brake lights stay on permantly , have disconnected brake light switch and wires by air tanks ,still on , the only thing that turns them off is pulling the fuse ?
Hi, have you disconnected the plug to switch on top of service brake cylinder ? (brake light control switch on top of cylinder,seen under front panel ,.it's just that you removed connectors by air tanks?

im an auto electrician and i had one of these the other week. it turned out to be the relay in the fuse box that had the contacts burnt together due to use. replace the relay and u should be ok
