Default Re: Intercooler pump fuse keeps blowing.
I would look at the socket, if the pins are loose the terminals will heat up and even normal current levels will melt the fuse material.

Look at the fuse and see if the fuse is melted of smokey blown. Smokey looking plastic is a high current overload and indicative of a shorted connection or a commutator that is having problems in the pump motor.

In the short term, you could replace a higher amperage fuse, upping it no more than about 5 amps once to see if that is sufficient or if the problem is more than that.

If you wanna unplug your pump and install a fuse and drive around for a while, youll know it there is a short. With the pump unplugged the fuse should NEVER blow/melt, just as a hint.

BTW my Johnson pump is still ok on the stock fuse..........ENJOY
