Glow plug coil light came up after failed start

[Kharl]

Several months ago, almost a year ago i got that light on, but i just re tighten the wires in the fuse box and it was gone.

Two months ago I was about to start the car and it did not work.
i had to use a jump starter, after it, it came alive,all good, but then there was that glow plug coil light flashing.
The light went of 3 days ago, ad i was happy...
Three days without that light on, cool!
But today the car didn´t wanted to start and i had to jump start it again and did not work , i notice that when trying to crank there was no drop in the voltage, so i knew the electricity was not even reaching the starter, then i give a look to it and i found one of the wires of the starter loose, i cleaned it and put it back and it started like a charm, but the glow plug light came back
