1991 CRX si. i have no power to my radio and my clock. the rear interior trunkilight doesnt work either. The clock only works if i push the button down to see the time when the car is off, and it says 1:00 i cant seem to find the answer to this problem. looked in to the fuse under the dash. the radio one "15amp" was fine. changed to another "15amp" still didnt work. any help is appreciated!!!! thanks in advance!!!

similar problem in this post for an integra, i dont know if we have the same under the hood fuse though https://honda-tech.com/zerothread?id=1187027

The items aren't fried.....replaced clock, radio, and domelight with 100% KNOWN working ones. So, then it must be a main relay somwhere, right? or maybe a fuse in the under the hood fuse box (i checked all these fuses and they did not look blown)??

 

Exactly the same problem. Checked all uses under the hood and under the steering, 2 were blown and replaced both but the clock still doesn't work. The stereo works fine so I think I may have a wiring problem where the clock is concerned.

Any help on this would hugely be appreciated

 

If I can accurately recall this situation, I think my problem was that the current fuse didn't LOOK blown, but after no help I tested it with a multimeter and it tested bad (no continuity).

It was also coincidental that the fuse I found in my car's coin pocket that I replaced it with was also bad. I ended up testing the suspect fuses with a multi-meter for continuity and replaced any bad ones I found. I think I may have had 2 different fuses that looked good but were actually bad.

After I replaced the fuse(s) it worked fine.

Try testing them with a multimeter and report back.

 

"typically" a fuse problem. Do as above and double/triple check yourself

 

How was the 7.5A (I think) backup fuse? This feeds power to the clock and radio to keep the memory... don't think it'll keep the radio from working but worth a shot.

Next step would be to check all the fuses under the hood and under the dash with a test light or voltmeter, check the ones under the dash with the ignition on.

 

You can test fuses without pulling them with a multimeter. Probe those two exposed metal pieces on the back of the fuse with the continuity tester.
