Moomba Kanga 2000

Hi,i had a key break inside the cylinder, I unplugged the cylinder and was able to remove the broken key . once it was back in dash problems started when i turn the key to the first position all the gauges and accessories worked ok , when i turned the key to the next position to run the starter heard a click and everything went Dead . After about a half later i had power again till i tried to start. checked all the dash fuses were fine .
the switch was wired red purple stripe to B Yellow to S and purple red stripe to I

is there something i'm missing the dealer said there was a main fuse to reset the only big breaker i found was on the back of the engine block . reset it and no change. Need Help
