RE: My 4K odometer isn't odometering...

Hey Mark, thanks for everything !!!   I followed your instructions and voila
The only misleading part was the "on the side of the speedo" part. At first,
when you said to take the white plastic cover off I thought you mean the
"whole white plastic cover".  I thought about it for a while though... 8-)
then I noticed the worm gear from the side of the speedo. Oh, thats what you
meant from "On the side of the speedo away from the tach is the offending
gear."  Anyway, I never do anything the right way the first time so once I
had everything back together I took it out on the road and of course the odo
was now working but the speedo WASN'T !  When I put the cover back on, the
needle had fallen below the stay pin so it couldn't move in a forward
direction. Ooops, take it apart AGAIN. Put it back together AGAIN. Cool! I
have speedo AND odo...  but remember what I said about doing it the right
way the first time ?  I have no dash lights !  I'm hoping it's the dimmer
switch. Recently I found that I would sometimes have to wiggle either the
main light switch or the dimmer switch to get the dash lights to work, now I
can wiggle all I want (the switch that is) and get nothing. As an
experiment, I shorted the switch with a wire to see if I got lights. Got a
nice spark but no lights ! Huhmm... should be just some high current
potentiometer right ???  Oh well, I think I have a spare in the basement
somewhere but in the meantime,

		does anyone have a suggestion on where to look first ???

Oh ya, I put the snowies on too while I was at it.  Guarantee for a mild
winter... 8-)
