Major Power Problems and lights on!!!!! ahhhh

Hey guys, we just got done swapping in a "fresher" H22 into my 97 base lude. So we start her up and the battery light, e-brake light and abs lights all stay on. In addition, when transporting it, the card drained a complete battery and I had to use the battery from my friend's civic to get me home. Any suggestions would be great. At this point I'm looking at a mutlitude of different reasons but I figure I would post up to see if someone already had this exact problem.

Thank you in advanced.

check your ecu fuse on driver side kick panel. should be a 15 amp. may have shorted it out with a sensor. this EXACT problem happened to me (although not sure about the battery drain problem) if you pop it in and it blows, you know you have a short. i would then start pulling sensor plugs and checking them. also make sure the right plugs are on the right sensors, there are about 4 plugs that are interchangeable, i did the same swap on my 97.

Thanks for the tip bro. I have another ground that I want to put in then I'll check that fuse. I'll update you tomorrow.

make sure the alternator is charging. measure voltage at the battery with the headlights off and then on. voltage should remain stable, if it doesnt read around 14 or so both times, theres a problem

Re: Major Power Problems and lights on!!!!! ahhhh

low voltage will cause the abs light to come on. as for the brake light, are you sure your master cylinder is full to the top of fluid?

Check ALL your grounds! I had one loose, made every light stay on, made the heat gauge read hot (when it wasn't even warmed up) and melted my throttle cable. (it was acting as a ground)

Re: Major Power Problems and lights on!!!!! ahhhh

that was my next suggestion. the ground wire that goes to the thermostat housing is VERY important, in fact the car won't even start without it

Re: Major Power Problems and lights on!!!!! ahhhh

Can you guys get me a picture of this wire. I don't see it. I did add another ground to the motor, just in case that was the case. Could it be the ignition?

Re: Major Power Problems and lights on!!!!! ahhhh

The wire that was loose on my engine is next to the Timing Belt. It runs from the side of the engine to the chassis.(just a few inches long) There is also a smaller ground wire that runs from the Valve Cover, and splices into the bigger wire that I just mentioned. The wire on the thermostat housing is pretty obvious. there are 3 bolts around the housing. 2 of them hold the housing in place, the 3rd bolt (looks like it holds the housing on, but doesn't) has a little black wire connected to it. Make sure to check your main ground from the battery too. I took all the wires off, and cleaned the the connections and cleaned where the grounds bolt in. I learned the Prelude is very finicky with any of these loose or corroded.

This ground was close to the same on the motor swap I did on my 1990 SI 3rd gen. There is a bolt that is threaded into the block near the thermostat housing. Look at your upper radiator hose trace that back to where it connects to the engine. Look in that area you should see about two threads holes into the engine block itself. If you don't have a bolt with a couple black wires there then I'd say you have an un grounded ground. I missed this ground myself with my B21A1 swap in my 90. After I connected it it was golden. Good luck I hope this fixes it.

Yea, I see where that ground would be but there isn't a bolt or a ground wire. I'm looking at the schematics, but don't see where that ground wire is at!

On the H23a1, the thermostat housing is on the lower radiator hose, not upper. That is where the ground wire is on mine.

Yea, I put my battery back in, so we can mark that off. Thanks for that tip. I didn't know that!
