I have recently experienced a problem with the oil indicator light flashing on and later going off. Now, I have the reserve fuel light on even though the tank is half full. Finally, the antenna is only working intermittently. The oil level is topped off and the sending unit on the fuel cell is relatively new. Also, the upper wiring harness has been replaced. Is there any possible common wiring issue linked to these electrical problems or is it more likely that they are all individual problems to investigate. I am not sure whether the lower harness has been replaced, so I am wondering if this could be related to all the lights coming on and the antenna's inconsistent operation.
