Snow storm coming tomorrow. Will do that in the weekend. 10 inches of snow expected and awaited by mother nature. This year not a lot of snow, if it keeps this trend we gonna have a drought here. Snow in the mountains are kind of mother nature recharging so we can have good spring and summer.

Thank you again.

 

Doing it on a morning you don't have to go to work is best. Take your time.

 

Ok the panel is removed...

how I measure that tap voltage?

https://drive.google.com/file/d/0B_6...ew?usp=sharing

do you see the red arrows that I drawed?

are those the poles I'm suppose to measure the tap voltage? I measure like a AA battery right?

I'm gonna test my multimeter in AA battery then use the same setting on the car just in case... I'm pretty much a newbie.

 

The terminals you marked have should have no voltage to them with the master off and the ignition off.

Check the 11 voltages here and record them to two decimal places each:

 

Is that in front of the car? next to the suspension?

do I leave the switch to off? or I have to switch to On

Do I need to put the key to acc ON?

 

Ho just notice it's next to Inverter. Is that bcm module?

 

No. It's the orange plug in your picture just to the left and below of the terminals you have marked.

Key off

Master switch off

It's the BCM

 

here's the result:

b6-b14 14.87v
b14-b5 15.05v
b5-b13 15.70v
b13-b4 15.38v
b4-b12 14.46v
b12-b11 14.52v

b7-b1 15.76v
b1-b8 14.41v
b8-b2 14.37v
b2-b9 14.97v
b9-b3 14.70v

what this is suppose to tell us?

 

The difference between those 11 voltages should be extremely small. Your minimum is 14.37V. Your maximum is 15.76. This is a difference of 1.39V. This confirms 100% that your pack has failed.

It appears that 9 of your subpacks are suffering from very high self-discharge. The two 15.7X subpacks are the only two that are likely functioning well.

I would not say that you've had a full cell failure as cell failures tend to be outliers. Yours are all over the place seemingly at random - actually, it's your two good sticks that are outliers.

Since you don't appear to have a full-on cell failure, I would put your success rate at > 50% with a Prolong reconditioning package. You will need to do the full process (3X charges/discharges) before you can expect results.

 

Still over 50%, should I try...? I know you can't answer for me but still tempted. it's 400$ vs 2300$ (prolong vs bumblebee) I know it's not the same. But if I can squeeze a little more life, it's worth a try...

what would you do? still want to ask...

beside having bad MPG, what is the danger to drive with a bad Pack?
