12volt issues Battery

[JMBO]

Opened camper this year had no problems. Checked the other day no interior lights or 12 volt accessories. Noticed the 2 30 amp fuses in converter marked main had blown. Changed them and power came in for about 3-5 minutes then went out checked the 30 and 15 breaker they had popped. Did not pop the first time. Fuses still good that I replaced. Did some tracing and feel the battery switch is not cutting power maybe defective but not sure. Any ideas?

Pictures would help. Two 30 amp fuses are usually "Reverse Polarity" fuses of by themselves. Don't know what main is. What 30 and 15 amp breakers tripped?

If the 30 is the main breaker than the problem is with the 15 amp circuit but neither would have anything to do with the 30 amp fuses.

SO yes you are correct the 2 30 map fuses are marked reverse polarity, the 30 amp breaker is marked refer, gfci, kitchen, bath and exterior, the 15 amp is marked utility my hunch is the gfci maybe shorting

out?

Attachment 59356 out?

You are not reading correctly. The 30 breaker is the Main Breaker. The first 15 is the GFI circuit. The next 15 should be the remaining 120 volt outlets. The 20 is the A/C. BUT the whole schedule from there on is not correct. You will have to trial and error with a helper to see what each breaker does.
