With the plugs out of the engine I can engage the starter and did three runs of 10 seconds that were about 20 mins in between each other and got 45psi oil pressure which is amazing. I put the plugs back in and wanted to test the battery system under a load. The engine turned over one compression stock and blew the 80amp ANL FUSE. 2 gauge wire going from the battery to contactor and then to the starter. 2 gauge ground cable from engine to ground buss. Help me lol
