I own an ASV track loader(SR80) but my neighbor is having problems with his newer, CAT 277C. Trying to help him; he has problems understanding the situation. . . but I have never even used his machine. (He has owned and used it successfully for a year since buying it used. In pretty nice condition.)
He has been used to starting it up and using only joystick pattern #1(Cat default logic), then pressing the Parking brake button to release the machine and start usage. Normally, after doing so he simply starts using the machine as required.
I had him demo how his problem shows up as symptoms:
-- Out of the blue, after NORMAL start up(select #1, deselect Park) the machine is locked in place or runs intermittently, wonky. . . not right, whatever.
-- I started up the machine yesterday and watched him do so also. It appears the "1 /2" joystick pattern selector toggle switch is intermittent and possibly faulty. Pushing it multiple times on the left and right finally pulls it out of the blinking mode and one or the other(1 or 2) engages. However, once engaged still, nothing works / moves or if so, not correctly or as expected.
-- a flashing, yellow warning triangle appears with ! in the center. But, no way to understand what is wrong. . .?
After replacing both the pattern select(1 or 2) and the Park toggle switches, some of the odd functioning was stopped but it is still nearly impossible to move as it eventually(minute or two) drops out and the yellow ! triangle flashes; making it immobile.
Questions:
1) Are there OTHER failsafe / lockouts that could be causing this inability to move and use the machine after it is running?
2) ways to find out what the triangle ! is alerting to? Is there a diagnostic connector you can buy like for a car?
THANKS for your time!
