Re: 906h no crank no start

Ended up being the batt kill switch or starter kill switch (whatever it's called) not allowing the macine to ground. Bypassed it for now and all is well!

Re: 906h no crank no start

It looks like you've done all of the trouble shooting we might recommend (battery testing, relays, etc.). At this point you may want to consider a call to your local Cat dealer.  They can send out an Electronic Technician to diagnose the issue. Since the engine start is controlled by software, this will allow them to see all of the inputs and outputs, and what the current status is while holding the key in crank position. http://www.cat.com/en_US/support/dealer-locator.html

906h no crank no start

2008? 906h 0* day one of the guys went to start it to load salt truck and it acted like the batt was dead. Load tested battery 12.8v 940cca. Batt also only 4 months old, have power to fuse panel played the relay game swapping around no dice. No lights on "dash" like it normally would but can hear glow plugs turn on with switch. Been fine on previous 0* days first no crank no start issue this year.
