Get rid of the ammeter,and run a voltmeter! I kept my stock ammeter (dis-connected),just for looks,but installed a voltmeter under the dash,to monitor my circuits. An ammeter cannot support the extra voltage from an alternator! They're wired in series,with no fusible link,and they can over-heat very quickly. I installed a kit from A.A.W.,and on almost every installation page,there was a warning on this subject. Hope this helps.
