I rewired my truck last year. I went by the book for the indicator,
hazard switch and flasher relay wiring (Except it now goes via a fuse!).
The flasher unit is the big original one with about 6 pins

All was good for a while, but the bulb went in the hazard switch after a
few months and i had to replace it. Around this time i noticed that the
indicator warning light was always dimly lit (it is not obvious unless it
is dark out). This causes my battery to go flat over a couple of weeks if
i dont use the truck.

If you unplug the flasher unit it goes out.

Has anybody got any suggestions? It still flashes properly when it should
and all the indicators work along with the hazard switch.

Am i likely to have a duff flasher unit? or have i missed an earth off
somewhere or something?

Now that it is dark all the time i can see it glowing when i walk past
the truck and don't think it is doing my battery any good.
