Hi all, I've got GTS guages' cluster in my HJ Panel van. The issue is that when it's cold the Alt/Gen Guage goes right up above the Red upon acceleration, to the point it cuts out my cd player. It returns to normal upon deacceleration. Once it's warmed up the needle sits where it should and no further problem. I need a bit of advice as to the cause. I'm thinking my Alternator is on the way out but am to a loss as to why it's normal when warm. Any thoughts Thanx
