The one and three wire alternators are the same except for the regulator. The three wire regulator has the two wire plug on it, no plug on the one-wire, naturally. One of the wires on the plug goes to switched battery voltage, or you can run a jumper from the big battery wire to that position, essentially making the three-wire alternator a one-wire. The second wire in the plug goes to the dash light. So you can easily use a common three-wire alternator. ----------------- Date: Mon, 14 Mar 2011 17:21:46 -0700 From: tom jennings<tomj@xxxxxxx> Yeah you really want the three wire alt - fat charging wire, one to the dash light, 3rd also goes to battery to measure battery voltage. Batteries will last longer. -- Frank Swygert Publisher, "American Motors Cars" Magazine (AMC) For all AMC enthusiasts http://www.amc-mag.com (free download available!) _______________________________________________ AMC-list mailing list AMC-list@xxxxxxxxxxxxxxxxx http://list.amc-list.com/listinfo.cgi/amc-list-amc-list.com
