on terminal protector crap is crap. it looks pretty but its crap. ground should go directly to block. big battery cables work better than 4 or 6 gauge skinny cables......as for the gauge, it sounds like a dead battery

Is the Drop Test something I have to take the batteries out and take them to an auto parts store.
The reading across them reads 26.6 volts (I have two batteries) and the date stamp on them is 11/17 and they are a premium (auto craft gold) battery. Terminals are fine.

are you sure your trickle charger was working and plugged into the wall? If it went bad or wasn't plugged it it might drain the batteries.

Yes. It is one of those that tell you exactly what its doing and its keeping up nicely. The batteries are mounted in the trunk and the PO told me there is a disconnect somewhere between there and the engine. Its got to be something simple.

hard for me to explain a voltage drop test. you need a volt meter. i would suggest a you tube search..............reread evrything. seems that you have a bad connection. find that cut off switch.

If you are going to keep your batteries in the trunk (since you have two, I imagine you would) I suggest contact Mark from M.A.D. Enterprises and ask him how his "New System" can help your car. He has a website with a bunch of research you can read as well. MadElectrical.com. Good dude and very knowledgeable about our cars.

How long have you had the car prior to these issues coming up? Have you made any changes recently?

How are your batteries connected together?
You mention they read 26.6 volts. If so then they are connected in series which is incorrect and will cause lots of problems including damage to gauges.
Connecting them in parallel does not increase voltage but increases cranking capacity.
Please verify how they connect and let us know.

I have only had the car for two weeks or so and am still learning it. It ran pretty sweet when it first got here. I fiddled with the electrics today and it finally started right up. Ran like crap but it started. Did a retune with the EFI and it seemed to run smoother. Go figure. We will see what tomorrow brings.

Is the car still using the original fuse box and wiring system? I'm sure there as been additions due to your EFI system but I'm curious if the electrical system has been updated with a more modern wiring system?

The car has been totally rewired with modern touches. That includes new fuse panel and something else that looks like a fuse panel (still researching that one)

OK, well that is good. Maybe you can find a brand name of the electrical system installed so you can download a wire diagram. You will never know when that might be useful in the future.

disconnect your ground battery cable connect a test light directly to the battery and the other end to the battery cable. Is the test light lit? If yes start pulling fuses one by one until the light goes out. Now you have narrowed it down to which circuit is the source of your problem. Be sure to close the door or disable your dome light so that it is not on.

Check the obvious first- that would be loose alternator belt. A loose belt can spin the alternator just enough to show everything working while the engine is running but, not fast enough to replenish the battery. Over a period of time the battery is drained. Deflection is one test and the other would be to turn the alternator pulley - does it turn the belt? If not, it is loose. The belt might not necessarily show any wear. You would be surprised how many alternators were sold due to loose belt.

The other obvious thing is to see if the battery connections are clean.

Put a meter across the battery with the engine not running. You should get between 12-12.5 volts. Turn on the headlights.....how far do the volts go down? If your battery is good then the volts should stay pretty close to the 12-12.5. If it is bad or discharged then it will go way down like 6-10 volts....When the engine is running you should get 13-14.5 volts across the battery indicating that the alternator is charging properly. Sounds to me like a bad battery or a bad trickle charger.....or you have a bad connection somewhere.

The 26 volts you are reading concerns me because they should be in parallel not series for most applications and should read 12 not 26.

Beautiful car. I had a '63 SS white Ragtop in blue/blue. Put in a 400/409 and replaced several trannys and a diff for my trouble!
Check to see if you have left under dash lights/glove compartment on or trunk lid open slightly. When you shut it off make sure brake lights are off which could mean a fault in the Alternator or brake light switch. I never needed a trickle charger but do now on my XLR. Check Starter ground if it has one and of course engine ground.

Nice choice on the cable size.

How did you do the Grounds?????

Some of the Street Rod people try using the frame for a ground conductor and it creates all kinds of problems.

I would suggest that you get a negative cable that has the crimped on battery connector, instead of the repair connector that you have on the left battery. Eventually, those connectors cause problems for a variety of reasons. I would only use one as a quick repair to get home, where I could fix the battery connection properly.

Never argue with an idiot. He'll drag you down to his level, then beat you with experience.

Parrlel batteries give you 12 volts but doubles the amp hrs for starting and anything that depends on the battery to run as the radio are wipers head lights.

So you doubled your run time if the car is shut off.
