electric issues no 220volt

[Dustoff44]

1971 58YF
It's rather odd 220v 50A port shore power plugged in. Both top selectors at 220/110 mid selector on port shore. all normal positions. both sides show 115v ac but nothing on 220v gauge. Checked all 115v items are powered but none of the 220v work. Most critical is 220v battery charger. All ac's are 115v.
Any suggestions on where to start troubleshooting problem ?

check both legs on your 50 amp incoming breaker, i have seen one leg with power and the other did not have power...changed the breaker and all was good. this was on a 72 58yf

Check the big Buss fuses at the shorepower inlet. I think Home Depot carries these if you need one. Also try moving the shorepower cord to the starboard side and see if the same problem is there.

All power is normal on Generator
