030470 B&S 7000 watt electric starter help...

i need help with this machine.

https://www.briggsandstratton.com/na...generator.html

Purchased new in 2013.
10 hours on the meter.
Been waiting for a power outage so i can use it with my 10 circuit transfer panel.

This thing has a battery for electric start. tried to start the other day and all i got was some buzzing. I was thinking it's the starter solenoid (not sure though).
found a solenoid on amazon. wasn't smart enough to take a picture of the connections before i took the old one off. https://www.powerequipmentforum.com/...face_plain.png Now i can't remember how to hook the new one back up. Blade terminal is obvious. if the terminals are facing you with the blade on top, where does the red from the battery go? where does the black wire that goes to the starter go? i've also got a white wire (with a fuse) that i think goes to the starter switch on the control panel. this one must share a wiring lug with the red or black. which one? Any help would be appreciated.

A relay is just a switch fired by a solenoid. Put the + from the battery on one terminal and the feed to the starter on the other; it doesn't usually matter which is which, but it should be clear when the unit is mounted (based on the position of the wires) as to where they were before. The blade terminal is the hot feed from the starter switch. Any remaining wire would probably be a ground that would go on a mounting bolt. <--Wrong - White is the +12V feeder to the key switch & float jack - see post 4.

P.S. Actually, the picture of the generator at the link you included clearly shows where the red lead is connected when you zoom in...

The wire in question is the white wire.
Turns out, this wire goes to the charging port for the battery.
Having said that, the white wire must share a terminal with the red lead from the battery.
How else would the battery get charged?

Found the wiring diagram (page 22 of your manual) and I can see that the white wire indeed does go to the float jack and has a diode in line to prevent self-discharge, and also goes back to the key switch. I see an 8A fuse in line there, as well.

Looks like the white wire carries the +12V to the key switch, which then sends it back out the B/W wire to the solenoid to fire the starter motor, which gets its +12V via the red cable.
