99 GMC Suburban -- While driving engine cut off, no power. Tried to jump but wouldn't. There is a ticking noise without the key in the ignition. Any ideas?
Does it tick then a bit later tick again? If so that's most likely an automatic circuit breaker that you hear. If you have a short in the wiring the circuit breaker kicks out (tick) and shuts that circuit down, after a minute or so the circuit breaker cools enough to reset itself (tick again). That would explain the truck shuting down. The circuit breaker will continue to reset itself until the battery goes dead, I would suggest disconnecting the battery until you can get it to a shop. You have a short in the wiring somewhere. Good Luck!
