thanks for the great information , i had already pulled the resistor and found it was 200ohm.
i agree that just paralleling additional resisotrs is easier and less strain on the board...had that happen before. so i think what i'll do is get an upgraded cincon to 15 v and put low value resistors on the existing ones.
as for a laser temperature probe....no go...
but lets try the other stuff first...if theres still a problem then we'll see
thanks again,
let you know how it goes.
