After going through everything on the car I ponied up and bought a DC to dc converter used on fleabay. Hot swap and I have 13.5v at the battery and a reasonably balanced pack. I wonder if this pack has been replaced at some point.

I'm happy as a clam. Time to get the rear seat back in and take her for a beat.

Thanks S Keith. If you need anything let me know.

Once I get everything ready assembled and clean i may post pictures

 

Very nice!

A nice tidy summary to end it all would be perfect. This one had me baffled.

 

Well. The war is not over. The pack must not have turned out as well as I thought. 25 miles in the country at 55mph. Stopping hard and accerlating hard occassionally to clean the rust off the rotors and testing the Ima a respectively the Ima light came on.

P07af. Pack deterioration. Bah humbug. Right after I read assembled the back seat and washed it. Guess I counted my chickens before they hatched.

Getting on it hard dropped the SOC meter about 5 bars. It comes back up when you allow it to charge but in 25 miles of flat country road I saw the SOC meter cycle two full times.

Everything works as it should, even auto stop, and I averaged 42.4mpg in that time.

I really don't want to pull the back seat and check taps voltages but I need to. Blech.

Will report back in a bit...

'S Keith, do you happen to have the picture of the pinout for measuring the tap voltages? I can't find mine...

 

I have a pack delta of .13 voltages. 181v at the mains. 16.38 to 16.51 at taps.

This can't be the cause of my light.

I've attached a photo of the taps measurement from the service manual for my future reference.

 

Unfortunately, resting voltages don't tell all the story. What's likely happening is that the delta gets pretty wide under load/regen, and the car is registering deteriorated usable capacity.
