GD Toomes DD PTE6262 07 Hawkeye. What a long, long adventure this has been.

multimeter say .5V and draining, I think its foobard.

Yep it sure does sound like it. Hey when you get a chance and since your a sponsor go to the garage at the top of the forum and create a garage. New feature. Also post to your user name.

Once the car is started it should remain running even if you totally disconnect the battery. The alternator should keep things going. If it is stalling when you disconnect the jumper then I believe there is an electrical problem somewhere in the alternator circuit. This could be complicated by a bad battery at the same time.

In any car electrical system it is the job of the battery to start the car and once started, the alternator takes over to run the car and all of its systems and to charge the battery. The alternator should be putting out about 13.5 volts at idle

I would start it again with the jumper and remove the battery and then the jumper and see if the car remains running. If it stalls, then the alternator is not putting out. If it remains running then the battery is probably bad and pulling down the rest of the electrical system when its connected.

Just my thoughts.

Here's the latest anyways...The second I take the negative away to car dies. The battery even after running for 20 minutes puts out like .5 volts. My next guess is I fried the wire from the alternator to my fuse box? If I get a new battery, sure it will start up...but how long is the battery going to last. My buddy Mikey thinks it's the battery at all costs given the symptoms.

Mike Schear - If it's .5v with the car off, the battery is toast, especially if it won't take a charge from the alternator. When the alternator is running, it should show ~14v, with the alternator off, it should be ~12v. Sounds like the alternator is putting out a charge, but the battery has a cracked cell.

Here is something positive!! This is how the car is currently sitting and some random pics of the engine bay, since I finally started using the Canon EOS 40D I was given:

I has a garage.

Yeah there is no doubt that your battery is kaput. but if the alternator can't keep your car running with it disconnected then that warrants some investigation as well.

hate this car.

So here we go with a brand new Optima Yellow Top.

What I know:

1. New battery
2. Alternator tested out.
3. Battery was 84% when I started the car
4. I know there is still a problem

What I can't figure out:

• Where the problem exists.
• Why the alternator isn't charging the battery?
• Why I still own this car.

Basically I know there is still a problem. After a 25 mile drip/RIP the battery registered 11.5V instead of 12V. I have to only assume that the 12v from the alternator is fried somehow or I just simply have a shitty ground somewhere?

One big question is...if I get a ground kit - will that be a lazy way to potentially fix the problem so that I can enjoy the car until I have the harness tested or something?:rofl:

 

[toomes]

You know what. F**k it. I am grounding everything in the car.

The only risk I see in doing that is you may not fix it at all and you would have done that for nothing.

In the mean time I'm going to take a hard look at the wiring diagrams for the charging system to see if I can isolate anything for you.

 

[HolyCrapItsFast]

Let me ask you a stupid question. Did you remember to connect the green 2 wire plug to the alternator? :lol:

You should see battery voltage at the big post connector on the alternator. You should also see battery voltage at the Blue/Red wire coming out of the green connector on the alternator.

The fuse responsible for the alternator is Fuse No. 3 in the main fuse box in the engine compartment. Check that fuse.

 

[toomes]

Yes the green plug is installed along with the 10mm nut wire!!! :Rofl: Guess how hard it is for me to measure voltage on my alternator? It's upside down now

Thank you for checking on the fuses, I will literally check on this first thing in the morning. I thought there was a main fuse that might have blown, but its a 120A and it does not appear to be smoked.

 

[HolyCrapItsFast]

The fuse I was suggesting is a smaller one that supplies the green connector...

and here is the diagram is referenced just for shitz and giggles...

 

[toomes]

I hope to god the fuse is just blown. I am so tired of one thing after another with this car after a year of building.

 

[HolyCrapItsFast]

I feel you pain

 

[toomes]

Fuses were all good in the main fuse box from what I could tell. The battery was almost entirely dead this morning...that has to be a serious drain.

 

[HolyCrapItsFast]

heck yeah. I'm all out of suggestions.

 

[IGOTASTi]

What is all in your car that pulls power?

 

[toomes]

I disconnected my 2 Prosport gauges and my AEM wideband. The only thing that has changed is the injector clips and the fan wiring. I guess I need to see which color on the fan was ground since I have a universal now and it only takes 2 of the 4 connections. Maybe that is it?

 

[IGOTASTi]

Sure could be. Something is pulling power.
