Is your shift lever lit with the key on?
Here's a wiring diagram.

Somebody didn't throw the on -off switch back in the engine compartment did they?
Check and see if you have some spade fuses connected on the top of your chassis batterys that might have failed. Sounds like you lost power to the ign switch.

My engine ECU and tranny fuses are separate inline fuses located on the left side of the chassis battery compartment.

Sounds like your chassis batteries are discharged below what the ECU's require.

Rex, I agree with you. That sounds right about the chassis batteries being too low. Easy to check using the dash volt meter gauge or with a volt meter. The other thing would be to try and start the motor while holding down the BAT BOOST switch.

If the generator will start you should run it about 30 minutes and then try again.
