I'm trying to track what appears to be an electrical problem with my 1994 C280. When you hook up the battery, the entire dashboard lights up without the key in. When I try to turn the ignition with the key in it, nothing changes. The car doesn't start either. I replaced the ignition switch which didn't help, disconnected the alarm module assuming that it could be thinking it should be immobolized. I only have the keys no key fob so I cannot try and arm or disarm the car that way.

I checked the fuses under the hood as well as in the trunk and they all in working order. I began pulling relays hoping to find the one which controls the dashboard but I haven't found it.

I saw a post in the DIY Articles section talking about the alarm disablement and it would require placing a jumper on the relay. The unfortunate part, is the article was for a 93 and they moved the alarm module to the trunk in 94 and I'm not sure where the relay for the alarm was relocated to.

Any suggestions or help if you've seen this before would be greatly appreciated. If you need additional details let me know.

Thanks!
Brian
