Dizzy Type

[Stratton Jimmer]

I can't find any identifier on my dizzy to tell me what type it is. Here are a few photos if anyone can help me to identify its brand and model. The last photo with ruler in place, indicates it to be approximately 3" in diameter. Thanks in advance.

It's not a Delco so probably a Lucas variation. Is there a plate on the side (which may be facing the block)? Others have the type printed on the vacuum advance. If you can find the serial number / type number I can reference it.

It could be a Lucas 45D base unit, although the vacuum advance pipe fitting is odd, with some sort of EI fitted. Or it may be something that Triumph never fitted but some PO figured would work.

Looks rather like a 45D6, and the id will be facing the block, so you will need to pop it out to confirm. The numbers will confirm where it originates. (used on later Triumph big saloons?)

Thanks, I will pop it out and see what lies there.

There is an uncanny resemblance thanks Clive.

the revised vac take off i reckon was used when the normal length would cause interference or the vac unit has a damped spring on the outer side 

used in the 80s    unusual for the ad to say bedford as they would generally be ac delco being a GM partner 

certainly has all the looks of 45D6

Well, a google of the part number from that ad shows other people saying it was used on Bedford trucks

I removed the dizzy and found that it is completely anonymous. There are no numbers or letters to be found anywhere on it. The engine (as I think I mentioned once before) was supplied by Yorkshire Triumphs and is of unknown origin as its serial number had been ground off and the characters PBD001 stamped there in place of the original numbers. Guessing that that might be the initials of either a company or a person, does anyone know of anyone having such initials - PBD?

Got in touch with Richard Symonds and he has sent me a link Book2 (mgaguru.com) which shows that 45D6 were fitted to 2000 MkII 72-75, 2500TC 75-77 and GT6 1976.

judging by the ignition leads I am going to guess that it is a powerspark Lucas d6 clone, even shows the same vacuum take off

That looks like it with the high energy electronic ignition. Says should be used with a corresponding coil of resistance less than 1.4ohms...

[Stratton Jimmer]

I think you are spot on in that it is a 45D6 clone exactly like that Powerspark unit. Anyway, I have had the Sixfire running this afternoon and it is sounding pretty good. The Powespark units seem remarkably cheap - less than £70 for their electronic unit complete apparently including VAT and delivery! For now I am sticking with the Pertronix Ignitor 1, Viper 0.7 ohm coil and a red rotor arm. Thanks everyone for your words of wisdom.

Interesting that the site also says dont use copper leads with either their high power or normal electronic units. Might explain some of the failures that have been reported on here...

I bought one for the Herald 1200  a few years back, and it has that off-set vacuum take-off too. I had read other posts on different forums claiming that the advance curves and weights were not correct for the Herald but were simply Landrover base units being sold as Herald items, however I contacted the company and they told me that they're properly set-up units calibrated for each application. I think mine was £45 with the red electronic ignition and rotor fitted.

I have posted before about the ew distributers. It was a club supplied item, and so terrible the car was undrivable. And yes, it ws timed up correctly at idle. Not sure what eventually happened, it did get sent back (and the original worn unit refitted) but the owner has disappeared into the ether. 

So my advice is to check any new distributer. Set the timing, check it gives the full advance at 3000rpm (vac disconnected) and that the vacuum advance works. That would make it about right at least, and takes 5 minutes.

GT6 1976

Nobody spotted that GT6 were no longer made by 1976. I didn't even though I typed it. I have informed Richard of the erroneous "mgaguru" paperwork.
