We bought our daughter a 2001 xj last year. It came with an aftermaket fan assembly consisting of 3 fans. I had noticed in the past year one of the fuses on the fan harness had completely melted away (holder and all). We reconnected the wires but now we notice they are intermittent, battery issues (very random battery no start). These fans look relatively new, can we put an amp meter on the line? or is there another test?
