I have an older honda ex 1000 that just will not charge,

Check the wiring, especially the engine earth lead.

That's usually the sign of a clogged or restricted condenser or expansion device or both. It's not just a switch. The only way to know is to do more diagnostic work to nail down the problem

Normally a generator RPM dictates the frequency. You will have to obtain a frequency meter. (Some multi-meters include a Hz selection). Adjust the RPM until your frequency meter shows 60HZ (in the US). If you do not read any frequency at any RPM, the unit needs troubleshooting in the voltage section.

there are like 1000:1 posts on how to kill a chime.
must be some one beat you to it? LOL

and NO, the EX Civic has chime, not cheaper models.
but the key chime should work.
do you need the drawing of the ICU to trouble shoot it.
its free and in on the honda forum. 1000 of posts on topic.

check your battery connections then charge the battery over night then check the charging system

Check and see if timing belt jumped . The belt may be missing a couple of teeth

have your charging system checked, you may have a bad Altenator

Change the ignition switch at key.

Factory radio? If so, ONLY the dealer can help...They might do it free...my guess is they'll charge you $40.
Good Luck

check your throttle cable or most of the times its your o2 sensor remove it while the car is on and it should stop so replace them
