never had a wiring problem, but i have the bolts shear off the pump head, and it fly off on one 450, and a leadhose blow on the other, both in the same day before....
well from my past few expiriences if your wire gauge is too small it could burn up the wires... whether its fused or not...too small of a relay or.. not enough... it can be numerous things but those are the few problems i had when i was younger and didnt spend that extra cash to make sure my shit wouldnt burn up
if i was runnin 2 viairs 480 i would run 4 gauge fused and a distribution block split off to 8 gauge and also fuse that and a big ass relay and im tired off typing ammmmm,df
yea im running 2 air zeniths off 4 gauge split to 8 gauge, not one problem, i got some high amp selinoids from autozone too cause my relay friend
well i figured out that my compressors are still good.......now its looking like my wiring might be off......
so imma take a closer look at it when my buddy shows up....
