ECU
2006 T1n 118 Sprinter
I'm still working on my Aux battery install. Two AGMs under the passenger seat of my T1n. I will install a relay where the factory one seemed to go, under the driver seat. I picked up the PDF for factory install (T1N_Retrofit_Aux_Battery.pdf).
Two kind of related questions.
I want to put a fuse at the battery location, but what rating?
I have been stuck a few times from dead batteries, so I want to be able to jump start from the aux batteries. I would think the easiest way is to force the relay closed with power from a switch, only to do the starting then flip switch off. So the fuse at the aux battery would have to be enough to take the starter draw.
Only a guess, but I'd think that 200 to 250 amp fuse would be needed.
I've searched to site but haven't found anyone setting up to do the jump starting. Is it a bad idea?
PS. I'm putting the inverter in the back in a wheel well box I'll build. With a 118, it will be a shorter run.
