So silly me left the ignition on all day

whilst working on my
1988 t25 1900 camper. I could smell something burning but didn't realise it was coming from my van ! durr. Next day battery was flat so recharged it. van started ok but indicators and hazards dont blink, just the little green light in dash stays on. I have checked the wiring the best I can and also checked the fuses and renewed the flasher relay but problem persists. Any Ideas where I can go from here

Thanks
More Info for above, there is no power to indicators but green light in dash stays on
