battery disconnect on 90 grandvilla

I know that the handle on the floor right inside the door is the disconnect for the house batteries.

However, is there a disconnect for the engine battery somewhere?

No disconnect for engine start battery bank.  And the door switch does not turn off all house battery drains on our coach, as it leaves the fridge and detectors powered.

Thanks, Barry & Cindy,

I have some tail lights that need replacing, and their sockets cleaned up some. The person helping me said I needed to disconnect from the batteries before. So, would I have to take the wires off the chassis/engine battery to do that? So that I don't shock myself?
Is that accurate?

I don't think 12v is gonna shock you - unless you catch it thru a horn relay or something like that....which steps it up to more than 12v. Doesn't it require around 70v. to overcome skin resistance?

You don't need to disconnect anything to work on taillights just dont turn them on. 12 volt DC will not shock you. No danger other than blowing a fuse if you short a hot to ground.

Absolutely no need to mess with battery connections.  Each tail light assembly has a plug where it connects to wiring harness.  Remove the fiberglass cover from the back side of the lights, then you will see the plug.  Disconnect that - you're good to go.

Link below to my thread about refurbing our tail lights.  Even if yours are slightly different, the principle is the same.
