I just got my replacement alternator today, and I noticed an extra spade-type plug just off the center at the back of the alternator.<br /><br />It's marked with a lettter 'P'<br />What is this for?<br /><br />My original alternator only has a battery lug, ground lug and a 2-pin plug that snaps into place. <br /><br />This new alternator suppose to be a direct replacement. It also has the battery, ground and the 2-pin plug, but I have no idea what the spade plug is for. I hope I didn't get the wrong alternator?<br /><br />My original alternator was Mercruiser part # 862031 (Delco)<br />My replacement is: Delco 19020609 7SI series.<br /><br /><br />Thanks,<br /><br />H.
<br /><br /><br />I'm guessing the extra plug might be for a automatic choke or?<br /><br />I'll hook it up tonight and see.<br /><br />H.
