SCM fuse to clean chassis batteries

Can someone help me identify the SCM fuse to pull in disconnecting the batteries for terminal cleaning?

Which batteries are you trying to clean, the house batteries or the chassis batteries? If you're cleaning the chassis batteries, just turn off the battery switch.

If you're cleaning the house batteries, disconnect from shore power, turn off the inverter and then disconnect the positive cable to the inverter first. Then disconnect the negative cables and start cleaning your terminals.

Just shut off the 2 circuit breakers below the chassis batteries.

Pull shore power if removing chassis battery cables. Run some stuff to knock off the surface charge so that the big boy opens.

The positive cable could be powered up thru the BIRD.

Turn off the disconnects to the left of the fuses and then pull fuse F10. Spartan doesn't warn or notify owners that you can damage the SCM if you don't pull F10 before disconnecting the batteries. I think it's the inrush current when you connect them that damages the SCM. I learned the hard way.
Spartan Chassis only

Directly from Spartan, on a 2020 Dutch Star Spartan Chassis, anyway:

Chassis Batteries (2) disconnect or replacement procedure: Turn off both chassis battery disconnects in the rear bay. In the fuse box in the rear bay, pull the F10 and F11 fuses. Take pictures of the chassis battery cables for reference because Spartan does not have the battery cable wiring diagram available.

Forgot to mention, after turning of the battery disconnects in the chassis battery bay and pulling the F10 and F11 fuses, when you remove and clean the chassis batteries, make sure you check the water level!

Have fun cleaning!

Two years ago it was F10 only. They must be learning the hard way and making changes. I disconnected my batteries 3 times with no problem (not pulling F10). The next time I connected them the horn started honking and would not stop. They tried to make me pay for a new SCM saying I didn't follow procedures. I said show me where it is documented. I called big Mike from the Spartan class and he never heard of it. They agreed to send me a new one.
Thanks for the update on F11.
