Help needed ! re battery change on td 5 90

(1/3) > >>

T30CDB:
This morning i changed my main battery for a new one. having completed this i turned the ignition to hear a buzzing sound. THis lead me to the main relay under the passenger seat which was causing the buzzing. I swapped a few relays round and it still did it. I now have only a very faint glow plug light and engine synmbol next to it on the dash. any ideas would be much appreciated

extreme90:
poor earth  :-.
does the temp guage go up ?
or as daft as a flat battery

T30CDB:
seem to have about 1.2 volts when testing from earth to chasis. yes the temp gauge goes straight to the top. do you know the answer  [-o<

Axetamer:
Sounds like a flat battery, the 12v is a nominal figure, I've just tested mine at the anderson connector and am getting 13.8v, I would put it on charge overnight and test it tomorrow

90Mike:
Don't worry about the 1.2v Chris that was my fault  :roll:
The problems only started after the battery was changed for a new one  :-k the temp gauge does go up into the red but only when the main ECU relay ( the one buzzing ) is removed and the ignition is switched on.Is it possible that the ECU could of damage when the battery was changed over  :evil:
