I have a generator that the battery blew up.  I replaced the battery and charger.  When I put the generator in auto mode it starts and will not shut off until I put it in off mode.  Wondering if the control module is bad.

Test the N1 and N2 fuses.

Model and SN will help but the N-1 & N-2 fuses as was suggested are the most likely.

55010 model.  I did test the fuses and they are good

The sensing fuses in this style of generator have to be removed and tested with a continuity tester.  Checking for voltage on the load side of the fuse will not do because if the other sensing fuse is good there will be voltage on both sides of the blown fuse.

After checking the fuses locate the transformer in the center-right of the wiring compartment.  It has two separate secondaries.  The two terminals toward the rear is one and the two on the front side is the other.  Do not disconnect any wires from the transformer.  Check for AC volts on each secondary (top), each should read about 18 volts AC.  

If 18 volts is not present, check the two primary terminals on the bottom of the transformer for 240 Volts ac.  If you do have 240, then the transformer is bad.  If you do not have 240, then a fuse is blown or there is a wiring problem.

It's possible that there is nothing wrong and it is trying to run an exercise.  If the green light is not flashing while in Auto and no transfer occurs shortly after it starts, it is probably that.  If the green does flash when placed into Auto, then the generator is not seeing utility power (18 volts).
State your problem, not your diagnosis.

I will do a continuity test today.  Thanks
I did check voltage only

I tested all 3 fuses with continuity tester.  All is good.
I'm not seeing this transformer as indicated in the above response

This is a 2008 series 8 KW which does not have a transformer separate from the controller.  If all the connections into the controller are good and I would recommend taking the control pane out of it's box and check the back thenI would most likely think the control panel is bad.

The generator is not in transfer mode.  I have 120 volts on N1 and N2.  
I will order a new control panel
Thanks

You should have 240 volts on N1 and N2.

I'm assuming he means measuring from N1 to neutral and N2 to neutral even though he stated it wrong.  Seems we blew the diagnostics off and went straight for the most mysterious part, the circuit board.  I'm out.

, told me this was going to be short and sweet.

An open wire or fuse on either N1 and N2 will still show 120V from either line to ground (or neutral) when measured with a high impedance multimeter. He needs to check between N1 and N2 for 240V.

MacL, while I agree that we’re jumping to conclusions here he said he checked the fuses individually with an ohm meter so he should have 240 Line to Line.  I asked that the controller connections be checked by removing it from its box but since there isn’t a step down transformer on this model not much else to check.

He needs to verify 240v on n1 and n2 AT THE CONTROLLER BOARD before condemning the controller itself. 
Or, just throw money at it until he stumbles on the problem.
