m reg 106 diesel won,t start

When I turn the key the glow plug relay buzzes and the dash lights go
out. Ive fitted new battery and glow plug relay, any ideas?

Have you checked you have voltage at the glow plugs when the key is turned.
It should remain there for 20 seconds after the key is released.
The glow plugs are operated by current so if voltage is present the next
check is to remove the plugs if easily done and check that they glow red
when 12V is applied. If taking the plugs out is a pig remove the lead to
them from the relay and insert a DC ammeter. Each plug should draw 12 Amps
this will change as they heat due to the resistance changing

Have you or can you check the earth it might be that.on my 405 i had the
same problem, and found out it was the earth at the box, so i had to
rewire earth to diff place, now works fine.good luck.

 

If all the lights go out and the starter will not turn, then you have a bad
connection to the battery. Check the battery terminals, and the other end of
the earth wire to the gearbox, and body.
If you have a voltmeter to hand, check the battery volts when someone tries
to start it. If the battery does not drop at all, then this confirms the
above. I am assuming that there is nothing wrong with the battery of course.
Not impossible for a new one to be faulty.

Thanks for reply,i,ll check

 

I got into car today and it started,when I tried it again,same
problem,cleaned up earth and battery terminals,now no power at all
battery is ok!!!!!!

 

Have you had the starter motor checked? i think you should look at that
end now.

 

Ok thanks,I was wondering if there was a relay problem,there used to be
a click from behind the glove box?

 

Have a look behind the glove box.it could be the one for the glow plugs.

 

Any idea which one?
