First, lets get the right documentation in your hand for the generator you have (7.0 HGJAB).

Operators Manual: http://www.cumminsonan.com/www/pdf/m.../983-0101B.pdf

Service Manual: http://www.cumminsonan.com/www/pdf/m.../983-0501D.pdf

This is a computerized generator so the first thing you want to do is see if there is a fault code. Turn to the Troubleshooting section of the service manual and start there. That tells you how to read the fault codes and points you to the appropriate section of the manual.

This is a dual magneto spark system. 12VDC is not used to drive the coil and spark plugs. Spark voltage is induced by the flywheel magnets into each of the Ignition modules (2).

Asking what generator a person has should always be the first question to ask. Saves a lot of confusion and misinformation.

Dave

Dunner's got it hold the start rocker switch down on the stop side, but first I think you might need to add more gas, after holding switch on stop, then you need to hold it on start sometimes for up to 2 minutes before starter will engage then it should start. If you have owners manuel read the section on codes. That blinking light on the start button is blinking a code. Owners manual is very well written and easy to understand a good thing to read from cover to cover.

I don't know about the two minutes; I never hold it in the start position for more than about 5 seconds. If that doesn't start it, I hit the stop position for another 10 seconds.

Two minutes is a long time. Try nuking your coffee for two minutes and tell me how long before you put you lips to that cup.

Had a gen on the houseboat did same thing, start, and run as long as you held switch. After hours, of chasing wires, discovered one of the remote start switches had stuck in the kill position, even tho it indicated it was in the run position. It failed internally, no way to see it. Took so long to find it because i assumed it was working properly since it indicated it was. My fault for assuming, check all switches for internal faults, use a good meter.....

Thanks for the manuals and the 12V correction.

Yah, that's my pessimistic self -- expecting the problem to be hiding in a normal appearing module (fuel pump, volt reg, switch). Will systematically run through the troubleshooting guide for this Gen model. Thanks.

Check and make sure Critters didn't build a nest in your rotor.
Check slip rings brushes.
