New member here. Trying to get info on this geny
« on: June 24, 2024, 03:25:40 PM »
Was given this generator maybe 15 years ago and want to see if I can get it running for an off grid shop I am finishing. Besides being 6HP I am not sure what year and model it actually is. If someone can point me in the right direction I would appreciate finding a service/operating manual for it and the head. If anyone has plans on welding a crank handle that would be great too. These are the plates I could find on it

Model is a SR1 single cylinder air cooled.   Couldn't tell you the year.  Do a search for that model, you'll find a manual somewhere

G`Day Raymason. I have fixed a couple of these Brush SCAF type generator heads. They are unusual in that the rotating armature incorporates the generator windings with slip rings and also a starter motor/dc generator with a commutator ring. Your model appears to have 8 slip ring brushes, so you should be looking at 4 slip rings. My best guess is that you have one neutral, one 240 volt and two 110 volt slip rings.
There are four commutator brushes which feed the built in 12 volt DC starter motor. This also acts as a DC generator which recharges your battery while the generator is running.
The engine RPM determines the AC frequency, yours appears to be set at 1800 RPM to give you 60Hz to match the 110 volt/60 HZ grid in the USA. You may need to reduce the RPM to 1500 if you live in an area with a 240 volt/50Hz supply.
The `A` at the end of the engine serial number normally indicates that this engine is designed to turn anticlockwise.
Could you please post some photos of what you find as you investigate further.
