Vin x027972x 720avhp transmission code 4.2 neutral switch now its electronic shifter so im thinking neutral switch is built in computer board ? its 8 pin pull a-h anyone have a clue where to start volvo has been 3 days waiting to get back to me on troubleshooting..lol
cant find a dianotic plug for comp hook up
There is a microswitch on the controller that can give problems. Try manipulating it manually. Use proper safety procedures. On review that may be applicable to an older machine with twin shift levers. My apologies.
this is single shifter but a button in front that could be micro switch but i dont see wires coming from it
also it will not crank over ..neutral transmission code is locking it out from cranking i guess
No I’m afraid I was thinking of an older unit. Remove the shifter and check the wiring. The later ones (Volvo) have wires bent at tight angles.
The button on front is merely a lock to keep the shifter from being bumped into gear.
Is that serial # a series 5?
Sir thats vin off tag ...I think i may have found one of the 2 problems
Tuesday morning i went in early and started looking around transmission of grader while no one was there ..i like alone time with equipment checking all wiring and connectors and found transmission fluid sight glass and it was dry ..3 quarts of oil and trans code has now left so im guessing its a safety for transmission code ..low in oil and no movement on transmission ..still no start so on to now on to 2nd problem i start looking at fuses, relays and wiring i had no current to a 50 amp relay 2 bigger red wires and 2 small plug in wires i traced to starter one big wire ..key switch one smaller wire i jumped the relay and she started right up and went into gear ..damnnnnnnnnnnnnn opening the relay up contacts are burnt bad so new one coming Thanks guys for trying to help
Continuous duty solenoid. Make sure you get the proper replacement. A normal momentary type won’t cut it. Glad you found your problem!
ok guys i finally got to get back to work on champion motorgrader and this is the main part of shifter problem its the shifter computer board
see the groove in back its from wear magnet was too close
Clean that rubbed out place real good with acetone and inspect for any electrical traces that might have been cut. Looking at your picture, I don't see any. If you find damage, it might be repairable.
