12V fuse question

[jjrbus]

I am redoing the electrical in my 93 Toyota RV. I know enough about electrical to know I need to ask questions about all the things I do not know.

I picked up a WFCO NOS power/distribution panel without any paperwork. I am wondering what the 2 30 amp fuses are protecting? Anyone know??

I have never posted picture on this site and not sure it will show? Jim

Thanks for the responses, greatly appreciated. I knew there was some white stuff on the green, but could not read it. Got a magnifying glass and that's what it says.

I will try to give you something more challenging next time. Thanks Jim

Looking forward to the challenge - good luck with your wiring project :0

If you have a smart phone, it makes a great magnifying glass - snap a picture and you can zoom way in 🙂

agreed with above - the circuit board even has them labeled reverse batt(ery) protection fuse

They are reverse polarity fuses. If battery is connected up wrong they will blow to protect the electronics in the converter.
