what to test next gu 2000

[dads tractor]

alt.good, battery under load good, new startermotor, and still has the symtoms of a flat battery.

history this td 4.2 t has always been a lazy starter ,so have run extra earth wire to the block and cleaned the contacts and the glow plug bar as well as replacing the glow plugs. the starter motor was on its last legs the stator was only just hanging in there so new as well.

where to look next; to me being old and gray the next place has to be relays fuses etc so tell me if you have any ideas which panel your in and a good description of how to test.

arnie we need the power NOW

but do you have power to the glo plugs and is the glo plug timer staying on for the correct time / i think its 15 seconde but the braineyaks will be able to tell you

good point there seems like an earth problem guessing you have earthed back to the body as well
anyway stick a bigger charge through her and see if that makes a difference

glo working and can hear timer although need to read what the glo.s are getting

What about testing current draw at starter while turning engine over. Could it be not enough CCA at the starter. Maybe heavy leads to carry more current. Does sound like a lot of if's or maybe's but might be worth a test. Have you tried to bypass ignition and hit the starter straight off the battery?

There are several flat battery sounds a car can make - click click click; or slow rotation of engine to name two.
How does yours go?
There are running tests you can do but I will keep it as simple as I can.
Test battery condition and health.
I wrote about how to do this easily in a thread earlier this evening.
Use a multimeter to check resistance from battery neg terminal post to the body of the startermotor. Should be less than an ohm or two.
Test resistance from battery pos post to starter main supply. Should be much the same as for negative side.
OR
Voltage check between starter motor body and main supply wire (the big one). This should be the same as your battery voltage (or very close).
If there is great resistance, or a difference in voltage anywhere of say 0.3 volts, check and clean every connection.
Ensure the surface between the starter motor and engine is clean as this is where the starter earths itself. If you have replaced this, is the contact surface clean?
I was caught out by this a long time ago, with the same vehicle and starter. I kicked myself hard when I found the mounting surface was painted silver and yet I thought it was good to go.
Paint is an insulator. Bench testing starter worked, in car did not.
As stock patrol eluded to, check the battery is in good health and the CCAs are good.
Then check wiring to and from starter.
You could also measure the resistance of each lead (when disconnected) to and from the starter.
There are runnig tests you can do that are more accurate, but its hard to explain in text

As the post is old, give some feedback on the repairs please?

Thanks lieney for your insite and help the young fella has left that niss in the back yard [thanks dad kiss my ???? ] but bro' and i are heading to Alice Springs to help a mate in the Finke desert race we w i ll get onto it when we get back.

did a load test on the battery and was ok then had my doubts and did a second test and fail two days later .this is the fourth battery in a year and second alternator plus a new starter motor . The young bloke is only an apprentice diesel fitter . his brother just out of his time same trade and dads a firie i'm trying to get them to think it through so if something goes pear shaped in the middle of the Simpson or madigan track they will have a logical thought process. So thats why I canvas people's opion on the net and thank you for your input we will follow the checks and get back to you .

Is always good to get feedback on fault finding things as unexpected things come up from time to time.
Good luck in the Finke desert.
If the starter, alternator etc are new, then I'd be looking at connections everywhere
