Problems with Acewell speedo
Guys, I really need your advice on this!!
I've installed an ACE-3803 from acewell and hooked it up to it's sensors etc.
The problem I've got is that the speedo just jumps around in lower speeds (below 100km/h) Above that its stable and OK.
I've also temporay installed a bicycle computer just to double check and the reading above 100km/h is correct. I use tha same magnet fo both
sensors so the magnet seems to work.
Do you think that some kind of filter is needed on the DC (supply side of the instrument)?
Could it be something with the cable used for inducting sensor for RPM??
Any ideas, suggestions etc is most welcome!!

...forgot to mention that I use one magnet (as specified by supplier) mounted on the propshaft (if that changes things...)

Dont know if this will help, but when i installed my speedo I only put one magnet on the prop and got erratic speedo readings. I ended up putting four
on to get everything working properly.

Thanks for that idea. I understand that the sensor is "open" when the magnet is not present, due to that the input is sensitive to other
disturbances until the next time the magnet pulls the switch. By adding magnets the "open-time" decreases and the sensitvity would
hopefully decrease as well. I'll try that!!

Did you get any joy with this?
Only curious as Im thinking about an Acewell as an option but I want something reasonably easy to setup.
