I just finished my DPFI to MPFI conversion on my 91 Civic DX...I was in the process of connecting my battery, saw a small spark and eventually I discovered the 60A battery fuse (in the engine bay fuse compartment) had gone...so i went out and bought a new one and the same thing happened...any ideas?...did i connect it wrong? I connected the positve terminal first then the negative...it is also a brand new battery which i had no problems with before the conversion...thanks

 

actually nevermind...got it fixed...stupid mistake and conversion was almost succesful...only 2 codes!
