a few days ago there was a post about speedometers. someone posted a link to a digital, battery powered speedo on e-bay for $2.94 (from hong kong).
i'm just wondering if they got it to work (whoever it was said that he bought 3 of them).
well, i bought one and i did get it to work...until i started my motor.
as soon as i start the motor, the speedo wigs out, resets itself, and then all the numbers lock on 8888888.
it works fine without the motor running, and i tried several different things to isolate it from touching anything on my bike. i even went as far as taking it completely off my bike and holding the entire thing in my hand. sitting on my bike i can fire the motor up with the speedo in my hand, and it does the same thing as when it is attached to the bike. (resets, and all #'s lock on 888888).
i was just wondering if the other guy got his to work, and if he had the same problem that i am having.
since this thing is battery powered, and is totally encased in plastic, i can not figure out why it messes up when i start the motor. I even went as far as totally disconnecting my cdi box from the frame thinking that it is sending current out to the frame.
for some reason, it seems like my entire frame is "charged" when the motor is running. i had the same problem when trying to hook up a headlight to the white wire....but that's a whole different story.
all of my wiring has been soldered, sealed with heat shrink, and wrapped in plastic convolluted tubing. no bare wires are touching anything, and my motor is isolated from the frame with rubber pads.
i can not figure out what is causing this.
