I will check for the fuse box under the "hood" tomorrow. There are two (or one and a half) fuse boxes under the dash. one is grey and mounted on the firewall, the other is smaller and black. just hanging under the dash, not mounted to anything. I'm in Heber.Emergency Flashers 2003 Workhorse Chassis Allegro 35DAOn my last trip I noticed the emergency flashers did not work. I checked all the fuses under the dash. All were fine. ( I cant find a legend on the fuses so I had to test every one). I swapped the two flashers, signal and emergency, They both worked on the signal circuit but neither worked on the emergency circuit. I noticed that the signal lights will not work if the emergency flasher button is engaged I guess that is normal. Don't know if this is related, normally the backup camera comes on when the MH is in reverse. While driving the last time, the camera would come on when the lights were on and the brake was engaged. I think somehow the power is feeding back through the brake lights. It also happens when the lights are one and i signal but it camera flashes off and on with the flashers. This does not happen if the lights are off. Any help finding the problem or finding a wiring diagram for this MH would be appreciated.
