Re: 88JohnsonGt 150
In technician training courses, they have a saying that goes "Garbage in, garbage out..."<br />You say everything is ok, but you've got to help us by defining "ok". Basic CD Ignition theory: magnets attached to the outer rim of the flywheel (when viewed from the under-side) rotate around the charge coils to produce somewhere between 250-300 volts. This voltage is stored in a charge capacitor in the power pack. Another magnet attached to the hub of the flywheel rotates past sensor coils, the sensor coils (1 for each cylinder) generate 1 to 3 volts. The lo-voltage is sent to the powerpack and controls ignition timing. <br /><br />In order to develop the correct voltage, the engine has to turn fast enough (battery fully charged?). Too slow and you've got "garbage in..." Can you tell us what the charge coil voltage is?<br /><br />1988/89 was the time-frame "QuickStart" was introduced - does this enine have it and if so, has its function been tested? To determine if your motor has this feature, look at the port temp switch wire(s). If its got QuickStart, they'll be 2 wires, 1 tan, 1 white with a blck stripe.<br /><br />-John
