One thing that puzzels me... ( and I am in a "thinking loud" mode <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" /> <img src="/forums/images/graemlins/lol.gif" alt="" />) is as I said in the first place the big electrik cosumption of the big fan running all the time when the A/C is on...
I syspect but couldnot find any information on the speks of the original A/C fan....

If the altenator can(????) manage it together with some lights a hot summer night stuck in traffik, then ok....
Because the bigg fan runs all thetime instead of the small one
