Started with the speedometer not working or flickering. Then replaced 12v battery. The 144v battery has beed disconnected a while. I found one ground wire loose but still something is wrong. The 12v battery has now run down! Anyone have any guesses, because I'm at a loss here.

Recharge your 12V battery in the meantime; Check terminal connections to the 12V battery that all are shiny. Use steel wool if req. to clean if oxidized. Careful of arcing.
Make sure good grounds to vehicle as you've mentioned. ..has the BCM been disconnected or just the IMA switch under the cover been turned off.?
To run without the ima system and still charge the battery : search "bcm disconnect" as keywords to see the two plugs that need be removed from the battery control module, hopefully that should bring up the recent thread.
Battery connections are very clean, BCM totally disconnected since last winter. Driving down the road sevens like something has come loose since speedometer would flicker once in a while and try to work. Other gauges were working. But when it flickered, the engine seemed to stutter. I'm to the point of replacing all the ground wires. Maybe one is broken and I can't see where it is.
Here's the link to the google docs pdf of location of the electrical components in the car.
There is an index at the start of the file with grounds listed at the back.
Here also is a link to wiring diagrams; hopefully the cluster will not be at fault.
Wondering if it could be VSS vehicle speed sensor related? Pic of VSS is in Fig 14 in electrical locations.
Have not been able to check the codes due to being out of town with my job. Going to jump on everything tomorrow. Thanks for the wiring info. Will post when and if I find something.
Here's codes linked as a google doc spreadsheet . nb.fig. 1 in locations also shows the right wheel speed sensor connection, looks readily accessible to check; it's located in the engine bay just below the hood-prop latch.
Cleaned all the grounds, charged the 12v battery. Have test driven serval times, checked all the fuses, speed sensors, replaced brake pads while in there, no speedometer and no fuel economy gauge. Tried to get it to flicker, it did once. When that happens the brake light and the 12v battery light flickers as well. By wriggling the parking brake lever the brake and the 12v battery light also flickers. I'm not applying the parking brake but when in the off position wriggling it side to side. Very strange. Taking a break and then going on the road to test the brake lever side to side to see if the lights come on.
Fishtrap:
Maybe include your location in the details of your profile.
You do have an emergency hand brake switch to activate the light so that could be the problem. (Interm, short or loose connection)

Disconnected the hand brake plug, no difference. Ran up and down the road wiggling the hand brake and the speedometer would flicker, don't touch the hand brake and the brake light and battery light stays on until I accelerate some and they go out, but still no speedometer. I'm pretty good at figuring things out but this is stumping me.
