Help, LCD problem on Argo 750 HDI

[dovkin12]

Hey guys it`s my first post on this nice fourm, Unfortunately with a problem on one of my Argo`s.

The LCD goes fine when turn the switch all leds are on. But when I start the engine LCD shows wrong RPM, Speed, Hours, and Milage. also when I do turn the throttle tube for more power the column with bars of the accmulator start flashing. may some help me solve this "enigma".

You can check the connecter from display to harness in the engine compartment. Also follow the harness to the ground wire. I've had to replace several displays with missing or improper readings. If you have two vehicles with the same display it's not difficult to swap out to verify if the failure is internal. They have to be programmed for proper tire size. I believe Baked Alaskan posted the programming procedure on this forum last year.

Thank you very much "msafi65" for the reset instructions, I`ve tried them, helped to make the RPM working well.

Your Argo dealer should have a copy of tech bulletin 204 that tells you how to reset or calibrate the digital gauge.
