Wassel woes with Koso speedos....

[carlos fandango]

Well the rev counter part not the speedo , but rev counter didnt rhyme
Ive had this speedo fitted for 6 months.

The speedo part is spot on, but i cant get a stable reading from the rev counter no matter what i try ive spoken to the suppliers who sent me a different sensor thingy to try but its still the same

Now i seem to remember something about the SIP speedos (which i believe are made by Koso) having problems if using a wassel conversion ?

I cant understand why a Wassel conversion would make a difference as the sensor/ pick up wire is just wraped around the HT lead

So is anyone else having problems with a wassel and rev counters ? (I know " sideout" is, thanks for the reply). I just need to know if it is the wassel conversion before i send it back as faulty .

Sorry to sidetrack this a bit but why did you do the conversion ??
I had mine done as I was told I wouldn't believe the power of my lights after, I don't
That nice mr Diablo tried to get the SiP speedo working for me, he couldn't.

Timbo had one fitted by bedlams scooters and they got his to work

Didn't he cure Timbo's issue with a resistor type spark plug cap? Try that Carlos. Stops the High Voltage pulses interfering with the rev counter.

I did it for better lights as well, i wouldnt say they are brighter and i didnt think they would be. I just didnt want them dimming when apply the brake or flickering at low rpm, and they dont now. i also wanted a better horn and the ability to run accessories. In retrospect i could have done this by just fitting a battery and rectifier but i thought the wassel would charge the battery quicker, which im not convinced it does

So it looks like only two people are having probs with the wassel and the speedos
Ill have to change it to a AC and a trickle charger and see if this makes any difference.

Yes that was the first thing i did, as it say to do it in the instructions. I even changed the cap to a resistor one still the same

b@11@x, thought we'd sussed it:(

I know this thread is about the Kosso rev counter but the Wassel convertion should not have any effect on your Kosso providing it can be operated from a DC supply (the SIP is a different problem). You are partly right about the lights not being brighter though, I don't recall it being said that they would be in the original posts on the subject although if an LED rear is used it will be brighter than if lit by AC and will free up enough wattage to allow the use of a decent Zenon headlamp bulb. However, as you quite rightly point out, the lack of dimming and adecent horn as well as lights that stay on when the engine cuts are reason enough. The simpler system with a half wave trickle charge will NOT charge the battery as quickly and you won't be able to wire your lights in, they would have to be AC.

... one of the yellows out of the stator while its still a/c ...

do you regulate that at all ? the voltage there can be 30,40,50...all over the place... tachos can be sensitive to voltage variations.... although i have never tried a koso one

... it mostly works.

[carlos fandango]

surely the rpm will work from one of the yellows out of the stator while its still a/c before it gets to the wassel? that how i have my koso wired and it mostly works.

Im not taking wiring tips from you ive seen inside your legshield toolbox a mass of wires, with blue electrical tape holding it all together

Ive wired it as per the instructions
