Hello,

 

i purchased some ingaglo dials, and unfortunately they are different.

 

Turns out, my speedo (which is in KM/H and why am changing dials) is off.

 

Is there a simple resistor change or something to adjust the speedo range? Mine is a 120MPH speedo, and the replacements are a 180MPH face.

 

Many thanks, as I don't really want to purchase a new speedo cluster, or new indaglo dials.

 

I know... should have checked first...

From memory I think you need a 20K resistor, but if you search for "speedo resistor" I'm sure you'll find a few results.

For future reference:

 

R10 in my dials was 33k and needs to be replaced with a 20k resistor. Then a little tweaking of the variable resistors.

 

KM :: VR1 :: VR2 :: R10 :: VR1+R10 :: Country

300 :: 9.93 :: 1.733 :: 15 :: 24.93 :: US/JP/AUS

280 :: 9.18 :: 0 :: 20 :: 29.18 :: EU

180 :: 8.94 :: 0.969 :: 33 :: 41.94 :: AU/JP

What you would have been best doing is buying the Indiglo faces in KMH, and then have a proper and full import mph conversion that would calibrate your needle movement, delimit, and adjust all your odometer and trip recordings in one swoop.

 

Any chance you can swap your faces?

 

The kit for this conversion is no secret, but not many seem to use the proper and full box of tricks and you can end up with a half converted speedo that is less than accurate too!

 

cheers

ps - good luck
