    Isolator install instructions, splice wire to alternator IG wire from isolator E post. My alternator has one blue, yellow, white, I tested all wires and found the white wire had no power on acc and power on run. According to instructions this is the IG wire. After installing wire to alternator batt post and isolator A post. I have no power to A post, it should be 13.8 to 14.5 volts. I have repeated this with the red and blue wires with no success. Very confusing these instructions are for a series 2 alternator. I own a 2001 4cy 2wd Tacoma. Please HELP!
