Auxiliary Start Switch

[sgtlm17]

Does anyone with a 2016 Ford chassis Forester have an auxiliary start switch. This is the switch usually by the drivers side that lets you use the house batteries to start the vehicle in the event your chassis battery is dead. If so where is it?

I have a Chevy chassis but mine is on the outboard (left) side of the driver's seat.

Likewise on my Ford chassis. On the side of the drivers seat base.

Same here. Ford E450 with aux start (uses house batteries) visible when the drivers door is open.

Good to know. Just picked our Forester up a couple of weeks ago.
Thanks!

Maybe a pic? I feel blind lol.

On our 2011 Sunseeker, the booster switch is on the left side plastic trim piece of the driver's seat, near the power seat switches. If I'm standing on the ground and open the door, it's visible. Sitting in the seat with the door closed, I can't see it. The switch has a car battery symbol on it. You press and hold it in to activate it. If you do it with the engine not running and the coach shore line not plugged in, you should hear a click when the battery control center relay is energized. If the engine is running or the shore line is plugged in, it may already be energized and nothing will happen when you press the button.

For your information, if you happen to run the house batteries down, you can use the same booster switch to use the chassis battery to supply 12 volts to the coach system so you can start the generator to recharge the house batteries. (The generator normally uses the house batteries to start.)

Or, you can just start the chassis engine, and in a short time, the battery control center will automatically connect the two systems, so the chassis alternator will supply the coach's 12 volt system. This is what happens when you are driving down the road, and the chassis alternator is supplying power to the coach system. This prevents the refrigerator and other 12 volt users from running the house batteries down while you are driving.

This what it looks like on my 2016 3011.

Ok had to get out there in the daylight. I did find it. It's up underneath the seat. First pic is side of power seat. Second pic is up underneath seat which you can see switch. Thanks for the help.

Wow, that switch is hard to find. Glad you found it and posted pictures, so others who have that setup can easily find there's now.

Yes dealer couldn't find it either during PDI. It is underneath and set back.

I have a 2019 Forester LE on the E-450 chassis. I couldn't find the boost switch because the GD coach manual said it was on the dash somewhere. Had to get online to find out where the switch actually is located. Sure enough, there the sucker is on the driver's seat pedestal.

Thanks for the info folks!
