Seeking input and guidance:
Started the machine in the morning. Fired right up...no hesitation. Ran it for an hour and shut it down. Came back to it after an hour and tried to start it..turned the ignition on...had power....turned the key to start...nothing...No sound of the starter trying to turn....just nothing....other than what normally appears on the monitor when turning the power on...but when trying to start...nothing...not even a click.
* Checked fuses - all good
* Disconnected batteries and load tested each - both good - Reconnected batteries
* Turned power back on at the key switch - tried to start - still nothing
* Checked for power at the battery relay and at the starter. Powerat both. Banged on the starter - nothing
* With power on tried jumping the starter - nothing - ok - bad starter - took it out and saw that the drive pinion was
stuck out - had not retracted -must have burnt the starter.
* Replaced Starter -
-----------------------------------------------------
When I replaced the starter I did not give much or any thought to what might have caused this to happen to the starter and this is where things get interesting.
Installed the new starter - Tried starting - NOTHING - same exact nothing as described earlier in this post. Repeated the steps above and when I got to jumping the starter it fired right up - It fired up with a new fault message "EG REV SENSOR". (replaced that straight away - it had frayed wiring making an intermittent connection.)
We are a busy facility and since I was able to start the machine by jumping the starter the decision was made to put the machine back to work and continue diagnosing the problem if and when we could. (no input or guidance needed on this point....I get it....and didn't like this approach either)
For several years prior to my arrival the machine has been started with a screw driver rather than a key in the original ignition switch...not knowing if this was part of or the problem I thought it would be good to replace it regardless and thus we did.
So at this point the machine can be started by jumping the starter and has gone back to work for about a week.
After about a week one of the guys is working the machine and loses use of all hydraulic functions and notices the monitor displaying several different fault messages. He tries to shut the machine down at the ignition but when he turns the key to off the electronics turn off but the machine does not shut down...had to shut it down at the engine.
I load tested each battery - batteries dead and could not take a charge. Replaced batteries and was able to start the machine at the starter....so....now we are back where we started except that the machine is now also not properly charging the batteries.
Downed the machine and looking for resolution. Found that now the battery relay that sends power to the starter went bad....but replacing it did not resolve the issue...still no start.
To date we have replaced the following:
*Starter
*Ignition Switch
*Battery Relay
*Batteries
*Fuses all good
Have power - can only start by jumping the starter and won't charge
HELP!
