I bought a scraper blade for my T300 and when I hooked the hydraulic hoses to the machine,I angled the blade and it blowed a fuse in the fuse block causing the unit to shut down. I checked the fuses in the fuse panel and the 25 amp fuse for the computer was blown. I put another fuse in it and it blew it as well. Any ideas on what to look for or where to look? It smelled hot before the unit shut down. Thx
