Thanks Ploggo...thanks AG.
Fitted new batteries....
1.. start motor, no prob`s
2..batteries reading 12 v.
3...running motor 12 to1500 rpm for almost
exactly three mins bat`s still reading 12 v..
then..up she comes... needle flips over to 13 .5 volts
4..switch off run test again...charges straight away....BUT
..wait one hour or so and...same as before...it has to run for
three mins before it starts charging..
(so iv`e told the long haired one to go the long way to the
shops !!!) seriously chaps..it must be some control circuit.
.I`m rooting throu` me bits to see if i`ve got an old shunt
so i can measure the current drawn on starting..and any
further drain on the bat`s when she`s switched off..
But thats going to be mid week before i can get around to it.
will inform if i get to the root of prob`
Regards peter J..
First of all how long since you had the new batts fitted, have they did they
receive a balancing charge ??
I believe that you will have a 2.2 kW starter motor fitted,
When you turn the key you will first of all experience an" Inrush Current"
which will be much greater than the cranking current if you want actual
figures let me know
When you measured B/V which batt did you put the M/M across looking at the
engine bay from the Rad ??
Youre first results appear low, is your MM correctly calibrated. Since
fitment of the new batts how many engine starts against the time the engine
has run & of course what conditions ?
What is the A/HR rating of the batts u had fitted
