Compressor popping fuses

I'm hopeing to get some help. I have two Viair 380's and i keep blowing the fuse going to both of them. The fuse is a 60 amp. I have one 8 guage power wire going to a solenoid to where the two compressors are hooked up to. I have had my truck bagged for about 8 months now and have never blown through any fuses. I went through 6 fuses over the weekend!!! I checked out the wires and they look good. No rips or anything. So i disconnected one of the compressors and only ran one compressor on a 50 amp fuse and it hasnt popped yet. The only thing that i can think of is that the wires from the compressors that go through the bed floor are frayed and are grounding out. I havent got a chance to get up under there and check it out. Has anybody else had this problem??? Also, could it be that i need a high output alternater. I have a yellowtop Optima and have one amp in the cab, but my headlights dont dim or anything. If anybody could shout out some help i would appreciate it!!!

probably grounding out,put a grommet in the floor where the wires go through.It doesnt need another alternator,if you were having voltage problems you would draw less power and shouldnt blow fuses.Try rewiring compressors for a week just jimmy rigged so you can see the wires.

use a relay
