Possible electric problem?
yes hes talking about the amp meter wires. a lot of people bypass the meter and it takes care of their problems but you need to start at the battery and get yourself a 12 v test light and check for voltage to stater , starter relay, to bulk head and into igntion switch. if it wont turn at all try like your dad did and jump across the big red wire at the starter relay to the wire running down to the starter , you should turn over the motor if you have battery voltage. what year car is this ? is it points ignition or electronic?
