TB42 sluggish starting

[micks troll]

G'day all Ive got a starting problem on my TB42 thats being hard to track down . When I go to start it it's very sluggish to turn over. I checked the battery with a mechanic and he reckoned it was down in one cell. So i went and bought another N70zz about 600cca (compare to my old being 780cca) and swapped but it still did the same thing. I than went around and cleaned all the earths and it made it slightly better, but not good. I have taken the starter to a sparky to look at in case it was tired but they said it was fine.....

I have now had it serviced and tuned new plugs, points, tappets, replaced some vaccum hoses and it also has a new ignition coil and timing done. Runs great when running but still hard to start Alternator is a 140 amp and is charging fine and with a new battery it shouldn't be the problem either. Please help if you have the answer

Also the motor is only 20,000ks old and the starter is only 5years old and I dont like or play much in mud as thats what killed the old one
I'm fairly anal about cleaning the engine bay more than the rest of the 4wd!

Cheers Mick

i read and thought about this for a while, and the only thing in my mind that may be wrong are the HD leads from the battery to the starter motor. I could only suggest at getting some new ones made up and see if that takes care of the problem. Copper oxidizes like all metals, so maaayyyybbbbeee the leads you have atm are shot?????

Cheers Mate that's an easy fix to try. I still reckon the starter may have a bit to do with it as I took it off to take to the electrician so they didn't test underload. Thanks again.

I had a starter problem with my gq td42, took me a long time to figure out. it was real sluggish like yours to start, but when i tested the starter off the car it worked fine. Then i put a new starter on it and problem was fixed.
So it could be your starter.

have you got any mates with one you could steal and test?

Hi check to see if your patrol has a relay on the syarter circit, if not put one in and see if that helps, I know on a lot of the old fords and holdens once they got a few years on them they had to have a relay fitted into them and that fixed it.

Mine is doing the same!!!

Replaced the battery as it was 4 years old and no help! Mine is the original starter i think.

Check for hot connections on your battery cables or terminals and earth points etc, a hot connection is a bad point, dirty or poor connection you loose current, if battery leads themselves are getting hot your starter may be drawing excessive current...

Try running one side of a set of jumper leads from your neg on your battery direct to the engine block, may be a bad engine earth?

Try running a set of jumper leads or something straight from your battery to your starter on the car and trying it, if it cranks over well you know its the factory cables or something but if it still starts like crap you know its your starter motor...

Testing a starter on the test bench or even pulling it down doesnt always show the fault or put the same load on the starter as it does when the starter is on the car... but usually a faulty starter motor when pulled down the fault is evident...

Cheers guys. All earths are good and have no hot lines as all have been well cleaned and never get hot I've got custom earth leads as the factory ones are S^#t (I worked for an autoelectrician for a while hence the 140amp modified alternator etc also). I'm fairly certain now that it's the starter as have tried most other ideas available. Cheers for your help I'll pull the starter back off and put some new brushes in and give it a good clean up. I'll keep in touch
Cheers Mick

Check the contacts in the solenoid on the starter.I had a similar problem years ago on a pulsar. Had to replace them on a mate's Landcruiser as well.
