Hymer camp 46 talento, fiat based left hand drive

[redrooster]

Hi everyone I've just purchased the motorhome, Had it delivered everything was working fine, Then all of a sudden the indicators and hazard warning lights have gone, The van has been sat for a while I guess because of covid, The fuse box is in the right hand compartment with 4 relay switches but I don't know what relay switch is which because obviously there's no sound I can trace it to, Any ideas anyone one, I'm gonna check bulbs and wiring but need to know which relay is correct one no Manuel etc cheers

I think it should be a 5 prong one. Pull them all out one at a time and look for corrosion or tracking. Just pulling out and replacing could solve your problem.
