300tdi

Was a new 1000cca Battery installed last year, i doubt the battery is knackred already (id fooked off if it was)

Earths are a possibility. Can you point me to the main engine to earth terminal ?

stick a jump lead from the bat neg to engine block to test.

300tdi, main earth is on back of the gearbox/transfer box on mine, 2 connected at same point, one to batt, other to chassis, under passenger side, next to battery box.

other earths, one on bulkhead to right of the servo, and 2 on one stud to either g/b or chassis under drivers side

Tried that, made no diffrenece

Plugs or fubar starter motor im guessing


Feels like something is draining that battery tho
Should be fine after a 19 hr charge. Il investigate with the multimeter

i'd forget the plugs. when the battery is charged, does it turn over quickly or slowly struggling?

If quickly for a while, then i'd look at fuel leak back. if slowly, then recheck the connections, try smacking the starter with a hammer.

multi tests, whack volts across the battery and leave there. it should read above 12.4 volts to begin. start it, voltage shouldn't drop below 9.6 volts, then when it's started and alt kicks in it should go up around 14.

voltage at battery fitting : 11.6
when starting voltage drops to 5.7 to 6.9 and is fairly slow and pathetic
(Noticed a buzzing noise when key is half turned, is that normal ?)
Took battery out (never started) voltage = 11.5
charging in shed voltage 11.59 atm

I am charging it with quite a ****y looking charger (looks like an ac adapter with 2 nipple clamps coming off it... could be useful in the bedroom)

Ther is your problem a leisure battery is made for a caravan to take plenty of charges and its lets its power out slowly for long periods for 12 v lights small water pump draw. Not a friggin heavy draw starter motor .
Plus leaving any battery to lose its charge and sit discharged in cold weather is in most cases the death of a battery .

it might have been drained with you dicking on though. give it a good charge until full and try again.

was it a numax cxv-x? lot of people use them and they have a 3 Years Guarantee

do the tests again when it's fully charged.

A deep-cycle battery is a lead-acid battery designed to be regularly deeply discharged using most of its capacity. In contrast, starter batteries are designed to deliver short, high-current bursts for cranking the engine, thus frequently discharging only a small part of their capacity. ...

yup, however the numax cxv-x has been recommended around all the forums for a while now. if they all dies within a year or so, i'm sure we would have heard about it.

also it is marketed as a 1000 mca cranker and 'Deep-cycle & Starting', so it should be fit for purpose.

Or the fact that boats and motor homes and most cars they are fitted to start good down to servicing ect the one that have trouble and require many cycles to start kill leisure battery's .

is it really a leisure battery? seems odd since it's designed to crank 1000 mca. :confused:

have a butchers: Numax CXV-X 1000 Amp - Leisure Batteries - Numax Leisure Batteries

so this one looks like a hybrid. not a true starter or a true leisure but looks more like a starter to me.

'A positive plate of low antimony alloy for better resistance to deep discharge.

A negative plate of calcium alloy to improve shelf life (approx 6 months).'

'Superior ‘Dual Purpose’ Leisure and
Marine battery
Calcium technology
30% more starting power
Exceeds O.E. specification
Sealed maintenance free
Full three years guarantee'
