I just put a new engine in a 92 accord (f22A) and I finally got the car running great. I took it out for a drive and noticed the D4 light was flashing I parked the car and turned it off. I came back outside an hour later and the car is 100% dead. No electrical systems whatsoever. It wont turn over, no light, nada. checked battery connections with no luck. What am I missing

 

BUMP

 

have you checked your battery? plz dont tell me its a known good battery. check it. have to read 12.4 if its below its a bad battery. if its good grab a multimeter put the ground probe on the batter and the positive prob on the positive side of the fuse box under the hood. open the fuse box panel theres two Philips screws on there what your aiming for is the one closest to the fender put the probe on that and see if you get power. its circled in the black circle with the red arrow pointing to it. plz excuse the other arrows that was done for a fog light diy. once youve done that check back here and post the results

 

That was it. I must have forgotten to tighten after the swap. What I mean is the power in the fuse box. Thanks so much

 

no problem good luck with your car and have a nice day
