Hope someone can give me direction. I am not sure where the long beep went after I turn on the ignition key initially on my throttle assembly. It used to be that when I turned the key to on, not start, I would get a long beep initially. Not sure exactly what that was for, but it always worked until recently? I also noticed that my gauge lights are not lighting up so I am guessing that this has something to do with the missing long beep. PLEASE Help.

Also, I need to mention that I noticed my gauge lights on my dash were not working either. Usually when I turned the key to the initial Run position my gauge lights would come on and I would get the long beep in my throttle control box. Could this be a fuse?

The beep in your throttle is activated by the oil alert module when it initially see's 12 volts during key up. If you blew the fuse, which is mounted along side the starter, your engine won't crank.

Engine still turns over, so fuse must be good, its just that I am not getting the initial warning horn long beep and my gauge lights are not coming on when I turn the key to the run position before starting. Have not had a chance to check the fuses under the dash yet, but I just want some opinions on what might be causing this before I lay on my back and try to squeeze under my dash which is an extremely tight spot.
