I have a 2001 Odyssey with problems. I found that if the car sits for 2-3 days without being driven, the battery is dead. the battery checked out okay (it's fairly new) and the alternator is pushing 14.? volts when running. I don't know if this may be related but I noticed that while driving several dash "idiot" lights come on the go off. The frequency is random and the duration varies as well. Bumps in the road have no effect. The lights that come on seem to be TCS, Brake, Oil (I believe), Seat Belt, and Door open indicators (all 5). Could I have a short/bad rely in a certain circuit? Also, odometer light doesn't work. Any ideas before I take it to the dealer and have them chase the problem? I don't know if I have that much money
Any suggestions would be greatly appreciated.
