Engine will turn over/crank but will not run

Locked Rotor is reported as an overcrank fault "OC".

You first need to verify the engine fails to crank, which is likely a starter motor or start circuit failure.

If the engine cranks three separate times and then the OC fault occurs, it simply means the engine did not run... more likely a fuel issue.

But either can be caused by numerous reasons.

How long since a tune-up? Any applicable trouble codes? Make sure battery has a full charge and battery cables all good on both ends, not just at the battery. Check your charging system. Engine cranking, your systems get battery voltage. Engine running, the systems get generator voltage, that can be several volt difference.
It's possible there is a problem with voltage drop, somewhere.
When problem is ongoing, if it cranks good but won't start, have a helper crank it while you check for spark at the plugs. Also check proper fuel pressure and fuel injector pulse. Try to find what your missing? You may have to check voltage drop on that system. Just my opinion.

Ensure any engine control switch is set to the run position, with the load disengaged. Manually set the air shut off valve (if fitted) to the run position (see Fig. 18), Turn the key switch to the start position, which will energize the solenoid allowing the engine to crank over for a few seconds then start.

Check the instrument panel is showing normal running oil pressure, and the ammeter for charge to the engine batteries.
Allow the engine to run for five minutes checking the instruments are reading correctly. Stop the engine and check the oil and coolant levels, replenish if necessary.

Yes , if there is an errror on the oil pressure switch or a low oil level then the engine will not be allowed to turn in. Check and refill oil, check the oil pressure switch , it can be clogged and so might not work.

it needs to be flashed after sitting for an extended period of time with 120v like a plug in

Replace battery with your choice of 12v products considering physical size, amp range and warranty. Lawn tractor batteries seem to have the least life/duty cycle. There are two methods of charging the battery used by Coleman. One is to charge the battery with charger/alternator coils installed under flywheel of the engine and second is to charge with built-in circuit in generator itself. Examine your wiring diagram to discover which you have. Simple test with volt meter will show if system is charging. Test voltage at battery with engine off, then start engine and retest looking for slightly higher voltage indicating charge. The charging system is like a trickle charger and not like your auto with initially high amp charge then taper to minimum. If your run your generator for long periods of time and you feel that the battery is being overcharged, then rig a switch to stop charging after one hour or longer. Good holiday

A bad generator will not charge the battery as the engine is running over a period of time the battery will run down on charge and there will not be enough power to turn the engine over

I suggest that you contact Logitech to see if the remote is replaceable. are you out of your warranty period? (This is 90 Day free support and 1 year for the Warranty period) Also, when contacting them, have this information ready:

The PID of the remote:
*found under the battery.
The P/N of the remote:
*also found under the battery.
The PID of the RF Wireless Extender:
The P/N of the RF Wireless Extender:
Full Name:
Phone number:
Street:
City/Town:
Country:
Zip/Postal Code:

also let them know that you have already updated the firmware.

The 'overcrank' error simply means it tried to start but never actually started. It cranked for an extended period. Check the fuel and starting issues you would normally check to start the engine.

Hello dogwillhunt,

It is normal for a two-way radio to generate some heat, especially during extended periods of long talk time. Consumer two-way radios tend to be much more susceptible to this because they tend to be constructed out of materials that do not dissipate heat very efficiently, such as polycarbonate and plastic. Periods of heavy transmit times also use additional power, causing the radio’s batteries to run down more quickly and require replacement or recharge. Use of the display backlight feature can generate additional heat and run the unit out of battery power even more quickly.

If the radio is heating up excessively and burning through batteries (pardon the pun) in situations where you are not using the LCD backlight excessively or transmitting for long periods of time, this may be indicative of a problem with the unit that would require service, such as a short or defective component. If such is the case, I would recommend contacting the manufacturer.
