If you try to read anything higher it will simply display OL (for overload) or something else to prompt you to change the range. 2.5 on this range means 2.5 Ohms, which is too low; that would draw 4-6 amps and deliver ~75 watts, but still shouldn't blow a 16A fuse. You will have to "divide and conquer" which means that you disconnect some of the loads to try to find out which ones are the problem. > I will disconnect the CD player and then test for shorts--there is a > short, but I'm quite positive it is cause of the CD player, then again > the FP and it are on the same fuse so it may turn out to be that wire to > the AAR. Take a look at the Bentley for the specific fuse box allocation for your year. VW left one fuse unused each year to be used by aftermarket installed equipment, like a radio. The fuel pump and AAR should not share a fuse with any other items. -- Jim Adney jadney@vwtype3.org Madison, WI 53711-3054 USA ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ List info at http://www.vwtype3.org/list | mailto:gregm@vwtype3.org
