As above, I have just bought a new to me isuzu and its a great truck to drive, except at night or when backing up
I have assumed that the park/tail/dash lights are the same problem. I have no power at the bulbs for park or tail and I have tested the plug on the side of the transmission tunnel under the passenger seat and no power there either. I have replaced all the internal fuses and the fuses in the engine compartment look sweet.
Could this be a relay issue, there seems to be 2 relays missing from the engine box eb21 and eb27 no idea if they are not there because the options are not on this truck or if they have been removed. There may have been spots on before and someone has borrowed the realy when they sold them.
I can not find any fuse box diagrams in english or any wiring charts for this part of the truck.
The reverse lights I assume is the sensor but I have no idea where this is.
Any help would be appreciated
Colin
