hello,

Guardian 004988-4 No s/n rusted off

I just received this unit and have connected the propane and initiated manual start up

In the manual position unit cranks over then fires for 1 second and shuts down immediately and the over-speed shutdown LED begins to flash.

In the auto position unit follows the 10 sec start up cranks over then fires for 1 second and shuts down immediately and the over-speed shutdown LED begins to flash.

I followed another post on here and the advice was to clean the slip rings and brushes. Both of the brushes were clean and the slip rings took very little cleaning to polish up to a bright finish.

New battery, new fuel bottle, new regulator on the alternator (front of motor)

any help would be appreciated
