Hi Bob - Ouch! Check the fuses. That's where I'd start. Do you have the tech manual for the 318? The TDC module may have been affected, since the battery light circuit goes through that unit. Chances are, the voltage regulator is toast, but maybe not. The circuit breaker may be fried. It's on the right side of the pedestal, under the green sheet metal. Disconnect the wires from the terminals and check the terminals for continuity (ohms). If you have none, then the circuit breaker is OK. If any ohms register, the circuit breaker blew. - Dave
