Hi, Actually have a couple problems which may be related. Original issue started a couple years ago where turning the key the engine would crank but not start. Turning Ign on/start/off/on/start/off until engine fires has me thinking it may be the Ign switch. Now the tach and speedo as well as the radio cut in and out occasionally but the engine still runs. Looking at the schematic I see they're all associated with both the drivers side underdash fuse/relay panel and the passenger side underdash fuse/relay panel. Unfortunately, my schematic doesn't show where power to thes fuse panels comes from. My guess is the ign. switch. Anyone have an idea?
Thank You

Hi Larry

Yes you are correct about the power supply coming from the ignition switch.

What you have could be a problem with the ignition switch or a loose connection somewhere that is causing intermittent failure.

A safety recall was issues for the ignition switch and you can call the nearest Honda dealer for clarification if your vehicle qualifies for the recall if you have not have the ignition switch replaced yet.

Thanks for the info. There is no recall on my particular model. I wiggle the key in the ignition but can't seem to duplicate the problem so thinking it may be elsewhere. Any ideas as to location of plugs, fuses or relays which might cause this? I'm thinking if I attach a small light to the circuit at various points I might be able to isolate the problem.

Even if your vehicle is not under the recall, we cannot rule out the possibility of a failing igniton switch.

It is quite common for them to fail over time.

While driving, test the ignition switch by feeling the rear part to see if it is excessively hot. If yes, the contacts are not too good and will cause intermittent failing.
