Sorry to hear that

I got some good news last week. A friend from this site who wishes to remain Anonymous called me.

So Eileen and myself flew over and collected a Dash and a solenoid block.

Ryanair have no sense of humour when it comes to being overweight.

I mean what's 30 kgs between friends?

 

told her (the checkin Lady) that i had Xmas presents

 

Cut no Ice

 

Guess what I'm on tomorrow?

Hi everyone

 

At approx 1430 today my Mk 11 moved on main gearbox for the first time in 7 years

 

To achieve this I changed

 

The gearbox controller (was OK)

Dashboard (broken gauge)

The main engine switch board (switch gone)

The solenoid block complete (busbar gone, solenoids rusted)

 

I serviced

the Hull main junction box

The hull rear junction box

handbrake micro switch

 

And I had to learn all about the wiring loom

 

I got some great advice from all on this site and assistance, Thank you all.

 

Last thing

the N line in the solenoid block

to get the solenoids to work i had to earth this from the N terminal to the gearbox, so the last problem is tracing back this line all the way

From N terminal to ??????

Anyone know where it terminates and how it gets there

 

And could i just earth it to the box permanently

No speciic knowlege of these beasts, but isn't this an example of the army method of wiring each neutral back to the battery negative to give a fully insulated sytem, as even on trucks etc etc? (i.e. double pole bulbs etc) I thnk it was to do with radio sets or something? :dunno:

 

In which case you should be able to run an earth back via the hull so long as the battery pack is connected negative to earth on hull too?

 

Would be interested to learn more from "them what do know"!!!

CVRTs are all earthed to the hull. If there was a live feed to earth, then cicuits should not operate as there would still be no earth for them to operate through, as it would now be live. In any case, fuses or MCBs (don't know if Chieftains have them) would trip/blow if the current draw to earth was too great.

Hi

 

I believe not seen with my own eyes only google earth that there 'r' three Chieftains plus another two military vehicles in a yard in Eccles / Manchester. I saw the recovery version in a yard in Urmston a few years back. Still there? I've been meaning to go and have a look haven't got round to it yet.

Ok, here we go again

 

I've decided to get the turrets working now

 

As it stands

 

1st Tank, the new one.

 

Psu starts light gos out ,turn knob to non stab, metadynes start ok.

Commanders or gunners thumb controller doe's not control any turret movement.

Gunners,There is a loud click when you pull the lever but no movement.

Commanders, there is a loud click and as soon as you pull it the gun depresses without command

 

2nd tank, the mk 11,

 

the psu will not start

 

pictures to follow

Hi Sean,

 

Behind the commander is a box, you will need to possibly contact Bovington, but in that box are all the control systems for the metadynes etc. You will need specialist help on that one mate.

The clunk sound is GOOD though!! Shows a good contact, but just out of interest, which sort of duplex hand controls do you have on that one?

The newer tiny thumb joystick, or the older type where you pull the trigger and move the complete handle up n down n side t side?

 

Wish I could come n play ...I really do miss the old girl!!

PS.

 

Further thought...Don't happen too often!! :whistle:

 

The gunners stab control is the best place to start, does anything operate differently when you select Stab or non - stab, reason I ask is that on one of ours, the system would stabilise fine in non stab but not in stab!!

Also, not teachin ya t suck eggs... but you are holding the metadyne start up switch for a good 20 to 30 secs eh? Up and Down? ...And ya little red light has gone off before ya sstart to try eh? :-D

They can be tempramental little darlings!

yes fred, about the start up

i learnt that the hard way

hold until you hear the metadynes start

after waiting for the light to go out on the psu

 

I'm missing two fuse's and caps from the PSU in the mk 11

anyone got any?

 

doe's the turret batteries play a big part in the performance of the gun kit?

As far as I can recall....No! ...But...Might not be a bad idea to fit them if you can?

I was on chieftains in service but they were at that time Mk 3s & 4's!!!

 

They may have changed various parts on the system from those days!

The turret batteries were mainly for running radio's, boiling vessel etc when you could not have any engines running but... If you can get them, I would fit them!

 

Sorry I can't help any more mate...wish I could come n get my hands dirty on her with you!
