Gage Cluster Circuit Board

[fredderf]

Does anyone have a schematic for the two circuit cards that are located on the back of the instrument cluster? I found a burnt transistor see attached photo. My tach quit working and this is what I found. Does the tach go bad and cause this? Any input would be appriciated! It would be nice to fix it for .50 if I could get a part number that I could cross referance. It won't let me attach the photo since I posted it in the parts wanted section. Thanks in Advance

Here is a link for you.

Here is a schematic to the circuit boards! It is page 1110 of teeh scanned service manual. Good luck!

Brian,

Thanks for the post, however what Im trying to find is the actual schematic for the circuit board. I had found the wiring diagram that you had posted the link to. Thanks for taking the time to post the link to it. I removed the dash cluster and found a burnt transistor, trying to find the actual part number or a comparable part to replace it with. Honda must buy so many parts that they get them supplied with a honda ref# on them instead of the actual part#, if I had the schematic then I could figure out if it's a power regulator or a pnp,npn etc. Then I could fix it for less than a $... Thanks again...Lyle

I rather imagine that you will need to contact Honda directly for the info you seek. Dealers do r&r on things like the circuit board but don't deal w/ the individual components on the boards. If you provide them with the ref. # they should be able to provide the info.

I'm not sure how to contact them directly however. Anyone with an email address or website?

I think getting actual drawings of the circuit-board, as in 'schematics' is next to impossible. I have been into car-electronics, and all schematics are kept locked away.

But really, you don't need schematics, all you need is a good board to check the partnumbers on the components, and replace them (if they are not customized), and get someone who knows electronics inside-out to find out the reason why the particular circuit went.

Maybe getting a used replacement is the way to go.


Succes
