I've searched and read all of the replies to "alternator failures" on this site and believe I may have a shorted or cracked ground trace in or behind the dashboard.

Had a un-charged dead battery and only 11~12 volt rating at the battery with engine at 2000rpm. Replaced the alternator 3 times without any luck. Noticed that only the far right 2 lights on the dash was lit with the key at position2. Finally dived under the dashpanel and found the main plug loose. Tighten and everything was fine, all lights at the dash was on. 14 volt reading at battery happily being charged by the alternator.

A few days later, noticed that only the 2 far right lights were on again. Battery not charging again, but the plug was tight. Push around behind the dash area and surprised, everything was good again. Didn't notice anything loose.

Have checked every couple of days and notice that it would fail when cold (2 lights lit), but fine when warm (all lights lit). Anybody had this problem or have any suggestions?
