2006 E450 Sunseeker 3100 battery switch

[Jeeper]

Hi all,

my 2006 Sunseeker 3100 is equiped with the battery bridge switch to power starr the motor battery with the help of the house battery.....

My issue is: when we left the headlight on, we had to bridge the batteries to start but nothing...

There is 2 wire at the switch but where is the battery isolator BIM and what need to be connected. If anyone could share the picture of the connections of their 3100 model...

Thanks

Did you hold down the switch when you tried to start the engine with the house battery? Some switches require that you hold it in position while you try to start the engine battery.
Are your house batteries fully charged? Sorry, I don't know who has a diagram.

Yes, the batteries were fill and the wife pressed the switch full when turning ignition...

Here’s my battery control center panel and connections for my 2018 Sunseeker.

Sorry for picture orientations.

Silly question but I have done it before…was the battery disconnect set to connect the house batteries?

I believe if that is still off then the tie in for extra power when starting would not work.

I’ve forgot to turn that on before when leaving storage.
