every time i get in my car my clock always resets it never say the right time even if i set it and come back out in 30 minutes its reset. Where can i find a manual online for a 93 accord

The clock has three power sources. One is for the lighted segments, one which dims the clock segments when the headlights are on and the other is what causes your clock to keep time when the ignition switch is in the off positon. The last is from the same source that keeps the radio station memory and is powered through a 7.5 amp fuse located under the hood and feeds into the clock on the wht/yel wire. Remove the clock and check voltages. If they are there, you have a broken clock and the only option is to replace it.

How old is your battery? Sometimes this is the first sign that your battery is going bad.
