I just installed a fresh ls/vtec motor in the 96 integra. I went to connect the battery cables and pop goes the 100A battery fuse. I tried installing another but it popped also. So I have a major short somewhere, how the hell do I go about finding it. My 02 sensor wiring is disconnected along with my coolent temp sensor on the head, maybe this has something to do with it? I also degreased the engine bay while the motor was out, I doubt it but could this have screwed up my harness?

 

you have a short somewhere on the battery cable

inspect it from the pos post down to the starter.

 

check your grounds aswell...when i put my motor in my old hatch i kept doing that lolol..oh well u live to learn
