Onan diesel generator cold start
To prime my generator (get the air out of fuel line) I hold the bottom of my generator start button down for several seconds then push the top of the button to start. Does this also activate the generator glow plugs or does this require a separate function? If its the same function I know I should hold the prime button down much longer. Couldn't get it to turn over this cold morning and it usually starts right up. Plenty of fuel, recently serviced. I assume the block heater button is only for the coach engine.
