i HAVE A 05 SPORTSMAN 700EFI, THE SPEEDO FADES IN AND OUT, ON FOR 20 SECONDS, OUT FOR THE REST OF THE DAY. i KNOW AWD WILL NOT WORK WITH THE SPEEDO NOT WORKING. ANYTHING I CAN DO WITHOUT BUYING A NEW SPEEDO?

 

Check speedo wiring under pod where it ties to main harness. Had a 500 last week had same symptoms,ended up being wiring zip tied too tight,causing intermitent short to speedo.

 

THANK YOU.
ALSO i FORGOT TO MENTION. THE SPEEDO HAD/HAS A LOT OF MOISTURE UNDER THE GLASS.
WHAT DO YOU MEEN BY "UNDER THE POD"?

 

Moisture could be the problem then! Some poster have used hair dryers to remove moisture,some others have torn into their speedos! Should get more suggestions from other members! When I said "under pod" means take the 3 screws out on upper platic piece where speedo is,will separate from bottom "lower pod". Good luck hope you can solve your problem without a new speedo!

 

Thanks for everyone's help. I took the speedo off and apart. there was some moisture and corrosion biuldup on the circut board. I removed the corosion with some scotchgaurd and used a blowdryer to dry everything off. I put it all back together and everything lit up and worked properly. saved me $300 for a new speedo.
THANKS AGAIN

 

I had the same problem on mine ended up being a loose ground wire unde fron cover by the radiator (brown with black stripe I think) made a whole new ground posistion has worked fine ever since!
