RRC Problems

My 93 range rover 3.9 drove fine yesterday went out in it today it started fine and at 1st drove fine then suddenly started holding back,misfiring,backfiring a little,at 1st i thought either the coil,distributer or ht leads would be at fault so nursed it home but when i got back turned it off and the battery light stays on anybody any ideas what could be up

oh and when it was playing up it still ticks over fine

sure its the battery light?

sounds like youve run out of fuel to me

its definatly the battery light and it hasn't run out of fuel it still has quarter of a tank in it and even if it had run out why is the battery light on when i have switched it off and locked the doors?

Thats the beauty of a Rover V8i, works fine one day and not the next ! Becomes a process of elimination. Vacuum hose pulling air in, Fuel pump packing up, OK on tick over but not under load, the temp sensor telling ECU to send wrong fuel mix, gummed up breather on top of LH rocket cover, or throttle body butterfly covered in carbon - I've had all these at different times on different EFI's.

Sounds like your alternator is dead. Take it off and get it refurbed, brushes, slip rings, regulator and diode pack/regulator.

Give classic kev a prize goldfish

it was the alternater the diode was fubared which reversed the function of the alternater thus draining the battery leaving not enough power to run the efi hence the coughing,spluttering and general rough running

pick the refurbed alternater up tommorrow

many thanks for all the help guys
