Re: 2002 Honda CRV Battery keeps dieing over night
First you need to make 100% sure it isnt the battery .when you park it for the night take your battery cables off and leave them off until the next day.when you go to start it put them back on and if it starts up then its probably not a battery issue.(some batteries get weak and will not hold a charge overnight). if it starts then its probably a short in your wireing.also when you put the cables back on listen for a crackling poping sounds as you putting the cables back on the battery.a good indicator thats there a short in your system.i hope this helps thanks jeff

Check to see if alternator is charging. Battery light is an indicator that your alternator is not charging. Start engine use multimeter at battery 20 v dc or if autorange meter just dc. engine at idle the battery should read 14 - 14.5 volts. if not replace alternator.
A red battery symbol on your dash indicates that your charging system detected a failure. Your car might be running and working fine but its probably because your battery is in excellent condition and you are running everything from your battery. Unfortunately, your battery will deplete and cause your car to die even while driving so be very careful and have your local shop check your vehicle for a bad alternator or similar criteria. Try not to drive your vehicle at night or with the A/C on until the problem is corrected.
Well I suspect that you may have developed a problem in what's called the Multiplex unit. It's an integral part of the fuse box in Honda CR-V's. It's possible that the cargo trailer caused the problem by causing too much current to be drawn thru the system, I have a similar problem with my 2002 Honda CR-V and have been told I need to replace the multiplex unit and they are quite expensive. You may have to bite the bullet and have it checked by your nearest Honda Dealer.
I just posted my experience in another place on this site but on my 1992 PA the accessories relay stuck closed. This relay is the one that allows you to listen to the radio etc and keep things on until you open the door then all shuts off. When it is stuck closed accessories keep running until your battery drains dead. The relay was replaced and all worked great.
The wiper phenomenon you described is normal. It's a really cool feature. The car knows that you're moving so the wipers adjust to your speed.
The headlights and radio light problems you described is probably a bad battery. I didn't know about it either until I took my 07 CRV for it's 15k mile maintenance and they tested the battery. They said the battery was defective and wasn't putting out enough power so they gave me a new battery. Since it was under warranty, it didn't cost me anything.
