Default blowing fuses 15A

I have a V3 with analog brain and its blowing the 15A fuse. I drove it straight for 1200 miles two ways and for the last 100 mi the green light went off and the V3 stopped pumping. I checked the fuses the 15A was blown so I replaced it, drove it until it warmed up and when the green light went on the fuse blew again in less than 10 seconds. When I turn the system on in manual mode the green light goes on but no pumping. Any suggestions are greatly appreciated because I am about to take another 5K mi trip in one week. Thanks

Default Did your pump lock up

What I would do is remove pump from system and turn on in manual mode. Likely locked up
