I have a 2019 Zinger Lite 18BH model and have an issue where Fuse #6 seems to blow fairly often with no accessories in the RV on. I notice it after I unplug the camper from 110V household outlet and try to use accessories off battery power. I troubleshoot and always find Fuse #6 to be blown. This has happened 3 times in the last 6 months. Camping World did some troubleshooting on it since it's under warranty and simply replaced the fuse with a 15amp fuse (I'm assuming that's what it was built with?).
I reached out to Keystone RV directly and this was their response - they say it should be a 30amp fuse, but to confirm with the selling dealership (not sure why the selling dealership would need to verify what the design is supposed to be??):
" I believe that circuit 6 is the recharge line and Iím showing itís a 30AMP. Are there spots for 2 fuses at 15amps. If not then Iím not sure why there is a 15 in the 30. Iíd recommend to contact the selling dealership on that. I donít want you to get yourself in to trouble if the information we have on our side is wrong. It may have been changed in production and not updated on our end.
Please do follow up on the inquiry with your selling dealership."
One additional piece of information: I believe the issue I'm having is identical to what's documented in this TSB (not for my model), where Fuse #6 was shipped out from the factory with a 15amp fuse instead of 30amp fuse: https://static.nhtsa.gov/odi/tsbs/20...57855-3763.pdf
Is a 15 amp fuse the correct rating for fuse #6? If others have this model (or similar), could you please confirm?
It seems small to me, but that's what it came with. On the circuit board itself (see picture) it says "F5&F6 Position; Max. Rating: 30 amp; For Battery and Slide Out Used". I suspect simply swapping in a 30amp fuse would fix the problem, but want a concrete answer that the circuit was designed for that since it's really the minimum gauge wire in the circuit that matters, which I don't have visibility of.
Thanks in advance!!
