02 400ex electrical problem......

[CELICAMT]

I have an 02 400ex and for the most part now with the key on engine off nothing will work, headlights neatral light starter ect. it bump starts just fine but you can tell the lights are not running off the battery there running off of the alternator. if anyone has ever seen this before i would love some help or even where i can look at a wiring diagram. any help would be appriciated. thanks!

Check the fuse ( located to the left side of the battery)

replace it with another 15a fuse

if it pops the fuse when u turn the key on you have a short

Check the battery terminals, mainly the ground. Make sure they're not coroded, then follow the ground to the frame and check the cable there too. Usually 12 volt electrical problems go back to the ground as the problem. Hope this helps, Matt
