V8 suddenly died WTH
« on: August 20, 2019, 07:44:21 AM »
Started firing the motor after the rebuild and getting the settings.  Motor

fired on first revolution.  Timing set, got carbs close at idle.  Real smooth.

Shut down to set up vacuum synchronized sticks filled with mercury, took 30

minutes.  No restart, not a pop, puff or fart.   I am suspect of the

Lumenition ignition system.



I found illumination to perform very well 2/6500 RPM on the Dino. Didnbt

miss a beat, I think the light -based unit is the way to go but I understand

these guys are gone. Does anyone make a light / chopper ignition system that

fits the stock TR8 distributor?

The Lumenition is quite easy to fault with a voltmeter , do you have their

instructions?

I have a copy on My Drive if this link works see bottom of page 2 onwards.

Rimmers still carries the Lumenition system and the Fast (Crane) X700 I

believe will work and is also is light based.

I recall hearing that Crane discontinued the shutter wheel kit for the TR8

distributor. I hope I'm wrong because the Crane setup is more reliable and

less expensive than the Lumenition.B

Wonder if I can use the Lumenition shutter wheel?

Just talked to FAST concerning the shutter wheel for the Lucas V8 distributor.

They do not have a kit with that shutter wheel and will not provide a kit for

the Lucas V8 distributor.

No, the Lumenition chopper wheel cannot be used with the Crane ignition.B

They work on opposite principles.B  In the Lumenition, the coil is triggered

when a blade on the chopper wheel interrupts the light beam.B  In the Crane

unit, the coil is triggered when a gap in the shutter wheel allows the light

beam to connect with the receptor.B

If you know what part of the Lumenition is bad, Merlin Motorsport out of

the UK has the individual Lumenition pieces for sale.  Also, they have the

complete system for less than Rimmers.  https://www.merlinmotorsport.co.uk/

Does anyone have a good shutter wheel they can temporarily part with so that a

CAD model can be drawn up?  The file can be sent to anyone and a 3D printed

part can be made easy enough.

I have one that has an injured foot.  It works just fine and the dimensions

of the missing foot could easily be extrapolated from the others.  Let's see

if a more "whole" one shows up, but the offer stands.

Seeing as how I left the ignition on last night, all night, greatly exceeding

the 10 minute limit described by Lumination, if it wasnbt toast I think I

can assume it is now. So I am going to get a pertronix. If you want a

perfectly good Lumination shutter wheel I will send it to you.

It's a shame that Crane stopped making the ignition kit for TR8's. When I

bought my TR8, it already had the XR700 system installed and it's worked

flawlessly for 20 years now.

Crane, the company, shuttered but sold the IP to another company (I forget

who) who is now manufacturing the same system which are available though the

usual outlets (eg: Moss motors).

I agree with your assessment.B  I put one on my TR6 in 1997 or so and it is

still working flawlessly.B  I also had one on my TR8 for the 9 or so years it

was on the road.

While I don't have a TR8 or a V8 TR7 I do have the skills to draw the part up

and would share the file with others if they want it.  Bill if you are willing

to send it to me I will create the CAD file and then I can return the part to

you.
