2018 GD Imagine Electrical issues

[Wendy Mc]

I have a 2018 Grand Design Imagine 2400BH. It spends a lot of time in storage. After sitting for a couple of months, we tried to turn on the lights. We turned the battery switch on and it instantly blew the 2 35 fuses. We replaced the fuses, turned the battery switch off and turned on the generator. Everything was great. When we turned the battery switch on, it blew the same 2 fuses. We have never had any previous issues.

Those sound like the reverse polarity fuses, to prevent the battery being connected incorrectly. Verify the negative battery cable is the one connected to the camper frame.

Some additional questions to help paint the picture.
You
Mentioned sitting for a couple of months. Was it at your home or in storage?
Was it covered?
Did you disconnect the baterry(ies)?

What you are experiencing sounds a lot like short to power or short to ground.

Potential reverse polarity as was mentioned. Potential loose connections causing shorts, or…the dreaded mouse chew. Perform as much visual inspection as possible.

the dreaded mouse chew

That was my first thought.

Sounds like the battery is hooked up backwards...reverse polarity fuses.

Just my thought , if the batteries were hooked up wrong how would the generator start

Easy, it is a portable generator, not onboard.

Imagines do not have onboard generators....
