Hi all,

New to forum. Appreciate your help.

Magnum MMG25FHI with Isuzu 4LE1 engine with 9500 hours.

I understand that Genarac bought Magnum out as I have been sourcing information on this unit.

The engine runs for about 5-10 seconds and shuts down. I have to wait to stop solenoid to count down and then try again. On the fourth time it runs. After failed start the display shows over speed.

When the engine is running it’s running fine. The voltage display shows different bolts at L1,L2,L3.

Any suggestions?

Thank you.

Aussy.

Got any pictures of the control system? Early Magnums were kind of a hodgepodge of parts that looked like it was built by some guy in his garage. I have ideas but I want to see what it is first.

Thank you for your support.
I don’t have any but can get them.
I have noted that the stop solenoid (2 wire) is not holding the plunger in when the engine is running causing the rack to hunt. Am I correct in assuming that the 2-wire is energized to run?

Thank you
