1973 Mercruiser 120- I can't get the motor to start. The coil wire won't arc to ground when cranked. I just replaced the coil. <br /><br />Just to check myself- There are two sets of wires coming out of the wire bundle. One which is "hot" and connected to the positive terminal of the coil. Another which carries no charge and is hooked to the negative terminal along with the negative wire from the distributor. <br /><br />With the ignition on, I'm getting 12 volts off of the hot wire before I connect it. Once connected it only reads 4 volts. I also get 4 volts off of the center terminal of the coil but even less at the distributor end of the coil wire.<br /><br />I saw one diagram where only the negative distributor wire was on the negative post of the coil and both other wires were on the pos. post. The hot wire came from the starter solenoid and the other went to a harness. I tried this set-up but had no luck that way either.<br /><br />Shouldn't I be getting 12 volts at the distributor end of the coil wire or am I just confused?<br /><br />Where should I go from here?<br /><br />Thanks in advance-
