15 A Fuse keeps blowing

[jueshen]

hey guys, been running my HFS2 kit for 6+ years the one with the 160psi pump.

anyway for 5 years i had no major issues, just the nozzles clogging.

and this year since feb its has blown the 15a fuse every month since feb.
so im on the 5th fuse now - nothing has changed, cleaned the relay and battery terminal after replacing the last fuse

only thing i can think off is my car batter is 3+ years maybe its supplying less current, so the wmi pump draws extra to compensate and blows the fuse?

i would love to throw in a 20a but i dont want any fires!:cry:
