i repair these things every day and the FIRST thing you do is raise the rear wheels, you never know who else is been working/messing with it. when you have one run over you or run though the wall in the shop you will see the point in this.

OK sorry I didn't see this thread sooner... Diagnosing an OBC is simple. First, determine what color it is.. Look at the front of the computer, the side facing toward the front of the car, not the side with the 6 pin pigtail coming out of it.. Is it a cream colored OBC? or is it a 2006+ OBC with a grey plastic casing and a pink tag? Both OBCs will turn the charger on within 2-10 seconds. The cream colored OBC will turn the charger off again in another 2-10 seconds, then back on and attempt to finish the charge cycle. The grey computer will not turn the charger off again until a few minutes into the charge cycle (depending on which version, most grey DS computers are V2.06, you'll find it on the pink tag) In either case, no matter what computer you have, it's absolutely crucial to make sure that the charger does NOT turn on IMMEDIATELY when the plug is inserted into the car. That's a sure sign that the computer is stuck in the on position and will NEVER turn the charger off. OBC is definitely bad if this is the case. The most common problem is battery voltage... Low battery voltage will keep a charger from turning off. Here's what you do. Plug the charger in, make sure it does exactly what I stated above... Wait until the ammeter on the charger is on 5 or below, and check the battery voltage across the entire pack with a digital voltmeter. If it's anything below 58.3 volts it will NOT turn the charger off. If this is the case.. check the On-Charge voltage of every battery in the pack, and see which one is causing the problem. Let me know. Hope this helps.
