Points to Pertronix

[2manykids4a7]

Hey everybody,

I'm thinking of making the switch. The main shaft on my distributor has some wobble to it, making it hard to maintain a steady gap on the points. So since I'm having to change it out, I'm thinking of going with a Pertronix distributor and ignitor. Has anyone else done the full switch? If so, did you replace the coil as well? Any advice?

I have a 1975 109 FFR that has had the voltage dropped from 24 to 12. The part I'm looking at is a Pertronix D176600. Best deal I have found so far is here

Any thoughts, advice, general know how.

Thanks, Steve..

I think you'd still have some problems with the looseness of the dist shaft, the air gap would be changing constantly, and they(pertronix) don't like that.

It is my intention to replace the whole distributor with a flamethrower unit from Pertronix.

Never mind. Didn't get that out of your original post. I haven't put one in my Rover yet, but I've put them in a bunch of other projects and haven't had any problems. (except if I leave the ignition "on" without running it, fries the module pretty quick) The main reason I went with Pertronix is that it's getting harder and harder to find quality condensers anymore, can't count the condenser failures I've had in the past 10 years. (as opposed to 40 years ago when that was a very rare failure) Oh, and I haven't used one of their coils and haven't had any problems with stock coils.

What is a BMC A or B series engine, which is what that distributor is supposed to fit? I thought that the 2.25 distributor had a unique advance curve, and that not all 45D distributors were the same.

I bought a new old stock Lucas 45D from RDS and installed a Pertronix unit along with their epoxy coil. So far so good, but I've only driven it 100 miles.

before you spring for it

I have a new distributor I accidentally bought from TNTLR. I never used it. I'd let it go cheap. It's a genuine LR one. 712-299-2279

Bkreutz. Thanks for the info.

Jac04. Apparently the part works as a replacement for the Lucas distributor. Check out page 10 (actual page 41) of the flamethrower distributors section of the Pertronix catalog.

Bpj911. PM'd you.

Thank you everybody. Still open to more thoughts on the matter, and input from anyone who has this set up in their rover, or who has chosen to go other routes. Steve..

I have the Pertronix distributor from Summit in my 109 and it has been trouble free for over one year. I still run a stock type coil. I didn't pre lube the shaft prior to installation, and it chirped a bit when first fired up....

I had to install a new distributor because I had the crappy Douche-ele french thingie. One drop of water within 3 feet of it and it would give up the ghost.

Bought a brand new 45D4, installed petronix, never had to fool with it again. Its pretty much awesome and I recommend that course of action.

Thanks guys. From all that I have read the pertronix ignitor seems to get the nod over keeping the original points (with a caveat of keeping a set of points handy just in case). So I think I am going to make that switch for sure. I guess my question has morphed a little bit and has now become the following. Since I have to replace the distributor and I am choosing to go with a pertronix ignitor does it make more sense to switch to a pertronix distributor as well as the ignitor, or do I replace the distributor like for like and only change the points? Does it make any difference? What does everyone think?

P.S. Thanks for all the help, being able to bounce questions off those with more knowledge and experience is really helpful.

Its really up to you. Both work fine. If you go with a 45d, and install the pertonix under the cap, you can carry points and condensor to cover a failure (as you said). If you go with the complete pertronix distributor, you could still just carry your old distributor around to get you home if need be. Either option yields the same results, so which one will cost less?

As far as the coil goes, I know people who run both stock coils for their cars, and the pertronix coils with pertronix units. I hav'nt heard much from anyone either way. If it were me, I'd read through the pertronix warranty to make sure there wasn't some goofy caveat that voided your distributor warranty if its used with anything other than a pertronix coil. I'm sure someone on this board can help with that.

I plan on going with the pertronix dist. you're looking at, so I'm wondering how this will work out for you. Keep us posted.

I went to Pertronix a few years ago - coil, wires, the whole bit. Runs flawlessly. It is my understanding that if they are to fail it will be right after installation. Otherwise it's smooth sailing.

[jac04]

I had heard that some of the knock-off 45D distributors were not of the best quality, that's why I went with a brand new Lucas 45D and installed the Pertronix Ignitor. Does Pertronix make their own distributor, or do they just buy an aftermarket, install their electronic ignition, and brand it with their name? Knowing that may help with your decision.

Just to throw in another data point I have run a Ducellier on my 88. The points are a really bad design. I replaced them with a Newtronics (I think they were bought out by Lumenition a while ago) optical pickup electronic ignition with Lucas sport coil. Its very simple and has done >100K miles with nothing more than the odd cap and rotor thrown at it. Oh, I also put a set of Magnecor leads on which was well worth the money as the stock Rover ones don't like the heat here and wouldn't last more than a year.

[2manykids4a7]

Thanks again to everyone for the advice. It seems like I have a variety of good options, so I thought I'd let the cheque book decide.

After a brief search it seems that the most cost effective way is to go with a new Pertronix distributor, and keep the old distributor with points as a spare if needed. And for now to stick with the existing coil, leads etc.

Before pulling the trigger I will check on the warranty. Not sure how to find out where Pertronix get their distributors from but it seems like people have had some good luck with them, so I will just have to chance that one.

Please don't hesitate to chime in if anyone has any more thoughts. I will post updates as and when they occur.
