Distributor low tension lead

[toneil461]

Hi,



Need a liitle help please! Can anyone tell me where the low tension (LT)lead from the distributor plugs into. From memory I think there is a fly lead some where around the rear of the engine near the distributor. TheLT lead is black in colour has an insulated male connector. I know that ultimately it attaches to the negative side of the coil but from memory does not attach directly to it.

Stag has original V8 with twin points.

Regards

You must have a MK2 stag have you? I think from memory that the black wire that you are referring too is connected from the distributor, to a connector that has 2 white wires with slate tracers in them. These white/slate wiresare afeed to the tachometer and from the neg side of the coil.

Hi Les,

Many thanks for your reply. Yes I have a 1975 Mk 2 Stag. I had a high resistant connection in the distributor which caused the Stag to breakdown. I located the fault and bye passed the LT wire (connect a wire from the distributor to the coil).

Unfortunately, as it was gatting dark and on a very busy road,Idisconeected the original LT wire,one end of the wire from the CB's and the other end from a fly-lead at the rear of the engine harness which containedan insulated female lucar terminal. The problem I have now is I have lost this fly-lead!!

If anyone could take a picture showing me where the lead is I would be very greatfull.

Thanks in anticipation of your help!!

I'm not sure I recognise your 'fly lead', but this is the LT wiring on my 1977 Mk2. Ignore the red lead to the +ve terminal as I've got electronic ignition, but otherwise it's standard. The black lead from the distributor goes directly to the -ve coil terminal which also includes a white/grey wire from the ignition loom - maybe your black & white/grey wires were joined together at some point else other than the coil terminal?

Hi Seaside Bill

Many thanks for taking the time to add pic's. I have just taken some from my Stag and the layoutlooks different.

In my hand is the Fly-lead from the distributor, where does it go?. I know it should be attached to the neg side of the coil but from memory it never did. I think there is another lead somewhere between the engine and bulkhead (which I can't find)that attaches to the distributor fly-lead and coil.

I have had a good look around this area, even jacking up the vehicle and placing my hand on top of the belhousing thinking this lead may have slide down to this point, but no joy. Am I totaly bonkers?? My misses thinks I am!!

Again thanks for all your help!

Terry,

I'd just connect it directly to the -ve coil terminal and see what happens - it's where it ultimately needs to go so won't do any harm. Have you got any sort of immobiliser fitted?

Just a thought... is one of your coil -ve termals a female connector? If so, there may have been a bridging wire that's fallen off?

Took some pics of mine hopefully they may be of help, agian ignore additonal wires for electronic ignition!

From your picture a couple of questions, can I assume that the NEG side of the coil is on the right. Why are their so many connections on the coil ?and were do they all go to or come from?Does your tachometer still work if you connect the black wire onto the coil as per Seaside Bills note. If it does then one of the many wires connected to the coil must be the tacho signal feed, and if this is so are you sure that the black lead was not connected directly too the coil.

HiStustag,thank you for taking the time to take pictures,which gave thought do I change to electronic Ign in the future. Your system wiringis different as you probably have 3 wires from the optical unit in the dissy. Mine has just 1.

Les, The negative is on the left, positive on the right (looking at pic). The wiring is standard to the best of my belief and I am reasonably sure (not a 100%) the wire did not connect directly to the coil.IfI cannot find the link lead then I'll put it onto the negative side and that'll be the end, but would like to return it as it was.

The vehicle, over the last 20+ years has run in top condition never failed once!!. Prior to the defective LT wire, rev counter etc was OK. Never really checked to see if it worked after my bye-pass but have no doubts it will.

Again a big thanks everonefor your help!

There are too may wires connected to the coil, normal connections are, on the+pos 1 power (mk2 resisted wire) supply, 2cold start 12volt from starter motor(only live whilst starter is engaged).- neg 1 power supply to distributor, 2 impulse wire to rev counter.

If the coil neg is on the left then were do all these wires go to that are connected. This may seem silly but are you sure that the BLACK distributor was not connected to the end of one of the wires coming from the - neg side of the coil.

If the rev counter still works when you connect the black wire to the -neg side of the coil thenone of the wires must be suppling the rev counter.
