Hi All,
Can anyone help me, I've had a problem with my 2.25 petrol for a while now and have replaced coils, Ht leads, plugs condensers changed ducellior for Lucas 45D4, rotors dizzy caps the lot really.
My problem is I'm melting the heel of the points in both dizzy's.
With new points and every thing set as it should be except timing a little out, she run for about 5 mins then complain and shortly later die. The end result being the points are closed because the plastic heel has melted.
I've been talking to a very nice man, Dom @ LR Series who has been supplying me with genuine and Britpart etc parts. He in turn has been relaying my questions to Land Rover technical support and coming back with replies.
Basically LR say its either coil (2 tried), dizzy (2 tried), earthing or coil wired arse about face. Wiring has been checked and all appears okay I've tested for continuity between engine and battery, had continuity but not sure how good the earth really is.
Have more points arriving tomorrow and intend to use jump lead between battery -ve and engine as another earth.
Have checked bowl of fuel filter bit not gauze and only very, very fine rust found in bowl as would be expected I suppose.
Have checked fuel pump is pumping fuel, zenith was refurbished about six months ago.
All my problems started on the 100 or so mile return journey from Buxton after a gentle weekend off-roading with OLLR.
Anyone have any ideas suggestions etc?
Any comments greatly appreciated as I'm supposed to be on a driver training day next weekend :'(
HHH

If I'm understanding this right, you are talking about the plastic that is moved with the rotation of the distributor cam, to close andopen the points, try a smear of grease round the cam
This where the older points which had a bakelite type fitment rather than plastic faired better with the wear
-
Cheers hobit, I'll put a little more on anything worth a try :)
(its melting where plastic heel joins the body of the points - not a friction problem on shaft)
-
Dont know if it will resolve the problem or show up another fault but have you tried one of those dizzys that have been converted to electronic ignition you can buy them off that auction site or i'm sure that i've seen them advertised in some of the Land Rover mags
-
the only other thing I can think of, off hand does your ignition coil need a ballast resister type, or normal one
also run an extra earth cable to the engine from the battery
-
A bad earth/short?
Are you sure you have then fitted right?
-
Kinda guess on this one as I haven't messed with points for years
It sounds like you have some kind of wiring fault as your points when closed are passing current causing the spring to heat up instead of just dumping the charge from the coil
Do you have the coil wired correctly are there any wet shorts in the ignition wiring?

hi, you need balast resistor i had the same problem years ago took me ages to work it out fitted a balast and no more problem. ;)
