Hello all Calibra fans.

First sorry about my english i'll try to explane how much i can

My Calibra X20XEV '95 have heated seats and there is the problem. When i put ONLY one seat warming up, battery lamp on dashboard it starts to glow slightly veeeeery low (you can see only in night) but when i put on aotherone ON (both) light intensifies.   

When i put lights, fog light, CD player, steam ( on 4 ) every one possible consumator (w/o seats heated), battery lamp do not light!! multimeter show 13.9-13.8 but when we put seat heated on show 13.7-13.6

We tested car battey with multimeter and everything is ok with battery and alternator. I check wires under seats and everything is ok with them, do not have broken wire or something like that.

Btw before 2,3 days ago i going to guys who work with wires and car instalation, he check battery with and w/o consumators and he say everything is perfect with battery/alternator i dont have reasont to worry.... yes but that lamp on dashboard worry me . Sorry for long post i hope you understand my bad english. Greetings
