This answer was rated:

i have a battery warnning light problem When I switch on my ignition and start my van
up all ignition warnning lights go out ( battery/oil light ) but after a few seconds the
battery light come back on and stays on while driving What is the fault and what do I need to do My VAN IS A 2005 1800 LWB FORD TRANSIT CONNECT
there good evening to you
Ok this indicates a fault with the smart charging system
The first thing to rule out is the alternator which I susoect will be ok as you have not lost electrical power
The alternator should be charging the battery around 14.3 volts (across the battery terminals )
I strongly suspect your cause will be corroded wiring in the smart charge loom
This is a 3 wire loom that connects to the alternator and then clips to the cooling fan housing upward to a triangle 3 pin plug
This loom is very prone causing this exact concern
This smart charge loom is avaiable seperatly snd is around £15 + vat from memory and takes a few minutes to replace
If you need anymore help or advice on this issue please let me know

Brian just to let you know I had a quick look at my van and

did check wiring from the alternator I did manage find the plug / socket

behind the rad the pins in the plug looked fine but I hav,t had time too remove the plug on the alternator. On Friday mornning I started the

van as normal drove 22 miles to work and back and the battery light

did come on at all parked the van up started the van saturday mornning and

the battery warnning light came on and stayed on

Best Regards ***** ***** PS I looked at the wiring on sunday

Alan good evening to you
Ok to inspect the wiring unplug it from the alternator and the radiator fan joining olug and PPP the securing blood off the remove the isolation and tug the wires you'll find they will come away in your hand due to corrosion
I always advise replacing the loom as it isn't expensive and saves you trying to Repair the old loom
