1997 Gmc 2500 350 with a 5 speed. Truck keeps blowing gauge fuse. Pulled gauge cluster and still pops immediately. Tried pulling headlight switch no luck, Pulled every fuse in truck (Including under hood fuses) and same result. Is there anything else i can look into? or can someone else supply me with a wiring diagram for fuse cluster to gauge cluster? On a side note alternator isn't charging either, replaced with a known good one and still nothing, are both issues possibly related? Thanks Justin.
