my brother took my SHO out last night and left one of the lights on all night. this morning, had to boost it up but the the rpm's weren't moving. everything else is fine, speedometer, temp gauge, fuel guage. looked at it and i see that the tachometer is stuck underneath this little black needle. is there a way i could fix it without having to do alot of work, for instance, removing the dash? its on a 91
