Thanks and I guess you are starting to believe Dave and I. In regards to the battery, they are soldered. If you decided to try it your self, you need to find rechargeable batteries, have them charged, which can be a challenge as the batteries must have soldering tabs. If the batteries leaked and damaged the board or there are bad solders, the batteries won't help. A new board with 1 year warranty is around $150. There is no way to delete the board like older BMWs. I tried once to do the batteries and was more of a pain. Swapping the board is very easy IMO.

Good luck

thank you for your reply.

i have a spare instrument i had 10 years ago. not sure if it can be used. i will open it to have a look. perhaps just swap the board that comes with the batteries. can a 10 year old batteries be still usable and able to be recharged?

thank you once again

Depending on the state of the batteries. If the the board is compatible, which it should be, the batteries should recharge but would they hold a charge being so old without a charge, I don't know. If you want to do this one time only, I suggest you have a new board.
