yep
get a multimeter
set it to V (direct current or DC)
put the probes separately on each terminal of the Battery
read off the reading

ideally you want any thing over 13V when the engine is running

thanks t25daisy i will pm u after i have looked a bit closer tomorrow.my battery light came on so i changed the battery and i have a battery gauge to show volts and with engine running it went to over 13 so i left it running awhile and when i went back out the volt was dropping to under 11 but i know the battery is fine is there something im missing. i have a split charger could this be faulty.i can do most things but electricky has me stomped.thanks again for any replys [ ok im thick ]

Your charger relay may be stuck on the leisure battery side or the wire to charge the main battery has come off.

yes..
Your Batt light comes on signify there is NO CHARGE from the alternator..NOT that you need a new battery.

the engine is then using your battery to run the engine... and that won't be for long!

is there something im missing

yes, a working regulator/rectifier.
take off the alternator, remove the regulator.. and replace it with a new one they cost £10

thanks for quick and very good replys,i will now get it sorted

Yep that happened to us in Northern Ireland last summer.
Sorted in 1hr by a helpful auto electrician in Belfast at 3.30pm on a Friday afternoon.....PHEW!!

New regulator fitted and a wire had snapped.

No Em
the brushes are part of the regulator/but they are usually changed as one part.

Regulator looks something like this with carbon brushes

VAG 1009 is an aftermarket part number and the replacement I ordered for my 90amp/hr Bosch alternator....they are NOT all the same so the company will ask for the number off the red label on the body of the alternator so they can cross reference the number to the correct part. Mine has been fitted over a year now and going strong.
Also.....you do not have to remove the alternator...just the two retaining screws in the regulator pack...you may have to undo the adjuster bracket and take off the belt in order to gain enough room to get straight on the screws.
