First the fuel gauge started acting up, then the speedomoter quit an
the Brakes, ABS and TCS warning lights came on.
I cleaned up the battery terminals and topped up the battery wit
water (it was pretty dry) and the gas gauge now works fine but th other problem won't go away. It only happens after driving for a bit When the car is started it behaves fine for a while before the speed quits and the warning lights come on
I was afraid that the battery might have given up since it was so dr
but it is fine - 12.9V after a few days
Any ideas
