You say it blows a 30 amp fuse. Is there a 2nd 30 amp fuse (Check it) if yoru converter is bigger than 30 amps it may have two or 3 fuses in parallel ALL of them need to be repalced at the same time..
Also a shorted cell in one of those batteries can pop-a-fuse rather fast.
The PowerMax 55 amper has two 40 amp reverse polarity fuses. I missed that in the OP where he said a 30 amp fuse was blowing. I can't figure out how he got 26v measured at the converter output terminals with the 30 amp fuse somewhere downstream blown. All very confusing.
Needs to separate the converter from the battery wires and then check the voltage at the empty converter terminals and then on the bare wire ends so we know where the 26v is coming from.
I wonder if that white wire to the bracket shown lower left is the battery frame ground. It has two other ring terminals to it as a sort of neg buss maybe? But that is the old photo when things all worked, so can't be a neg ground on the pos post. Not a clue.
The OP has to come back and explain it all. :)
