Title: Instrument pod reassembly. Corona project 1
Post by: Martin on March 29, 2020, 07:34:50 PM
Amongst my recent K75s panel and bits was this. Although disassembled it looks in good condition and worth putting a bit of effort into. I'll either get it back together or go mad trying. 
Regards Martin.

Looks like a great project. Here in the states, it'd be a good chance to reset the odometer and turn the speedometer pot so it reads "mph" more accurately. The lenses look fantastic.

Martin, thanks for reminding me that the "new" K100RS cluster has a loose bulb in it that is blinking.  It will be a good project for the incarceration.

I was making progress until I found that I seem to be missing a circuit board. I'm using an early set of instruments as a reference which is different. Mine appears to never have had the larger board which is attached to the speedo face. I don't know whether I can remove the circuits from the early board to make it work. The early one has a red light next to the 4L fuel light with a small silver label with Japanese characters on it, a red and yellow wire goes from the light to the larger circuit board. Three wires black blue and red go from this board to the board that is missing.
Regards Martin.

I think the red warning light might be a speed warning light unique to Japan. I wish I could read Japanese. As such I could probably remove the circuit board that I want from the early speedo. However I am reluctant to do so because I have never seen this light fitted before and I would rather keep it as an early working speedo. I also have a couple of mates with early Bricks who might require it one day. If anyone has a wrecked speedo and is willing to part with the required circuit please contact me. At this stage the speedo is back together awaiting the circuit. I wound it forward to match mine then realised I should have left it on it's original mileage. I'll rectify that later.
Regards Martin.

Good try Vol the first two characters represent the word speed the next two characters represent alert. Still working on the fifth.
Regards Martin.

Thanks Skunky that's close to what I got. The first two characters translated as speed the second two characters translated as alert. I haven't bothered with number five.
Regards Martin.

During rebuild did you notice how the knob for trip odometer is attached to the rod that turns that meter? I ask because I have an pod that is missing that knob and I am wondering how I will fix that problem.

Tommy to remove it just give it a firm pull. To install it fit it in the hole and push. The knob should look like the picture. I some rare cases you might end up with just the black plastic piece. In that case I think you may be able to remove the back and reassemble the knob.
Regards Martin.

Thank you for the tip and picture. Now I have to find an used knob to replace my missing one.
